Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: samsung: Fix refcount leak in aries_audio_probe
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.

Summary
In the Linux kernel, the following vulnerability has been resolved:
icmp: change the order of rate limits
ICMP messages are ratelimited :
After the blamed commits, the two rate limiters are applied in this order:
1) host wide ratelimit (icmp_global_allow())
2) Per destination ratelimit (inetpeer based)
In order to avoid side-channels attacks, we need to apply
the per destination check first.
This patch makes the following change :
1) icmp_global_allow() checks if the host wide limit is reached.
But credits are not yet consumed. This is deferred to 3)
2) The per destination limit is checked/updated.
This might add a new node in inetpeer tree.
3) icmp_global_consume() consumes tokens if prior operations succeeded.
This means that host wide ratelimit is still effective
in keeping inetpeer tree small even under DDOS.
As a bonus, I removed icmp_global.lock as the fast path
can use a lock-free operation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/hfi1: Prevent panic when SDMA is disabled
If the hfi1 module is loaded with HFI1_CAP_SDMA off, a call to
hfi1_write_iter() will dereference a NULL pointer and panic. A typical
stack frame is:
sdma_select_user_engine [hfi1]
hfi1_user_sdma_process_request [hfi1]
hfi1_write_iter [hfi1]
do_iter_readv_writev
do_iter_write
vfs_writev
do_writev
do_syscall_64
The fix is to test for SDMA in hfi1_write_iter() and fail the I/O with
EINVAL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ipv4: fix route with nexthop object delete warning
FRR folks have hit a kernel warning[1] while deleting routes[2] which is
caused by trying to delete a route pointing to a nexthop id without
specifying nhid but matching on an interface. That is, a route is found
but we hit a warning while matching it. The warning is from
fib_info_nh() in include/net/nexthop.h because we run it on a fib_info
with nexthop object. The call chain is:
inet_rtm_delroute -> fib_table_delete -> fib_nh_match (called with a
nexthop fib_info and also with fc_oif set thus calling fib_info_nh on
the fib_info and triggering the warning). The fix is to not do any
matching in that branch if the fi has a nexthop object because those are
managed separately. I.e. we should match when deleting without nh spec and
should fail when deleting a nexthop route with old-style nh spec because
nexthop objects are managed separately, e.g.:
$ ip r show 1.2.3.4/32
1.2.3.4 nhid 12 via 192.168.11.2 dev dummy0
$ ip r del 1.2.3.4/32
$ ip r del 1.2.3.4/32 nhid 12
<both should work>
$ ip r del 1.2.3.4/32 dev dummy0
<should fail with ESRCH>

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ipv4: fix route with nexthop object delete warning\n\nFRR folks have hit a kernel warning[1] while deleting routes[2] which is\ncaused by trying to delete a route pointing to a nexthop id without\nspecifying nhid but matching on an interface. That is, a route is found\nbut we hit a warning while matching it. The warning is from\nfib_info_nh() in include/net/nexthop.h because we run it on a fib_info\nwith nexthop object. The call chain is:\n inet_rtm_delroute -\u003e fib_table_delete -\u003e fib_nh_match (called with a\nnexthop fib_info and also with fc_oif set thus calling fib_info_nh on\nthe fib_info and triggering the warning). The fix is to not do any\nmatching in that branch if the fi has a nexthop object because those are\nmanaged separately. I.e. we should match when deleting without nh spec and\nshould fail when deleting a nexthop route with old-style nh spec because\nnexthop objects are managed separately, e.g.:\n $ ip r show 1.2.3.4/32\n 1.2.3.4 nhid 12 via 192.168.11.2 dev dummy0\n\n $ ip r del 1.2.3.4/32\n $ ip r del 1.2.3.4/32 nhid 12\n \u003cboth should work\u003e\n\n $ ip r del 1.2.3.4/32 dev dummy0\n \u003cshould fail with ESRCH\u003e\n\n[1]\n [ 523.462226] ------------[ cut here ]------------\n [ 523.462230] WARNING: CPU: 14 PID: 22893 at include/net/nexthop.h:468 fib_nh_match+0x210/0x460\n [ 523.462236] Modules linked in: dummy rpcsec_gss_krb5 xt_socket nf_socket_ipv4 nf_socket_ipv6 ip6table_raw iptable_raw bpf_preload xt_statistic ip_set ip_vs_sh ip_vs_wrr ip_vs_rr ip_vs xt_mark nf_tables xt_nat veth nf_conntrack_netlink nfnetlink xt_addrtype br_netfilter overlay dm_crypt nfsv3 nfs fscache netfs vhost_net vhost vhost_iotlb tap tun xt_CHECKSUM xt_MASQUERADE xt_conntrack 8021q garp mrp ipt_REJECT nf_reject_ipv4 ip6table_mangle ip6table_nat iptable_mangle iptable_nat nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 iptable_filter bridge stp llc rfcomm snd_seq_dummy snd_hrtimer rpcrdma rdma_cm iw_cm ib_cm ib_core ip6table_filter xt_comment ip6_tables vboxnetadp(OE) vboxnetflt(OE) vboxdrv(OE) qrtr bnep binfmt_misc xfs vfat fat squashfs loop nvidia_drm(POE) nvidia_modeset(POE) nvidia_uvm(POE) nvidia(POE) intel_rapl_msr intel_rapl_common snd_hda_codec_realtek snd_hda_codec_generic ledtrig_audio snd_hda_codec_hdmi btusb btrtl iwlmvm uvcvideo btbcm snd_hda_intel edac_mce_amd\n [ 523.462274] videobuf2_vmalloc videobuf2_memops btintel snd_intel_dspcfg videobuf2_v4l2 snd_intel_sdw_acpi bluetooth snd_usb_audio snd_hda_codec mac80211 snd_usbmidi_lib joydev snd_hda_core videobuf2_common kvm_amd snd_rawmidi snd_hwdep snd_seq videodev ccp snd_seq_device libarc4 ecdh_generic mc snd_pcm kvm iwlwifi snd_timer drm_kms_helper snd cfg80211 cec soundcore irqbypass rapl wmi_bmof i2c_piix4 rfkill k10temp pcspkr acpi_cpufreq nfsd auth_rpcgss nfs_acl lockd grace sunrpc drm zram ip_tables crct10dif_pclmul crc32_pclmul crc32c_intel ghash_clmulni_intel nvme sp5100_tco r8169 nvme_core wmi ipmi_devintf ipmi_msghandler fuse\n [ 523.462300] CPU: 14 PID: 22893 Comm: ip Tainted: P OE 5.16.18-200.fc35.x86_64 #1\n [ 523.462302] Hardware name: Micro-Star International Co., Ltd.

Summary
In the Linux kernel, the following vulnerability has been resolved:
l2tp: prevent possible tunnel refcount underflow
When a session is created, it sets a backpointer to its tunnel. When
the session refcount drops to 0, l2tp_session_free drops the tunnel
refcount if session->tunnel is non-NULL. However, session->tunnel is
set in l2tp_session_create, before the tunnel refcount is incremented
by l2tp_session_register, which leaves a small window where
session->tunnel is non-NULL when the tunnel refcount hasn't been
bumped.
Moving the assignment to l2tp_session_register is trivial but
l2tp_session_create calls l2tp_session_set_header_len which uses
session->tunnel to get the tunnel's encap. Add an encap arg to
l2tp_session_set_header_len to avoid using session->tunnel.
If l2tpv3 sessions have colliding IDs, it is possible for
l2tp_v3_session_get to race with l2tp_session_register and fetch a
session which doesn't yet have session->tunnel set. Add a check for
this case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: tcp_rtx_synack() can be called from process context
Laurent reported the enclosed report [1]
This bug triggers with following coditions:
0) Kernel built with CONFIG_DEBUG_PREEMPT=y
1) A new passive FastOpen TCP socket is created.
This FO socket waits for an ACK coming from client to be a complete
ESTABLISHED one.
2) A socket operation on this socket goes through lock_sock()
release_sock() dance.
3) While the socket is owned by the user in step 2),
a retransmit of the SYN is received and stored in socket backlog.
4) At release_sock() time, the socket backlog is processed while
in process context.
5) A SYNACK packet is cooked in response of the SYN retransmit.
6) -> tcp_rtx_synack() is called in process context.
Before blamed commit, tcp_rtx_synack() was always called from BH handler,
from a timer handler.
Fix this by using TCP_INC_STATS() & NET_INC_STATS()
which do not assume caller is in non preemptible context.

Bluetooth: hci_uart: add missing NULL check in h5_enqueue
Syzbot hit general protection fault in __pm_runtime_resume(). The problem
was in missing NULL check.
hu->serdev can be NULL and we should not blindly pass &serdev->dev
somewhere, since it will cause GPF.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix sleeping function called from invalid context on RT kernel
When setting bootparams="trace_event=initcall:initcall_start tp_printk=1" in the
cmdline, the output_printk() was called, and the spin_lock_irqsave() was called in the
atomic and irq disable interrupt context suitation. On the PREEMPT_RT kernel,
these locks are replaced with sleepable rt-spinlock, so the stack calltrace will
be triggered.
Fix it by raw_spin_lock_irqsave when PREEMPT_RT and "trace_event=initcall:initcall_start
tp_printk=1" enabled.
BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:46
in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 1, name: swapper/0
preempt_count: 2, expected: 0

---[ end trace 0000000000000000 ]---
Its possible that two threads call tcp_v6_do_rcv()/sk_forward_alloc_add()
concurrently when sk->sk_state == TCP_LISTEN with sk->sk_lock unlocked,
which triggers a data-race around sk->sk_forward_alloc:
tcp_v6_rcv
tcp_v6_do_rcv
skb_clone_and_charge_r
sk_rmem_schedule
__sk_mem_schedule
sk_forward_alloc_add()
skb_set_owner_r
sk_mem_charge
sk_forward_alloc_add()
__kfree_skb
skb_release_all
skb_release_head_state
sock_rfree
sk_mem_uncharge
sk_forward_alloc_add()
sk_mem_reclaim
// set local var reclaimable
__sk_mem_reclaim
sk_forward_alloc_add()
In this syzkaller testcase, two threads call
tcp_v6_do_rcv() with skb->truesize=768, the sk_forward_alloc changes like
this:
(cpu 1) | (cpu 2) | sk_forward_alloc
... | ... | 0
__sk_mem_schedule() | | +4096 = 4096
| __sk_mem_schedule() | +4096 = 8192
sk_mem_charge() | | -768 = 7424
| sk_mem_charge() | -768 = 6656
... | ... |
sk_mem_uncharge() | | +768 = 7424
reclaimable=7424 | |
| sk_mem_uncharge() | +768 = 8192
| reclaimable=8192 |
__sk_mem_reclaim() | | -4096 = 4096
| __sk_mem_reclaim() | -8192 = -4096 != 0
The skb_clone_and_charge_r() should not be called in tcp_v6_do_rcv() when
sk->sk_state is TCP_LISTEN, it happens later in tcp_v6_syn_recv_sock().
Fix the same issue in dccp_v6_do_rcv().

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: uvc: fix list double add in uvcg_video_pump
A panic can occur if the endpoint becomes disabled and the
uvcg_video_pump adds the request back to the req_free list after it has
already been queued to the endpoint. The endpoint complete will add the
request back to the req_free list. Invalidate the local request handle
once it's been queued.

"qemu-ndb -d" will call ioctl 'NBD_DISCONNECT' first, however, following
message was found:
block nbd0: Send disconnect failed -32
Which indicate that something is wrong with the server. Then,
"qemu-nbd -d" will call ioctl 'NBD_CLEAR_SOCK', however ioctl can't clear
requests after commit 2516ab1543fd("nbd: only clear the queue on device
teardown"). And in the meantime, request can't complete through timeout
because nbd_xmit_timeout() will always return 'BLK_EH_RESET_TIMER', which
means such request will never be completed in this situation.
Now that the flag 'NBD_CMD_INFLIGHT' can make sure requests won't
complete multiple times, switch back to call nbd_clear_sock() in
nbd_clear_sock_ioctl(), so that inflight requests can be cleared.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Check for potential null return of kmalloc_array()
As the kmalloc_array() may return null, the 'event_waiters[i].wait' would lead to null-pointer dereference.
Therefore, it is better to check the return value of kmalloc_array() to avoid this confusion.

Summary
In the Linux kernel, the following vulnerability has been resolved:
geneve: Fix use-after-free in geneve_find_dev().
syzkaller reported a use-after-free in geneve_find_dev() [0]
without repro.
geneve_configure() links struct geneve_dev.next to
net_generic(net, geneve_net_id)->geneve_list.
The net here could differ from dev_net(dev) if IFLA_NET_NS_PID,
IFLA_NET_NS_FD, or IFLA_TARGET_NETNSID is set.
When dev_net(dev) is dismantled, geneve_exit_batch_rtnl() finally
calls unregister_netdevice_queue() for each dev in the netns,
and later the dev is freed.
However, its geneve_dev.next is still linked to the backend UDP
socket netns.
Then, use-after-free will occur when another geneve dev is created
in the netns.
Let's call geneve_dellink() instead in geneve_destroy_tunnels().

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: fix rq-qos breakage from skipping rq_qos_done_bio()
a647a524a467 ("block: don't call rq_qos_ops->done_bio if the bio isn't
tracked") made bio_endio() skip rq_qos_done_bio() if BIO_TRACKED is not set.
While this fixed a potential oops, it also broke blk-iocost by skipping the
done_bio callback for merged bios.
Before, whether a bio goes through rq_qos_throttle() or rq_qos_merge(),
rq_qos_done_bio() would be called on the bio on completion with BIO_TRACKED
distinguishing the former from the latter. rq_qos_done_bio() is not called
for bios which wenth through rq_qos_merge(). This royally confuses
blk-iocost as the merged bios never finish and are considered perpetually
in-flight.
One reliably reproducible failure mode is an intermediate cgroup geting
stuck active preventing its children from being activated due to the
leaf-only rule, leading to loss of control. The following is from
resctl-bench protection scenario which emulates isolating a web server like
workload from a memory bomb run on an iocost configuration which should
yield a reasonable level of protection.

Result: isol=58.12:15.82% lat_imp=53.88%:143.6 work_csv=100.0% missing=3.96%
The isolation result of 58.12% is close to what this device would show
without any IO control.
Fix it by introducing a new flag BIO_QOS_MERGED to mark merged bios and
calling rq_qos_done_bio() on them too. For consistency and clarity, rename
BIO_TRACKED to BIO_QOS_THROTTLED. The flag checks are moved into
rq_qos_done_bio() so that it's next to the code paths that set the flags.
With the patch applied, the above same benchmark shows:
# resctl-bench -m 29.6G -r out.json run protection::scenario=mem-hog,loops=1

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSv4: Don't hold the layoutget locks across multiple RPC calls
When doing layoutget as part of the open() compound, we have to be
careful to release the layout locks before we can call any further RPC
calls, such as setattr(). The reason is that those calls could trigger
a recall, which could deadlock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic/realview: Fix refcount leak in realview_gic_of_init
of_find_matching_node_and_match() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: svm range restore work deadlock when process exit
kfd_process_notifier_release flush svm_range_restore_work
which calls svm_range_list_lock_and_flush_work to flush deferred_list
work, but if deferred_list work mmput release the last user, it will
call exit_mmap -> notifier_release, it is deadlock with below backtrace.
Move flush svm_range_restore_work to kfd_process_wq_release to avoid
deadlock. Then svm_range_restore_work take task->mm ref to avoid mm is
gone while validating and mapping ranges to GPU.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix warning in ext4_handle_inode_extension
We got issue as follows:

Above issue may happen as follows:
Assume
inode.i_size=4096
EXT4_I(inode)->i_disksize=4096
step 1: set inode->i_isize = 8192
ext4_setattr
if (attr->ia_size != inode->i_size)
EXT4_I(inode)->i_disksize = attr->ia_size;
rc = ext4_mark_inode_dirty
ext4_reserve_inode_write
ext4_get_inode_loc
__ext4_get_inode_loc
sb_getblk --> return -ENOMEM
...
if (!error) ->will not update i_size
i_size_write(inode, attr->ia_size);
Now:
inode.i_size=4096
EXT4_I(inode)->i_disksize=8192
step 2: Direct write 4096 bytes
ext4_file_write_iter
ext4_dio_write_iter
iomap_dio_rw ->return error
if (extend)
ext4_handle_inode_extension
WARN_ON_ONCE(i_size_read(inode) < EXT4_I(inode)->i_disksize);
->Then trigger warning.
To solve above issue, if mark inode dirty failed in ext4_setattr just
set 'EXT4_I(inode)->i_disksize' with old value.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/omap: Fix regression in probe for NULL pointer dereference
Commit 3f6634d997db ("iommu: Use right way to retrieve iommu_ops") started
triggering a NULL pointer dereference for some omap variants:
__iommu_probe_device from probe_iommu_group+0x2c/0x38
probe_iommu_group from bus_for_each_dev+0x74/0xbc
bus_for_each_dev from bus_iommu_probe+0x34/0x2e8
bus_iommu_probe from bus_set_iommu+0x80/0xc8
bus_set_iommu from omap_iommu_init+0x88/0xcc
omap_iommu_init from do_one_initcall+0x44/0x24
This is caused by omap iommu probe returning 0 instead of ERR_PTR(-ENODEV)
as noted by Jason Gunthorpe <jgg@ziepe.ca>.
Looks like the regression already happened with an earlier commit
6785eb9105e3 ("iommu/omap: Convert to probe/release_device() call-backs")
that changed the function return type and missed converting one place.

Reason is first directory entry which 'rec_len' is 34478, then will get illegal
parent entry. Now, we do not check directory entry after read directory block
in 'ext4_get_first_dir_block'.
To solve this issue, check directory entry in 'ext4_get_first_dir_block'.
[ Trigger an ext4_error() instead of just warning if the directory is
missing a '.' or '..' entry. Also make sure we return an error code
if the file system is corrupted. -TYT ]

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing/histograms: Fix memory leak problem
This reverts commit 46bbe5c671e06f070428b9be142cc4ee5cedebac.
As commit 46bbe5c671e0 ("tracing: fix double free") said, the
"double free" problem reported by clang static analyzer is:
> In parse_var_defs() if there is a problem allocating
> var_defs.expr, the earlier var_defs.name is freed.
> This free is duplicated by free_var_defs() which frees
> the rest of the list.
However, if there is a problem allocating N-th var_defs.expr:
+ in parse_var_defs(), the freed 'earlier var_defs.name' is
actually the N-th var_defs.name;
+ then in free_var_defs(), the names from 0th to (N-1)-th are freed;
IF ALLOCATING PROBLEM HAPPENED HERE!!! -+
\
|
0th 1th (N-1)-th N-th V
+-------------+-------------+-----+-------------+-----------
var_defs: | name | expr | name | expr | ... | name | expr | name | ///
+-------------+-------------+-----+-------------+-----------
These two frees don't act on same name, so there was no "double free"
problem before. Conversely, after that commit, we get a "memory leak"
problem because the above "N-th var_defs.name" is not freed.
If enable CONFIG_DEBUG_KMEMLEAK and inject a fault at where the N-th
var_defs.expr allocated, then execute on shell like:
$ echo 'hist:key=call_site:val=$v1,$v2:v1=bytes_req,v2=bytes_alloc' > \
/sys/kernel/debug/tracing/events/kmem/kmalloc/trigger
Then kmemleak reports:
unreferenced object 0xffff8fb100ef3518 (size 8):
comm "bash", pid 196, jiffies 4295681690 (age 28.538s)

We encountered a kernel panic issue that callback data will be NULL when
it's using in ovl irq handler. There is a timing issue between
mtk_disp_ovl_irq_handler() and mtk_ovl_disable_vblank().
To resolve this issue, we use the flow to register/unregister vblank cb:
- Register callback function and callback data when crtc creates.
- Unregister callback function and callback data when crtc destroies.
With this solution, we can assure callback data will not be NULL when
vblank is disable.

Summary
In the Linux kernel, the following vulnerability has been resolved:
firewire: fix memory leak for payload of request subaction to IEC 61883-1 FCP region
This patch is fix for Linux kernel v2.6.33 or later.
For request subaction to IEC 61883-1 FCP region, Linux FireWire subsystem
have had an issue of use-after-free. The subsystem allows multiple
user space listeners to the region, while data of the payload was likely
released before the listeners execute read(2) to access to it for copying
to user space.
The issue was fixed by a commit 281e20323ab7 ("firewire: core: fix
use-after-free regression in FCP handler"). The object of payload is
duplicated in kernel space for each listener. When the listener executes
ioctl(2) with FW_CDEV_IOC_SEND_RESPONSE request, the object is going to
be released.
However, it causes memory leak since the commit relies on call of
release_request() in drivers/firewire/core-cdev.c. Against the
expectation, the function is never called due to the design of
release_client_resource(). The function delegates release task
to caller when called with non-NULL fourth argument. The implementation
of ioctl_send_response() is the case. It should release the object
explicitly.
This commit fixes the bug.

The subsystem allows multiple\nuser space listeners to the region, while data of the payload was likely\nreleased before the listeners execute read(2) to access to it for copying\nto user space.\n\nThe issue was fixed by a commit 281e20323ab7 (\"firewire: core: fix\nuse-after-free regression in FCP handler\"). The object of payload is\nduplicated in kernel space for each listener. When the listener executes\nioctl(2) with FW_CDEV_IOC_SEND_RESPONSE request, the object is going to\nbe released.\n\nHowever, it causes memory leak since the commit relies on call of\nrelease_request() in drivers/firewire/core-cdev.c. Against the\nexpectation, the function is never called due to the design of\nrelease_client_resource(). The function delegates release task\nto caller when called with non-NULL fourth argument. The implementation\nof ioctl_send_response() is the case. It should release the object\nexplicitly.\n\nThis commit fixes the bug."

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm: fix use-after-free in dm_cleanup_zoned_dev()
dm_cleanup_zoned_dev() uses queue, so it must be called
before blk_cleanup_disk() starts its killing:
blk_cleanup_disk->blk_cleanup_queue()->kobject_put()->blk_release_queue()->
->...RCU...->blk_free_queue_rcu()->kmem_cache_free()
Otherwise, RCU callback may be executed first and
dm_cleanup_zoned_dev() will touch free'd memory:

Summary
In the Linux kernel, the following vulnerability has been resolved:
perf/x86/amd: fix potential integer overflow on shift of a int
The left shift of int 32 bit integer constant 1 is evaluated using 32 bit
arithmetic and then passed as a 64 bit function argument. In the case where
i is 32 or more this can lead to an overflow. Avoid this by shifting
using the BIT_ULL macro instead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ath10k: Fix error handling in ath10k_setup_msa_resources
The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
This function only calls of_node_put() in the regular path.
And it will cause refcount leak in error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix qgroup reserve overflow the qgroup limit
We use extent_changeset->bytes_changed in qgroup_reserve_data() to record
how many bytes we set for EXTENT_QGROUP_RESERVED state. Currently the
bytes_changed is set as "unsigned int", and it will overflow if we try to
fallocate a range larger than 4GiB. The result is we reserve less bytes
and eventually break the qgroup limit.
Unlike regular buffered/direct write, which we use one changeset for
each ordered extent, which can never be larger than 256M. For
fallocate, we use one changeset for the whole range, thus it no longer
respects the 256M per extent limit, and caused the problem.
The following example test script reproduces the problem:
$ cat qgroup-overflow.sh
#!/bin/bash
DEV=/dev/sdj
MNT=/mnt/sdj
mkfs.btrfs -f $DEV
mount $DEV $MNT
# Set qgroup limit to 2GiB.
btrfs quota enable $MNT
btrfs qgroup limit 2G $MNT
# Try to fallocate a 3GiB file. This should fail.
echo
echo "Try to fallocate a 3GiB file..."
fallocate -l 3G $MNT/3G.file
# Try to fallocate a 5GiB file.
echo
echo "Try to fallocate a 5GiB file..."
fallocate -l 5G $MNT/5G.file
# See we break the qgroup limit.
echo
sync
btrfs qgroup show -r $MNT
umount $MNT
When running the test:
$ ./qgroup-overflow.sh
(...)
Try to fallocate a 3GiB file...
fallocate: fallocate failed: Disk quota exceeded
Try to fallocate a 5GiB file...
qgroupid rfer excl max_rfer
-------- ---- ---- --------
0/5 5.00GiB 5.00GiB 2.00GiB
Since we have no control of how bytes_changed is used, it's better to
set it to u64.

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: Fix clk_hw_get_clk() when dev is NULL
Any registered clk_core structure can have a NULL pointer in its dev
field. While never actually documented, this is evidenced by the wide
usage of clk_register and clk_hw_register with a NULL device pointer,
and the fact that the core of_clk_hw_register() function also passes a
NULL device pointer.
A call to clk_hw_get_clk() on a clk_hw struct whose clk_core is in that
case will result in a NULL pointer derefence when it calls dev_name() on
that NULL device pointer.
Add a test for this case and use NULL as the dev_id if the device
pointer is NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ath11k: mhi: use mhi_sync_power_up()
If amss.bin was missing ath11k would crash during 'rmmod ath11k_pci'. The
reason for that was that we were using mhi_async_power_up() which does not
check any errors. But mhi_sync_power_up() on the other hand does check for
errors so let's use that to fix the crash.
I was not able to find a reason why an async version was used.
ath11k_mhi_start() (which enables state ATH11K_MHI_POWER_ON) is called from
ath11k_hif_power_up(), which can sleep. So sync version should be safe to use
here.

So sync version should be safe to use\nhere.\n\n[ 145.569731] general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] PREEMPT SMP DEBUG_PAGEALLOC KASAN PTI\n[ 145.569789] KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]\n[ 145.569843] CPU: 2 PID: 1628 Comm: rmmod Kdump: loaded Tainted: G W 5.16.0-wt-ath+ #567\n[ 145.569898] Hardware name: Intel(R) Client Systems NUC8i7HVK/NUC8i7HVB, BIOS HNKBLi70.86A.0067.2021.0528.1339 05/28/2021\n[ 145.569956] RIP: 0010:ath11k_hal_srng_access_begin+0xb5/0x2b0 [ath11k]\n[ 145.570028] Code: df 48 89 fa 48 c1 ea 03 80 3c 02 00 0f 85 ec 01 00 00 48 8b ab a8 00 00 00 48 b8 00 00 00 00 00 fc ff df 48 89 ea 48 c1 ea 03 \u003c0f\u003e b6 14 02 48 89 e8 83 e0 07 83 c0 03 45 85 ed 75 48 38 d0 7c 08\n[ 145.570089] RSP: 0018:ffffc900025d7ac0 EFLAGS: 00010246\n[ 145.570144] RAX: dffffc0000000000 RBX: ffff88814fca2dd8 RCX: 1ffffffff50cb455\n[ 145.570196] RDX: 0000000000000000 RSI: ffff88814fca2dd8 RDI: ffff88814fca2e80\n[ 145.570252] RBP: 0000000000000000 R08: 0000000000000000 R09: ffffffffa8659497\n[ 145.570329] R10: fffffbfff50cb292 R11: 0000000000000001 R12: ffff88814fca0000\n[ 145.570410] R13: 0000000000000000 R14: ffff88814fca2798 R15: ffff88814fca2dd8\n[ 145.570465] FS: 00007fa399988540(0000) GS:ffff888233e00000(0000) knlGS:0000000000000000\n[ 145.570519] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[ 145.570571] CR2: 00007fa399b51421 CR3: 0000000137898002 CR4: 00000000003706e0\n[ 145.570623] Call Trace:\n[ 145.570675] \u003cTASK\u003e\n[ 145.570727] ? ath11k_ce_tx_process_cb+0x34b/0x860 [ath11k]\n[ 145.570797] ath11k_ce_tx_process_cb+0x356/0x860 [ath11k]\n[ 145.570864] ? tasklet_init+0x150/0x150\n[ 145.570919] ? ath11k_ce_alloc_pipes+0x280/0x280 [ath11k]\n[ 145.570986] ? tasklet_clear_sched+0x42/0xe0\n[ 145.571042] ? tasklet_kill+0xe9/0x1b0\n[ 145.571095] ? tasklet_clear_sched+0xe0/0xe0\n[ 145.571148] ? irq_has_action+0x120/0x120\n[ 145.571202] ath11k_ce_cleanup_pipes+0x45a/0x580 [ath11k]\n[ 145.571270] ? ath11k_pci_stop+0x10e/0x170 [ath11k_pci]\n[ 145.571345] ath11k_core_stop+0x8a/0xc0 [ath11k]\n[ 145.571434] ath11k_core_deinit+0x9e/0x150 [ath11k]\n[ 145.571499] ath11k_pci_remove+0xd2/0x260 [ath11k_pci]\n[ 145.571553] pci_device_remove+0x9a/0x1c0\n[ 145.571605] __device_release_driver+0x332/0x660\n[ 145.571659] driver_detach+0x1e7/0x2c0\n[ 145.571712] bus_remove_driver+0xe2/0x2d0\n[ 145.571772] pci_unregister_driver+0x21/0x250\n[ 145.571826] __do_sys_delete_module+0x30a/0x4b0\n[ 145.571879] ? free_module+0xac0/0xac0\n[ 145.571933] ? lockdep_hardirqs_on_prepare.part.0+0x18c/0x370\n[ 145.571986] ? syscall_enter_from_user_mode+0x1d/0x50\n[ 145.572039] ? lockdep_hardirqs_on+0x79/0x100\n[ 145.572097] do_syscall_64+0x3b/0x90\n[ 145.572153] entry_SYSCALL_64_after_hwframe+0x44/0xae\n\nTested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03003-QCAHSPSWPL_V1_V2_SILICONZ_LITE-2"

Summary
In the Linux kernel, the following vulnerability has been resolved:
clocksource: hyper-v: unexport __init-annotated hv_init_clocksource()
EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.
modpost used to detect it, but it has been broken for a decade.
Recently, I fixed modpost so it started to warn it again, then this
showed up in linux-next builds.
There are two ways to fix it:
- Remove __init
- Remove EXPORT_SYMBOL
I chose the latter for this case because the only in-tree call-site,
arch/x86/kernel/cpu/mshyperv.c is never compiled as modular.
(CONFIG_HYPERVISOR_GUEST is boolean)

--------------------------------------------
Therefore, we should call jffs2_sum_reset_collected(s) on exit to
release the memory added in s. In addition, a new tag "out_buf" is
added to prevent the NULL pointer reference caused by s being NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: fix kernel panic caused by race of smc_sock
A crash occurs when smc_cdc_tx_handler() tries to access smc_sock
but smc_release() has already freed it.
[ 4570.695099] BUG: unable to handle page fault for address: 000000002eae9e88
[ 4570.696048] #PF: supervisor write access in kernel mode

[ 4570.714934] common_interrupt+0xba/0xe0
Though smc_cdc_tx_handler() checked the existence of smc connection,
smc_release() may have already dismissed and released the smc socket
before smc_cdc_tx_handler() further visits it.
smc_cdc_tx_handler() |smc_release()
if (!conn) |
|
|smc_cdc_tx_dismiss_slots()
| smc_cdc_tx_dismisser()
|
|sock_put(&smc->sk) <- last sock_put,
| smc_sock freed
bh_lock_sock(&smc->sk) (panic) |
To make sure we won't receive any CDC messages after we free the
smc_sock, add a refcount on the smc_connection for inflight CDC
message(posted to the QP but haven't received related CQE), and
don't release the smc_connection until all the inflight CDC messages
haven been done, for both success or failed ones.
Using refcount on CDC messages brings another problem: when the link
is going to be destroyed, smcr_link_clear() will reset the QP, which
then remove all the pending CQEs related to the QP in the CQ. To make
sure all the CQEs will always come back so the refcount on the
smc_connection can always reach 0, smc_ib_modify_qp_reset() was replaced
by smc_ib_modify_qp_error().
And remove the timeout in smc_wr_tx_wait_no_pending_sends() since we
need to wait for all pending WQEs done, or we may encounter use-after-
free when handling CQEs.
For IB device removal routine, we need to wait for all the QPs on that
device been destroyed before we can destroy CQs on the device, or
the refcount on smc_connection won't reach 0 and smc_sock cannot be
released.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mt76: fix monitor mode crash with sdio driver
mt7921s driver may receive frames with fragment buffers. If there is a
CTS packet received in monitor mode, the payload is 10 bytes only and
need 6 bytes header padding after RXD buffer. However, only RXD in the
first linear buffer, if we pull buffer size RXD-size+6 bytes with
skb_pull(), that would trigger "BUG_ON(skb->len < skb->data_len)" in
__skb_pull().
To avoid the nonlinear buffer issue, enlarge the RXD size from 128 to
256 to make sure all MCU operation in linear buffer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers: ethernet: cpsw: fix panic when interrupt coaleceing is set via ethtool
cpsw_ethtool_begin directly returns the result of pm_runtime_get_sync
when successful.
pm_runtime_get_sync returns -error code on failure and 0 on successful
resume but also 1 when the device is already active. So the common case
for cpsw_ethtool_begin is to return 1. That leads to inconsistent calls
to pm_runtime_put in the call-chain so that pm_runtime_put is called
one too many times and as result leaving the cpsw dev behind suspended.
The suspended cpsw dev leads to an access violation later on by
different parts of the cpsw driver.
Fix this by calling the return-friendly pm_runtime_resume_and_get
function.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/tm: Fix more userspace r13 corruption
Commit cf13435b730a ("powerpc/tm: Fix userspace r13 corruption") fixes a
problem in treclaim where a SLB miss can occur on the
thread_struct->ckpt_regs while SCRATCH0 is live with the saved user r13
value, clobbering it with the kernel r13 and ultimately resulting in
kernel r13 being stored in ckpt_regs.
There is an equivalent problem in trechkpt where the user r13 value is
loaded into r13 from chkpt_regs to be recheckpointed, but a SLB miss
could occur on ckpt_regs accesses after that, which will result in r13
being clobbered with a kernel value and that will get recheckpointed and
then restored to user registers.
The same memory page is accessed right before this critical window where
a SLB miss could cause corruption, so hitting the bug requires the SLB
entry be removed within a small window of instructions, which is
possible if a SLB related MCE hits there. PAPR also permits the
hypervisor to discard this SLB entry (because slb_shadow->persistent is
only set to SLB_NUM_BOLTED) although it's not known whether any
implementations would do this (KVM does not). So this is an extremely
unlikely bug, only found by inspection.
Fix this by also storing user r13 in a temporary location on the kernel
stack and don't change the r13 register from kernel r13 until the RI=0
critical section that does not fault.
The SCRATCH0 change is not strictly part of the fix, it's only used in
the RI=0 section so it does not have the same problem as the previous
SCRATCH0 bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: fix tcp_mtup_probe_success vs wrong snd_cwnd
syzbot got a new report [1] finally pointing to a very old bug,
added in initial support for MTU probing.
tcp_mtu_probe() has checks about starting an MTU probe if
tcp_snd_cwnd(tp) >= 11.
But nothing prevents tcp_snd_cwnd(tp) to be reduced later
and before the MTU probe succeeds.
This bug would lead to potential zero-divides.
Debugging added in commit 40570375356c ("tcp: add accessors
to read/set tp->snd_cwnd") has paid off :)
While we are at it, address potential overflows in this code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/pm: fix double free in si_parse_power_table()
In function si_parse_power_table(), array adev->pm.dpm.ps and its member
is allocated. If the allocation of each member fails, the array itself
is freed and returned with an error code. However, the array is later
freed again in si_dpm_fini() function which is called when the function
returns an error.
This leads to potential double free of the array adev->pm.dpm.ps, as
well as leak of its array members, since the members are not freed in
the allocation function and the array is not nulled when freed.
In addition adev->pm.dpm.num_ps, which keeps track of the allocated
array member, is not updated until the member allocation is
successfully finished, this could also lead to either use after free,
or uninitialized variable access in si_dpm_fini().
Fix this by postponing the free of the array until si_dpm_fini() and
increment adev->pm.dpm.num_ps everytime the array member is allocated.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sfc: fix kernel panic when creating VF
When creating VFs a kernel panic can happen when calling to
efx_ef10_try_update_nic_stats_vf.
When releasing a DMA coherent buffer, sometimes, I don't know in what
specific circumstances, it has to unmap memory with vunmap. It is
disallowed to do that in IRQ context or with BH disabled. Otherwise, we
hit this line in vunmap, causing the crash:
BUG_ON(in_interrupt());
This patch reenables BH to release the buffer.
Log messages when the bug is hit:

Summary
In the Linux kernel, the following vulnerability has been resolved:
usbnet: gl620a: fix endpoint checking in genelink_bind()
Syzbot reports [1] a warning in usb_submit_urb() triggered by
inconsistencies between expected and actually present endpoints
in gl620a driver. Since genelink_bind() does not properly
verify whether specified eps are in fact provided by the device,
in this case, an artificially manufactured one, one may get a
mismatch.
Fix the issue by resorting to a usbnet utility function
usbnet_get_endpoints(), usually reserved for this very problem.
Check for endpoints and return early before proceeding further if
any are missing.
[1] Syzbot report:

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/panfrost: Job should reference MMU not file_priv
For a while now it's been allowed for a MMU context to outlive it's
corresponding panfrost_priv, however the job structure still references
panfrost_priv to get hold of the MMU context. If panfrost_priv has been
freed this is a use-after-free which I've been able to trigger resulting
in a splat.
To fix this, drop the reference to panfrost_priv in the job structure
and add a direct reference to the MMU structure which is what's actually
needed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
block, bfq: fix uaf for bfqq in bic_set_bfqq()
After commit 64dc8c732f5c ("block, bfq: fix possible uaf for 'bfqq->bic'"),
bic->bfqq will be accessed in bic_set_bfqq(), however, in some context
bic->bfqq will be freed, and bic_set_bfqq() is called with the freed
bic->bfqq.
Fix the problem by always freeing bfqq after bic_set_bfqq().

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: fix use-after-free in chanctx code
In ieee80211_vif_use_reserved_context(), when we have an
old context and the new context's replace_state is set to
IEEE80211_CHANCTX_REPLACE_NONE, we free the old context
in ieee80211_vif_use_reserved_reassign(). Therefore, we
cannot check the old_ctx anymore, so we should set it to
NULL after this point.
However, since the new_ctx replace state is clearly not
IEEE80211_CHANCTX_REPLACES_OTHER, we're not going to do
anything else in this function and can just return to
avoid accessing the freed old_ctx.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: jack: Access input_dev under mutex
It is possible when using ASoC that input_dev is unregistered while
calling snd_jack_report, which causes NULL pointer dereference.
In order to prevent this serialize access to input_dev using mutex lock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: ipq8074: fix PCI-E clock oops
Fix PCI-E clock related kernel oops that are caused by a missing clock
parent.
pcie0_rchng_clk_src has num_parents set to 2 but only one parent is
actually set via parent_hws, it should also have "XO" defined.
This will cause the kernel to panic on a NULL pointer in
clk_core_get_parent_by_index().
So, to fix this utilize clk_parent_data to provide gcc_xo_gpll0 parent
data.
Since there is already an existing static const char * const gcc_xo_gpll0[]
used to provide the same parents via parent_names convert those users to
clk_parent_data as well.
Without this earlycon is needed to even catch the OOPS as it will reset
the board before serial is initialized with the following:

Summary
In the Linux kernel, the following vulnerability has been resolved:
memory: samsung: exynos5422-dmc: Fix refcount leak in of_get_dram_timings
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
This function doesn't call of_node_put() in some error paths.
To unify the structure, Add put_node label and goto it on errors.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: Fix div-by-zero in l2cap_le_flowctl_init()
l2cap_le_flowctl_init() can cause both div-by-zero and an integer
overflow since hdev->le_mtu may not fall in the valid range.
Move MTU from hci_dev to hci_conn to validate MTU and stop the connection
process earlier if MTU is invalid.
Also, add a missing validation in read_buffer_size() and make it return
an error value if the validation fails.
Now hci_conn_add() returns ERR_PTR() as it can fail due to the both a
kzalloc failure and invalid MTU value.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sfc: add missing xdp queue reinitialization
After rx/tx ring buffer size is changed, kernel panic occurs when
it acts XDP_TX or XDP_REDIRECT.
When tx/rx ring buffer size is changed(ethtool -G), sfc driver
reallocates and reinitializes rx and tx queues and their buffer
(tx_queue->buffer).
But it misses reinitializing xdp queues(efx->xdp_tx_queues).
So, while it is acting XDP_TX or XDP_REDIRECT, it uses the uninitialized
tx_queue->buffer.
A new function efx_set_xdp_channels() is separated from efx_set_channels()
to handle only xdp queues.
Splat looks like:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: mediatek: mt8192-mt6359: Fix error handling in mt8192_mt6359_dev_probe
The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
This function only calls of_node_put() in the regular path.
And it will cause refcount leak in error paths.
Fix this by calling of_node_put() in error handling too.

Reason is mhi_deassert_dev_wake() from mhi_device_put() is called
but mhi_assert_dev_wake() from __mhi_device_get_sync() is not called
in progress of recovery. Commit 8e0559921f9a ("bus: mhi: core:
Skip device wake in error or shutdown state") add check for the
pm_state of mhi in __mhi_device_get_sync(), and the pm_state is not
the normal state untill recovery is completed, so it leads the
dev_wake is not 0 and above warning print in mhi_pm_disable_transition()
while checking mhi_cntrl->dev_wake.
Add check in ath11k_pci_write32()/ath11k_pci_read32() to skip call
mhi_device_put() if mhi_device_get_sync() does not really do wake,
then the warning gone.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cgroup: Use separate src/dst nodes when preloading css_sets for migration
Each cset (css_set) is pinned by its tasks. When we're moving tasks around
across csets for a migration, we need to hold the source and destination
csets to ensure that they don't go away while we're moving tasks about. This
is done by linking cset->mg_preload_node on either the
mgctx->preloaded_src_csets or mgctx->preloaded_dst_csets list. Using the
same cset->mg_preload_node for both the src and dst lists was deemed okay as
a cset can't be both the source and destination at the same time.
Unfortunately, this overloading becomes problematic when multiple tasks are
involved in a migration and some of them are identity noop migrations while
others are actually moving across cgroups. For example, this can happen with
the following sequence on cgroup1:
#1> mkdir -p /sys/fs/cgroup/misc/a/b
#2> echo $$ > /sys/fs/cgroup/misc/a/cgroup.procs
#3> RUN_A_COMMAND_WHICH_CREATES_MULTIPLE_THREADS &
#4> PID=$!
#5> echo $PID > /sys/fs/cgroup/misc/a/b/tasks
#6> echo $PID > /sys/fs/cgroup/misc/a/cgroup.procs
the process including the group leader back into a. In this final migration,
non-leader threads would be doing identity migration while the group leader
is doing an actual one.
After #3, let's say the whole process was in cset A, and that after #4, the
leader moves to cset B. Then, during #6, the following happens:
1. cgroup_migrate_add_src() is called on B for the leader.
2. cgroup_migrate_add_src() is called on A for the other threads.
3. cgroup_migrate_prepare_dst() is called. It scans the src list.
4. It notices that B wants to migrate to A, so it tries to A to the dst
list but realizes that its ->mg_preload_node is already busy.
5. and then it notices A wants to migrate to A as it's an identity
migration, it culls it by list_del_init()'ing its ->mg_preload_node and
putting references accordingly.
6. The rest of migration takes place with B on the src list but nothing on
the dst list.
This means that A isn't held while migration is in progress. If all tasks
leave A before the migration finishes and the incoming task pins it, the
cset will be destroyed leading to use-after-free.
This is caused by overloading cset->mg_preload_node for both src and dst
preload lists. We wanted to exclude the cset from the src list but ended up
inadvertently excluding it from the dst list too.
This patch fixes the issue by separating out cset->mg_preload_node into
->mg_src_preload_node and ->mg_dst_preload_node, so that the src and dst
preloadings don't interfere with each other.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncgroup: Use separate src/dst nodes when preloading css_sets for migration\n\nEach cset (css_set) is pinned by its tasks. When we\u0027re moving tasks around\nacross csets for a migration, we need to hold the source and destination\ncsets to ensure that they don\u0027t go away while we\u0027re moving tasks about. This\nis done by linking cset-\u003emg_preload_node on either the\nmgctx-\u003epreloaded_src_csets or mgctx-\u003epreloaded_dst_csets list. Using the\nsame cset-\u003emg_preload_node for both the src and dst lists was deemed okay as\na cset can\u0027t be both the source and destination at the same time.\n\nUnfortunately, this overloading becomes problematic when multiple tasks are\ninvolved in a migration and some of them are identity noop migrations while\nothers are actually moving across cgroups. For example, this can happen with\nthe following sequence on cgroup1:\n\n #1\u003e mkdir -p /sys/fs/cgroup/misc/a/b\n #2\u003e echo $$ \u003e /sys/fs/cgroup/misc/a/cgroup.procs\n #3\u003e RUN_A_COMMAND_WHICH_CREATES_MULTIPLE_THREADS \u0026\n #4\u003e PID=$!\n #5\u003e echo $PID \u003e /sys/fs/cgroup/misc/a/b/tasks\n #6\u003e echo $PID \u003e /sys/fs/cgroup/misc/a/cgroup.procs\n\nthe process including the group leader back into a. In this final migration,\nnon-leader threads would be doing identity migration while the group leader\nis doing an actual one.\n\nAfter #3, let\u0027s say the whole process was in cset A, and that after #4, the\nleader moves to cset B. Then, during #6, the following happens:\n\n 1. cgroup_migrate_add_src() is called on B for the leader.\n\n 2. cgroup_migrate_add_src() is called on A for the other threads.\n\n 3. cgroup_migrate_prepare_dst() is called. It scans the src list.\n\n 4. It notices that B wants to migrate to A, so it tries to A to the dst\n list but realizes that its -\u003emg_preload_node is already busy.\n\n 5. and then it notices A wants to migrate to A as it\u0027s an identity\n migration, it culls it by list_del_init()\u0027ing its -\u003emg_preload_node and\n putting references accordingly.\n\n 6. The rest of migration takes place with B on the src list but nothing on\n the dst list.\n\nThis means that A isn\u0027t held while migration is in progress. If all tasks\nleave A before the migration finishes and the incoming task pins it, the\ncset will be destroyed leading to use-after-free.\n\nThis is caused by overloading cset-\u003emg_preload_node for both src and dst\npreload lists. We wanted to exclude the cset from the src list but ended up\ninadvertently excluding it from the dst list too.\n\nThis patch fixes the issue by separating out cset-\u003emg_preload_node into\n-\u003emg_src_preload_node and -\u003emg_dst_preload_node, so that the src and dst\npreloadings don\u0027t interfere with each other."

Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: Don't leak cfid when reconnect races with open_cached_dir
open_cached_dir() may either race with the tcon reconnection even before
compound_send_recv() or directly trigger a reconnection via
SMB2_open_init() or SMB_query_info_init().
The reconnection process invokes invalidate_all_cached_dirs() via
cifs_mark_open_files_invalid(), which removes all cfids from the
cfids->entries list but doesn't drop a ref if has_lease isn't true. This
results in the currently-being-constructed cfid not being on the list,
but still having a refcount of 2. It leaks if returned from
open_cached_dir().
Fix this by setting cfid->has_lease when the ref is actually taken; the
cfid will not be used by other threads until it has a valid time.
Addresses these kmemleaks:

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Protect memory leak for NPIV ports sending PLOGI_RJT
There is a potential memory leak in lpfc_ignore_els_cmpl() and
lpfc_els_rsp_reject() that was allocated from NPIV PLOGI_RJT
(lpfc_rcv_plogi()'s login_mbox).
Check if cmdiocb->context_un.mbox was allocated in lpfc_ignore_els_cmpl(),
and then free it back to phba->mbox_mem_pool along with mbox->ctx_buf for
service parameters.
For lpfc_els_rsp_reject() failure, free both the ctx_buf for service
parameters and the login_mbox.

...followed by more symptoms of corruption, with similar stacks:
refcount_t: underflow; use-after-free.
kernel BUG at lib/list_debug.c:62!
Kernel panic - not syncing: Oops - BUG: Fatal exception
This happens because pps_device_destruct() frees the pps_device with the
embedded cdev immediately after calling cdev_del(), but, as the comment
above cdev_del() notes, fops for previously opened cdevs are still
callable even after cdev_del() returns. I think this bug has always
been there: I can't explain why it suddenly started happening every time
I reboot this particular board.
In commit d953e0e837e6 ("pps: Fix a use-after free bug when
unregistering a source."), George Spelvin suggested removing the
embedded cdev. That seems like the simplest way to fix this, so I've
implemented his suggestion, using __register_chrdev() with pps_idr
becoming the source of truth for which minor corresponds to which
device.
But now that pps_idr defines userspace visibility instead of cdev_add(),
we need to be sure the pps->dev refcount can't reach zero while
userspace can still find it again. So, the idr_remove() call moves to
pps_unregister_cdev(), and pps_idr now holds a reference to pps->dev.
pps_core: source serial1 got cdev (251:1)
<...>
pps pps1: removed
pps_core: unregistering pps1
pps_core: deallocating pps1

Summary
In the Linux kernel, the following vulnerability has been resolved:
qede: confirm skb is allocated before using
qede_build_skb() assumes build_skb() always works and goes straight
to skb_reserve(). However, build_skb() can fail under memory pressure.
This results in a kernel panic because the skb to reserve is NULL.
Add a check in case build_skb() failed to allocate and return NULL.
The NULL return is handled correctly in callers to qede_build_skb().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipvs: fix UB due to uninitialized stack access in ip_vs_protocol_init()
Under certain kernel configurations when building with Clang/LLVM, the
compiler does not generate a return or jump as the terminator
instruction for ip_vs_protocol_init(), triggering the following objtool
warning during build time:
vmlinux.o: warning: objtool: ip_vs_protocol_init() falls through to next function __initstub__kmod_ip_vs_rr__935_123_ip_vs_rr_init6()
At runtime, this either causes an oops when trying to load the ipvs
module or a boot-time panic if ipvs is built-in. This same issue has
been reported by the Intel kernel test robot previously.
Digging deeper into both LLVM and the kernel code reveals this to be a
undefined behavior problem. ip_vs_protocol_init() uses a on-stack buffer
of 64 chars to store the registered protocol names and leaves it
uninitialized after definition. The function calls strnlen() when
concatenating protocol names into the buffer. With CONFIG_FORTIFY_SOURCE
strnlen() performs an extra step to check whether the last byte of the
input char buffer is a null character (commit 3009f891bb9f ("fortify:
Allow strlen() and strnlen() to pass compile-time known lengths")).
This, together with possibly other configurations, cause the following
IR to be generated:
define hidden i32 @ip_vs_protocol_init() local_unnamed_addr #5 section ".init.text" align 16 !kcfi_type !29 {
%1 = alloca [64 x i8], align 16
...
14: ; preds = %11
%15 = getelementptr inbounds i8, ptr %1, i64 63
%16 = load i8, ptr %15, align 1
%17 = tail call i1 @llvm.is.constant.i8(i8 %16)
%18 = icmp eq i8 %16, 0
%19 = select i1 %17, i1 %18, i1 false
br i1 %19, label %20, label %23
20: ; preds = %14
%21 = call i64 @strlen(ptr noundef nonnull dereferenceable(1) %1) #23
...
23: ; preds = %14, %11, %20
%24 = call i64 @strnlen(ptr noundef nonnull dereferenceable(1) %1, i64 noundef 64) #24
...
}
The above code calculates the address of the last char in the buffer
(value %15) and then loads from it (value %16). Because the buffer is
never initialized, the LLVM GVN pass marks value %16 as undefined:
%13 = getelementptr inbounds i8, ptr %1, i64 63
br i1 undef, label %14, label %17
This gives later passes (SCCP, in particular) more DCE opportunities by
propagating the undef value further, and eventually removes everything
after the load on the uninitialized stack location:
define hidden i32 @ip_vs_protocol_init() local_unnamed_addr #0 section ".init.text" align 16 !kcfi_type !11 {
%1 = alloca [64 x i8], align 16
...
12: ; preds = %11
%13 = getelementptr inbounds i8, ptr %1, i64 63
unreachable
}
In this way, the generated native code will just fall through to the
next function, as LLVM does not generate any code for the unreachable IR
instruction and leaves the function without a terminator.
Zero the on-stack buffer to avoid this possible UB.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bfq: Avoid merging queues with different parents
It can happen that the parent of a bfqq changes between the moment we
decide two queues are worth to merge (and set bic->stable_merge_bfqq)
and the moment bfq_setup_merge() is called. This can happen e.g. because
the process submitted IO for a different cgroup and thus bfqq got
reparented. It can even happen that the bfqq we are merging with has
parent cgroup that is already offline and going to be destroyed in which
case the merge can lead to use-after-free issues such as:

Summary
In the Linux kernel, the following vulnerability has been resolved:
mt76: mt7921: fix kernel crash at mt7921_pci_remove
The crash log shown it is possible that mt7921_irq_handler is called while
devm_free_irq is being handled so mt76_free_device need to be postponed
until devm_free_irq is completed to solve the crash we free the mt76 device
too early.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: Explicitly verify target vCPU is online in kvm_get_vcpu()
Explicitly verify the target vCPU is fully online _prior_ to clamping the
index in kvm_get_vcpu(). If the index is "bad", the nospec clamping will
generate '0', i.e. KVM will return vCPU0 instead of NULL.
In practice, the bug is unlikely to cause problems, as it will only come
into play if userspace or the guest is buggy or misbehaving, e.g. KVM may
send interrupts to vCPU0 instead of dropping them on the floor.
However, returning vCPU0 when it shouldn't exist per online_vcpus is
problematic now that KVM uses an xarray for the vCPUs array, as KVM needs
to insert into the xarray before publishing the vCPU to userspace (see
commit c5b077549136 ("KVM: Convert the kvm->vcpus array to a xarray")),
i.e. before vCPU creation is guaranteed to succeed.
As a result, incorrectly providing access to vCPU0 will trigger a
use-after-free if vCPU0 is dereferenced and kvm_vm_ioctl_create_vcpu()
bails out of vCPU creation due to an error and frees vCPU0. Commit
afb2acb2e3a3 ("KVM: Fix vcpu_array[0] races") papered over that issue, but
in doing so introduced an unsolvable teardown conundrum. Preventing
accesses to vCPU0 before it's fully online will allow reverting commit
afb2acb2e3a3, without re-introducing the vcpu_array[0] UAF race.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Use __try_cmpxchg_user() to update guest PTE A/D bits
Use the recently introduced __try_cmpxchg_user() to update guest PTE A/D
bits instead of mapping the PTE into kernel address space. The VM_PFNMAP
path is broken as it assumes that vm_pgoff is the base pfn of the mapped
VMA range, which is conceptually wrong as vm_pgoff is the offset relative
to the file and has nothing to do with the pfn. The horrific hack worked
for the original use case (backing guest memory with /dev/mem), but leads
to accessing "random" pfns for pretty much any other VM_PFNMAP case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/iommu: Add missing of_node_put in iommu_init_early_dart
The device_node pointer is returned by of_find_compatible_node
with refcount incremented. We should use of_node_put() to avoid
the refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: mcba_usb: properly check endpoint type
Syzbot reported warning in usb_submit_urb() which is caused by wrong
endpoint type. We should check that in endpoint is actually present to
prevent this warning.
Found pipes are now saved to struct mcba_priv and code uses them
directly instead of making pipes in place.
Fail log:

Summary
In the Linux kernel, the following vulnerability has been resolved:
video: fbdev: smscufx: Fix null-ptr-deref in ufx_usb_probe()
I got a null-ptr-deref report:
BUG: kernel NULL pointer dereference, address: 0000000000000000
...
RIP: 0010:fb_destroy_modelist+0x38/0x100
...
Call Trace:
ufx_usb_probe.cold+0x2b5/0xac1 [smscufx]
usb_probe_interface+0x1aa/0x3c0 [usbcore]
really_probe+0x167/0x460
...
ret_from_fork+0x1f/0x30
If fb_alloc_cmap() fails in ufx_usb_probe(), fb_destroy_modelist() will
be called to destroy modelist in the error handling path. But modelist
has not been initialized yet, so it will result in null-ptr-deref.
Initialize modelist before calling fb_alloc_cmap() to fix this bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: rose: fix timer races against user threads
Rose timers only acquire the socket spinlock, without
checking if the socket is owned by one user thread.
Add a check and rearm the timers if needed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
exec: Force single empty string when argv is empty
Quoting[1] Ariadne Conill:
"In several other operating systems, it is a hard requirement that the
second argument to execve(2) be the name of a program, thus prohibiting
a scenario where argc < 1. POSIX 2017 also recommends this behaviour,
but it is not an explicit requirement[2]:
The argument arg0 should point to a filename string that is
associated with the process being started by one of the exec
functions.
...
Interestingly, Michael Kerrisk opened an issue about this in 2008[3],
but there was no consensus to support fixing this issue then.
Hopefully now that CVE-2021-4034 shows practical exploitative use[4]
of this bug in a shellcode, we can reconsider.
This issue is being tracked in the KSPP issue tracker[5]."
While the initial code searches[6][7] turned up what appeared to be
mostly corner case tests, trying to that just reject argv == NULL
(or an immediately terminated pointer list) quickly started tripping[8]
existing userspace programs.
The next best approach is forcing a single empty string into argv and
adjusting argc to match. The number of programs depending on argc == 0
seems a smaller set than those calling execve with a NULL argv.
Account for the additional stack space in bprm_stack_limits(). Inject an
empty string when argc == 0 (and set argc = 1). Warn about the case so
userspace has some notice about the change:
process './argc0' launched './argc0' with NULL argv: empty string added
Additionally WARN() and reject NULL argv usage for kernel threads.

POSIX 2017 also recommends this behaviour,\nbut it is not an explicit requirement[2]:\n\n The argument arg0 should point to a filename string that is\n associated with the process being started by one of the exec\n functions.\n...\nInterestingly, Michael Kerrisk opened an issue about this in 2008[3],\nbut there was no consensus to support fixing this issue then.\nHopefully now that CVE-2021-4034 shows practical exploitative use[4]\nof this bug in a shellcode, we can reconsider.\n\nThis issue is being tracked in the KSPP issue tracker[5].\"\n\nWhile the initial code searches[6][7] turned up what appeared to be\nmostly corner case tests, trying to that just reject argv == NULL\n(or an immediately terminated pointer list) quickly started tripping[8]\nexisting userspace programs.\n\nThe next best approach is forcing a single empty string into argv and\nadjusting argc to match. The number of programs depending on argc == 0\nseems a smaller set than those calling execve with a NULL argv.\n\nAccount for the additional stack space in bprm_stack_limits(). Inject an\nempty string when argc == 0 (and set argc = 1). Warn about the case so\nuserspace has some notice about the change:\n\n process \u0027./argc0\u0027 launched \u0027./argc0\u0027 with NULL argv: empty string added\n\nAdditionally WARN() and reject NULL argv usage for kernel threads.\n\n[1] https://lore.kernel.org/lkml/20220127000724.15106-1-ariadne@dereferenced.org/\n[2] https://pubs.opengroup.org/onlinepubs/9699919799/functions/exec.html\n[3] https://bugzilla.kernel.org/show_bug.cgi?id=8408\n[4] https://www.qualys.com/2022/01/25/cve-2021-4034/pwnkit.txt\n[5] https://github.com/KSPP/linux/issues/176\n[6] https://codesearch.debian.net/search?q=execve%5C+*%5C%28%5B%5E%2C%5D%2B%2C+*NULL\u0026literal=0\n[7] https://codesearch.debian.net/search?q=execlp%3F%5Cs*%5C%28%5B%5E%2C%5D%2B%2C%5Cs*NULL\u0026literal=0\n[8] https://lore.kernel.org/lkml/20220131144352.GE16385@xsang-OptiPlex-9020/"

Summary
In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v3: Fix error handling in gic_populate_ppi_partitions
of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
When kcalloc fails, it missing of_node_put() and results in refcount
leak. Fix this by goto out_put_node label.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/mdp5: Return error code in mdp5_pipe_release when deadlock is detected
mdp5_get_global_state runs the risk of hitting a -EDEADLK when acquiring
the modeset lock, but currently mdp5_pipe_release doesn't check for if
an error is returned. Because of this, there is a possibility of
mdp5_pipe_release hitting a NULL dereference error.
To avoid this, let's have mdp5_pipe_release check if
mdp5_get_global_state returns an error and propogate that error.
Changes since v1:
- Separated declaration and initialization of *new_state to avoid
compiler warning
- Fixed some spelling mistakes in commit message
Changes since v2:
- Return 0 in case where hwpipe is NULL as this is considered normal
behavior
- Added 2nd patch in series to fix a similar NULL dereference issue in
mdp5_mixer_release

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Fix list protocols enumeration in the base protocol
While enumerating protocols implemented by the SCMI platform using
BASE_DISCOVER_LIST_PROTOCOLS, the number of returned protocols is
currently validated in an improper way since the check employs a sum
between unsigned integers that could overflow and cause the check itself
to be silently bypassed if the returned value 'loop_num_ret' is big
enough.
Fix the validation avoiding the addition.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: venus: hfi: avoid null dereference in deinit
If venus_probe fails at pm_runtime_put_sync the error handling first
calls hfi_destroy and afterwards hfi_core_deinit. As hfi_destroy sets
core->ops to NULL, hfi_core_deinit cannot call the core_deinit function
anymore.
Avoid this null pointer derefence by skipping the call when necessary.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/hfi1: Prevent use of lock before it is initialized
If there is a failure during probe of hfi1 before the sdma_map_lock is
initialized, the call to hfi1_free_devdata() will attempt to use a lock
that has not been initialized. If the locking correctness validator is on
then an INFO message and stack trace resembling the following may be seen:
INFO: trying to register non-static key.
The code is fine but needs lockdep annotation, or maybe
you didn't initialize this object before use?
turning off the locking correctness validator.
Call Trace:
register_lock_class+0x11b/0x880
__lock_acquire+0xf3/0x7930
lock_acquire+0xff/0x2d0
_raw_spin_lock_irq+0x46/0x60
sdma_clean+0x42a/0x660 [hfi1]
hfi1_free_devdata+0x3a7/0x420 [hfi1]
init_one+0x867/0x11a0 [hfi1]
pci_device_probe+0x40e/0x8d0
The use of sdma_map_lock in sdma_clean() is for freeing the sdma_map
memory, and sdma_map is not allocated/initialized until after
sdma_map_lock has been initialized. This code only needs to be run if
sdma_map is not NULL, and so checking for that condition will avoid trying
to use the lock before it is initialized.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rdma/cxgb4: Prevent potential integer overflow on 32bit
The "gl->tot_len" variable is controlled by the user. It comes from
process_responses(). On 32bit systems, the "gl->tot_len + sizeof(struct
cpl_pass_accept_req) + sizeof(struct rss_header)" addition could have an
integer wrapping bug. Use size_add() to prevent this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rtl818x: Prevent using not initialized queues
Using not existing queues can panic the kernel with rtl8180/rtl8185 cards.
Ignore the skb priority for those cards, they only have one tx queue. Pierre
Asselin (pa@panix.com) reported the kernel crash in the Gentoo forum:
https://forums.gentoo.org/viewtopic-t-1147832-postdays-0-postorder-asc-start-25.html
He also confirmed that this patch fixes the issue. In summary this happened:
After updating wpa_supplicant from 2.9 to 2.10 the kernel crashed with a
"divide error: 0000" when connecting to an AP. Control port tx now tries to
use IEEE80211_AC_VO for the priority, which wpa_supplicants starts to use in
2.10.
Since only the rtl8187se part of the driver supports QoS, the priority
of the skb is set to IEEE80211_AC_BE (2) by mac80211 for rtl8180/rtl8185
cards.
rtl8180 is then unconditionally reading out the priority and finally crashes on
drivers/net/wireless/realtek/rtl818x/rtl8180/dev.c line 544 without this
patch:
idx = (ring->idx + skb_queue_len(&ring->queue)) % ring->entries
"ring->entries" is zero for rtl8180/rtl8185 cards, tx_ring[2] never got
initialized.

Summary
In the Linux kernel, the following vulnerability has been resolved:
filemap: Handle sibling entries in filemap_get_read_batch()
If a read races with an invalidation followed by another read, it is
possible for a folio to be replaced with a higher-order folio. If that
happens, we'll see a sibling entry for the new folio in the next iteration
of the loop. This manifests as a NULL pointer dereference while holding
the RCU read lock.
Handle this by simply returning. The next call will find the new folio
and handle it correctly. The other ways of handling this rare race are
more complex and it's just not worth it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm raid: fix KASAN warning in raid5_add_disks
There's a KASAN warning in raid5_add_disk when running the LVM testsuite.
The warning happens in the test
lvconvert-raid-reshape-linear_to_raid6-single-type.sh. We fix the warning
by verifying that rdev->saved_raid_disk is within limits.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/core: Fix ib block iterator counter overflow
When registering a new DMA MR after selecting the best aligned page size
for it, we iterate over the given sglist to split each entry to smaller,
aligned to the selected page size, DMA blocks.
In given circumstances where the sg entry and page size fit certain
sizes and the sg entry is not aligned to the selected page size, the
total size of the aligned pages we need to cover the sg entry is >= 4GB.
Under this circumstances, while iterating page aligned blocks, the
counter responsible for counting how much we advanced from the start of
the sg entry is overflowed because its type is u32 and we pass 4GB in
size. This can lead to an infinite loop inside the iterator function
because the overflow prevents the counter to be larger
than the size of the sg entry.
Fix the presented problem by changing the advancement condition to
eliminate overflow.

Summary
In the Linux kernel, the following vulnerability has been resolved:
soc: bcm: brcmstb: pm: pm-arm: Fix refcount leak in brcmstb_pm_probe
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
In brcmstb_init_sram, it pass dn to of_address_to_resource(),
of_address_to_resource() will call of_find_device_by_node() to take
reference, so we should release the reference returned by
of_find_matching_node().

Summary
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: Trap RDMA segment overflows
Prevent svc_rdma_build_writes() from walking off the end of a Write
chunk's segment array. Caught with KASAN.
The test that this fix replaces is invalid, and might have been left
over from an earlier prototype of the PCL work.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mtd: rawnand: cadence: fix possible null-ptr-deref in cadence_nand_dt_probe()
It will cause null-ptr-deref when using 'res', if platform_get_resource()
returns NULL, so move using 'res' after devm_ioremap_resource() that
will check it to avoid null-ptr-deref.
And use devm_platform_get_and_ioremap_resource() to simplify code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PM / devfreq: exynos-ppmu: Fix refcount leak in of_get_devfreq_events
of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
This function only calls of_node_put() in normal path,
missing it in error paths.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: disable the elevator int del_gendisk
The elevator is only used for file system requests, which are stopped in
del_gendisk. Move disabling the elevator and freeing the scheduler tags
to the end of del_gendisk instead of doing that work in disk_release and
blk_cleanup_queue to avoid a use after free on q->tag_set from
disk_release as the tag_set might not be alive at that point.
Move the blk_qos_exit call as well, as it just depends on the elevator
exit and would be the only reason to keep the not exactly cheap queue
freeze in disk_release.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Revert "Revert "block, bfq: honor already-setup queue merges""
A crash [1] happened to be triggered in conjunction with commit
2d52c58b9c9b ("block, bfq: honor already-setup queue merges"). The
latter was then reverted by commit ebc69e897e17 ("Revert "block, bfq:
honor already-setup queue merges""). Yet, the reverted commit was not
the one introducing the bug. In fact, it actually triggered a UAF
introduced by a different commit, and now fixed by commit d29bd41428cf

So, there is no point in keeping commit 2d52c58b9c9b ("block, bfq:
honor already-setup queue merges") out. This commit restores it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers: staging: rtl8192bs: Fix deadlock in rtw_joinbss_event_prehandle()
There is a deadlock in rtw_joinbss_event_prehandle(), which is shown
below:
(Thread 1) | (Thread 2)
| _set_timer()
rtw_joinbss_event_prehandle()| mod_timer()
spin_lock_bh() //(1) | (wait a time)
... | _rtw_join_timeout_handler()
del_timer_sync() | spin_lock_bh() //(2)
(wait timer to stop) | ...
We hold pmlmepriv->lock in position (1) of thread 1 and
use del_timer_sync() to wait timer to stop, but timer handler
also need pmlmepriv->lock in position (2) of thread 2.
As a result, rtw_joinbss_event_prehandle() will block forever.
This patch extracts del_timer_sync() from the protection of
spin_lock_bh(), which could let timer handler to obtain
the needed lock. What`s more, we change spin_lock_bh() to
spin_lock_irq() in _rtw_join_timeout_handler() in order to
prevent deadlock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: imx-sdma: Fix a possible memory leak in sdma_transfer_init
If the function sdma_load_context() fails, the sdma_desc will be
freed, but the allocated desc->bd is forgot to be freed.
We already met the sdma_load_context() failure case and the log as
below:
[ 450.699064] imx-sdma 30bd0000.dma-controller: Timeout waiting for CH0 ready
...
In this case, the desc->bd will not be freed without this change.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfc: nfcmrvl: Fix memory leak in nfcmrvl_play_deferred
Similar to the handling of play_deferred in commit 19cfe912c37b
("Bluetooth: btusb: Fix memory leak in play_deferred"), we thought
a patch might be needed here as well.
Currently usb_submit_urb is called directly to submit deferred tx
urbs after unanchor them.
So the usb_giveback_urb_bh would failed to unref it in usb_unanchor_urb
and cause memory leak.
Put those urbs in tx_anchor to avoid the leak, and also fix the error
handling.

Summary
In the Linux kernel, the following vulnerability has been resolved:
perf/core: Fix data race between perf_event_set_output() and perf_mmap_close()
Yang Jihing reported a race between perf_event_set_output() and
perf_mmap_close():
CPU1 CPU2
perf_mmap_close(e2)
if (atomic_dec_and_test(&e2->rb->mmap_count)) // 1 - > 0
detach_rest = true
ioctl(e1, IOC_SET_OUTPUT, e2)
perf_event_set_output(e1, e2)
...
list_for_each_entry_rcu(e, &e2->rb->event_list, rb_entry)
ring_buffer_attach(e, NULL);
// e1 isn't yet added and
// therefore not detached
ring_buffer_attach(e1, e2->rb)
list_add_rcu(&e1->rb_entry,
&e2->rb->event_list)
After this; e1 is attached to an unmapped rb and a subsequent
perf_mmap() will loop forever more:
again:
mutex_lock(&e->mmap_mutex);
if (event->rb) {
...
if (!atomic_inc_not_zero(&e->rb->mmap_count)) {
...
mutex_unlock(&e->mmap_mutex);
goto again;
}
}
The loop in perf_mmap_close() holds e2->mmap_mutex, while the attach
in perf_event_set_output() holds e1->mmap_mutex. As such there is no
serialization to avoid this race.
Change perf_event_set_output() to take both e1->mmap_mutex and
e2->mmap_mutex to alleviate that problem. Additionally, have the loop
in perf_mmap() detach the rb directly, this avoids having to wait for
the concurrent perf_mmap_close() to get around to doing it to make
progress.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ath9k_htc: fix potential out of bounds access with invalid rxstatus->rs_keyix
The "rxstatus->rs_keyix" eventually gets passed to test_bit() so we need to
ensure that it is within the bitmap.
drivers/net/wireless/ath/ath9k/common.c:46 ath9k_cmn_rx_accept()
error: passing untrusted data 'rx_stats->rs_keyix' to 'test_bit()'

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: gs_usb: gs_usb_open/close(): fix memory leak
The gs_usb driver appears to suffer from a malady common to many USB
CAN adapter drivers in that it performs usb_alloc_coherent() to
allocate a number of USB request blocks (URBs) for RX, and then later
relies on usb_kill_anchored_urbs() to free them, but this doesn't
actually free them. As a result, this may be leaking DMA memory that's
been used by the driver.
This commit is an adaptation of the techniques found in the esd_usb2
driver where a similar design pattern led to a memory leak. It
explicitly frees the RX URBs and their DMA memory via a call to
usb_free_coherent(). Since the RX URBs were allocated in the
gs_can_open(), we remove them in gs_can_close() rather than in the
disconnect function as was done in esd_usb2.
For more information, see the 928150fad41b ("can: esd_usb2: fix memory
leak").

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: don't delete queue kobject before its children
kobjects aren't supposed to be deleted before their child kobjects are
deleted. Apparently this is usually benign; however, a WARN will be
triggered if one of the child kobjects has a named attribute group:
sysfs group 'modes' not found for kobject 'crypto'
WARNING: CPU: 0 PID: 1 at fs/sysfs/group.c:278 sysfs_remove_group+0x72/0x80
...

Fix this by moving the kobject_del() and the corresponding
kobject_uevent() to the correct place.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm raid: fix accesses beyond end of raid member array
On dm-raid table load (using raid_ctr), dm-raid allocates an array
rs->devs[rs->raid_disks] for the raid device members. rs->raid_disks
is defined by the number of raid metadata and image tupples passed
into the target's constructor.
In the case of RAID layout changes being requested, that number can be
different from the current number of members for existing raid sets as
defined in their superblocks. Example RAID layout changes include:
- raid1 legs being added/removed
- raid4/5/6/10 number of stripes changed (stripe reshaping)
- takeover to higher raid level (e.g. raid5 -> raid6)
When accessing array members, rs->raid_disks must be used in control
loops instead of the potentially larger value in rs->md.raid_disks.
Otherwise it will cause memory access beyond the end of the rs->devs
array.
Fix this by changing code that is prone to out-of-bounds access.
Also fix validate_raid_redundancy() to validate all devices that are
added. Also, use braces to help clean up raid_iterate_devices().
The out-of-bounds memory accesses was discovered using KASAN.
This commit was verified to pass all LVM2 RAID tests (with KASAN
enabled).

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/bridge: Add missing pm_runtime_put_sync
pm_runtime_get_sync() will increase the rumtime PM counter
even when it returns an error. Thus a pairing decrement is needed
to prevent refcount leak. Fix this by replacing this API with
pm_runtime_resume_and_get(), which will not change the runtime
PM counter on error. Besides, a matching decrement is needed
on the error handling path to keep the counter balanced.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Drivers: hv: vmbus: Fix potential crash on module unload
The vmbus driver relies on the panic notifier infrastructure to perform
some operations when a panic event is detected. Since vmbus can be built
as module, it is required that the driver handles both registering and
unregistering such panic notifier callback.
After commit 74347a99e73a ("x86/Hyper-V: Unload vmbus channel in hv panic callback")
though, the panic notifier registration is done unconditionally in the module
initialization routine whereas the unregistering procedure is conditionally
guarded and executes only if HV_FEATURE_GUEST_CRASH_MSR_AVAILABLE capability
is set.
This patch fixes that by unconditionally unregistering the panic notifier
in the module's exit routine as well.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/slub: add missing TID updates on slab deactivation
The fastpath in slab_alloc_node() assumes that c->slab is stable as long as
the TID stays the same. However, two places in __slab_alloc() currently
don't update the TID when deactivating the CPU slab.
If multiple operations race the right way, this could lead to an object
getting lost; or, in an even more unlikely situation, it could even lead to
an object being freed onto the wrong slab's freelist, messing up the
`inuse` counter and eventually causing a page to be freed to the page
allocator while it still contains slab objects.
(I haven't actually tested these cases though, this is just based on
looking at the code. Writing testcases for this stuff seems like it'd be
a pain...)
The race leading to state inconsistency is (all operations on the same CPU
and kmem_cache):
- task A: begin do_slab_free():
- read TID
- read pcpu freelist (==NULL)
- check `slab == c->slab` (true)
- [PREEMPT A->B]
- task B: begin slab_alloc_node():
- fastpath fails (`c->freelist` is NULL)
- enter __slab_alloc()
- slub_get_cpu_ptr() (disables preemption)
- enter ___slab_alloc()
- take local_lock_irqsave()
- read c->freelist as NULL
- get_freelist() returns NULL
- write `c->slab = NULL`
- drop local_unlock_irqrestore()
- goto new_slab
- slub_percpu_partial() is NULL
- get_partial() returns NULL
- slub_put_cpu_ptr() (enables preemption)
- [PREEMPT B->A]
- task A: finish do_slab_free():
- this_cpu_cmpxchg_double() succeeds()
- [CORRUPT STATE: c->slab==NULL, c->freelist!=NULL]
From there, the object on c->freelist will get lost if task B is allowed to
continue from here: It will proceed to the retry_load_slab label,
set c->slab, then jump to load_freelist, which clobbers c->freelist.
But if we instead continue as follows, we get worse corruption:
- task A: run __slab_free() on object from other struct slab:
- CPU_PARTIAL_FREE case (slab was on no list, is now on pcpu partial)
- task A: run slab_alloc_node() with NUMA node constraint:
- fastpath fails (c->slab is NULL)
- call __slab_alloc()
- slub_get_cpu_ptr() (disables preemption)
- enter ___slab_alloc()
- c->slab is NULL: goto new_slab
- slub_percpu_partial() is non-NULL
- set c->slab to slub_percpu_partial(c)
- [CORRUPT STATE: c->slab points to slab-1, c->freelist has objects
from slab-2]
- goto redo
- node_match() fails
- goto deactivate_slab
- existing c->freelist is passed into deactivate_slab()
- inuse count of slab-1 is decremented to account for object from
slab-2
At this point, the inuse count of slab-1 is 1 lower than it should be.
This means that if we free all allocated objects in slab-1 except for one,
SLUB will think that slab-1 is completely unused, and may free its page,
leading to use-after-free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ubifs: rename_whiteout: Fix double free for whiteout_ui->data
'whiteout_ui->data' will be freed twice if space budget fail for
rename whiteout operation as following process:
rename_whiteout
dev = kmalloc

kfree(whiteout_ui->data) // Free first time
iput(whiteout)
ubifs_free_inode

assignment 'whiteout_ui->data_len = 0', process 'ubifs_evict_inode()
-> ubifs_jnl_delete_inode() -> ubifs_jnl_write_inode()' doesn't need it
(because 'inc_nlink(whiteout)' won't be excuted by 'goto out_release',
and the nlink of whiteout inode is 0).

Summary
In the Linux kernel, the following vulnerability has been resolved:
ath10k: skip ath10k_halt during suspend for driver state RESTARTING
Double free crash is observed when FW recovery(caused by wmi
timeout/crash) is followed by immediate suspend event. The FW recovery
is triggered by ath10k_core_restart() which calls driver clean up via
ath10k_halt(). When the suspend event occurs between the FW recovery,
the restart worker thread is put into frozen state until suspend completes.
The suspend event triggers ath10k_stop() which again triggers ath10k_halt()
The double invocation of ath10k_halt() causes ath10k_htt_rx_free() to be
called twice(Note: ath10k_htt_rx_alloc was not called by restart worker
thread because of its frozen state), causing the crash.
To fix this, during the suspend flow, skip call to ath10k_halt() in
ath10k_stop() when the current driver state is ATH10K_STATE_RESTARTING.
Also, for driver state ATH10K_STATE_RESTARTING, call
ath10k_wait_for_suspend() in ath10k_stop(). This is because call to
ath10k_wait_for_suspend() is skipped later in
[ath10k_halt() > ath10k_core_stop()] for the driver state
ATH10K_STATE_RESTARTING.
The frozen restart worker thread will be cancelled during resume when the
device comes out of suspend.

This is because call to\nath10k_wait_for_suspend() is skipped later in\n[ath10k_halt() \u003e ath10k_core_stop()] for the driver state\nATH10K_STATE_RESTARTING.\n\nThe frozen restart worker thread will be cancelled during resume when the\ndevice comes out of suspend.\n\nBelow is the crash stack for reference:\n\n[ 428.469167] ------------[ cut here ]------------\n[ 428.469180] kernel BUG at mm/slub.c:4150!\n[ 428.469193] invalid opcode: 0000 [#1] PREEMPT SMP NOPTI\n[ 428.469219] Workqueue: events_unbound async_run_entry_fn\n[ 428.469230] RIP: 0010:kfree+0x319/0x31b\n[ 428.469241] RSP: 0018:ffffa1fac015fc30 EFLAGS: 00010246\n[ 428.469247] RAX: ffffedb10419d108 RBX: ffff8c05262b0000\n[ 428.469252] RDX: ffff8c04a8c07000 RSI: 0000000000000000\n[ 428.469256] RBP: ffffa1fac015fc78 R08: 0000000000000000\n[ 428.469276] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[ 428.469285] Call Trace:\n[ 428.469295] ? dma_free_attrs+0x5f/0x7d\n[ 428.469320] ath10k_core_stop+0x5b/0x6f\n[ 428.469336] ath10k_halt+0x126/0x177\n[ 428.469352] ath10k_stop+0x41/0x7e\n[ 428.469387] drv_stop+0x88/0x10e\n[ 428.469410] __ieee80211_suspend+0x297/0x411\n[ 428.469441] rdev_suspend+0x6e/0xd0\n[ 428.469462] wiphy_suspend+0xb1/0x105\n[ 428.469483] ? name_show+0x2d/0x2d\n[ 428.469490] dpm_run_callback+0x8c/0x126\n[ 428.469511] ? name_show+0x2d/0x2d\n[ 428.469517] __device_suspend+0x2e7/0x41b\n[ 428.469523] async_suspend+0x1f/0x93\n[ 428.469529] async_run_entry_fn+0x3d/0xd1\n[ 428.469535] process_one_work+0x1b1/0x329\n[ 428.469541] worker_thread+0x213/0x372\n[ 428.469547] kthread+0x150/0x15f\n[ 428.469552] ? pr_cont_work+0x58/0x58\n[ 428.469558] ? kthread_blkcg+0x31/0x31\n\nTested-on: QCA6174 hw3.2 PCI WLAN.RM.4.4.1-00288-QCARMSWPZ-1"

Summary
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: aspeed: Fix potential NULL dereference in aspeed_pinmux_set_mux()
pdesc could be null but still dereference pdesc->name and it will lead to
a null pointer access. So we move a null check before dereference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: firewire-lib: fix uninitialized flag for AV/C deferred transaction
AV/C deferred transaction was supported at a commit 00a7bb81c20f ("ALSA:
firewire-lib: Add support for deferred transaction") while 'deferrable'
flag can be uninitialized for non-control/notify AV/C transactions.
UBSAN reports it:

This commit fixes the bug. The bug has no disadvantage for the non-
control/notify AV/C transactions since the flag has an effect for AV/C
response with INTERIM (0x0f) status which is not used for the transactions
in AV/C general specification.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tty: synclink_gt: Fix null-pointer-dereference in slgt_clean()
When the driver fails at alloc_hdlcdev(), and then we remove the driver
module, we will get the following splat:
[ 25.065966] general protection fault, probably for non-canonical address 0xdffffc0000000182: 0000 [#1] PREEMPT SMP KASAN PTI
[ 25.066914] KASAN: null-ptr-deref in range [0x0000000000000c10-0x0000000000000c17]
[ 25.069262] RIP: 0010:detach_hdlc_protocol+0x2a/0x3e0
[ 25.077709] Call Trace:

[ 25.078481] slgt_cleanup+0x157/0x9f0 [synclink_gt]
Fix this by checking whether the 'info->netdev' is a null pointer first.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, arm64: Clear prog->jited_len along prog->jited
syzbot reported an illegal copy_to_user() attempt
from bpf_prog_get_info_by_fd() [1]
There was no repro yet on this bug, but I think
that commit 0aef499f3172 ("mm/usercopy: Detect vmalloc overruns")
is exposing a prior bug in bpf arm64.
bpf_prog_get_info_by_fd() looks at prog->jited_len
to determine if the JIT image can be copied out to user space.
My theory is that syzbot managed to get a prog where prog->jited_len
has been set to 43, while prog->bpf_func has ben cleared.
It is not clear why copy_to_user(uinsns, NULL, ulen) is triggering
this particular warning.
I thought find_vma_area(NULL) would not find a vm_struct.
As we do not hold vmap_area_lock spinlock, it might be possible
that the found vm_struct was garbage.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: potential buffer overflow in handling symlinks
Smatch printed a warning:
arch/x86/crypto/poly1305_glue.c:198 poly1305_update_arch() error:
__memcpy() 'dctx->buf' too small (16 vs u32max)
It's caused because Smatch marks 'link_len' as untrusted since it comes
from sscanf(). Add a check to ensure that 'link_len' is not larger than
the size of the 'link_str' buffer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: bcm2835: bcm2835_spi_handle_err(): fix NULL pointer deref for non DMA transfers
In case a IRQ based transfer times out the bcm2835_spi_handle_err()
function is called. Since commit 1513ceee70f2 ("spi: bcm2835: Drop
dma_pending flag") the TX and RX DMA transfers are unconditionally
canceled, leading to NULL pointer derefs if ctlr->dma_tx or
ctlr->dma_rx are not set.
Fix the NULL pointer deref by checking that ctlr->dma_tx and
ctlr->dma_rx are valid pointers before accessing them.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: mv88e6xxx: Fix refcount leak in mv88e6xxx_mdios_register
of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
mv88e6xxx_mdio_register() pass the device node to of_mdiobus_register().
We don't need the device node after it.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: bcmgenet: Use stronger register read/writes to assure ordering
GCC12 appears to be much smarter about its dependency tracking and is
aware that the relaxed variants are just normal loads and stores and
this is causing problems like:

The assumption when these were relaxed seems to be that device memory
would be mapped non reordering, and that other constructs
(spinlocks/etc) would provide the barriers to assure that packet data
and in memory rings/queues were ordered with respect to device
register reads/writes. This itself seems a bit sketchy, but the real
problem with GCC12 is that it is moving the actual reads/writes around
at will as though they were independent operations when in truth they
are not, but the compiler can't know that. When looking at the
assembly dumps for many of these routines its possible to see very
clean, but not strictly in program order operations occurring as the
compiler would be free to do if these weren't actually register
reads/write operations.
Its possible to suppress the timeout with a liberal bit of dma_mb()'s
sprinkled around but the device still seems unable to reliably
send/receive data. A better plan is to use the safer readl/writel
everywhere.
Since this partially reverts an older commit, which notes the use of
the relaxed variants for performance reasons. I would suggest that
any performance problems

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/pm: fix the null pointer while the smu is disabled
It needs to check if the pp_funcs is initialized while release the
context, otherwise it will trigger null pointer panic while the software
smu is not enabled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
soc: bcm: Check for NULL return of devm_kzalloc()
As the potential failure of allocation, devm_kzalloc() may return NULL. Then
the 'pd->pmb' and the follow lines of code may bring null pointer dereference.
Therefore, it is better to check the return value of devm_kzalloc() to avoid
this confusion.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qedf: Ensure the copied buf is NUL terminated
Currently, we allocate a count-sized kernel buffer and copy count from
userspace to that buffer. Later, we use kstrtouint on this buffer but we
don't ensure that the string is terminated inside the buffer, this can
lead to OOB read when using kstrtouint. Fix this issue by using
memdup_user_nul instead of memdup_user.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/bridge: anx7625: Fix overflow issue on reading EDID
The length of EDID block can be longer than 256 bytes, so we should use
`int` instead of `u8` for the `edid_pos` variable.

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: 8250: Fix PM usage_count for console handover
When console is enabled, univ8250_console_setup() calls
serial8250_console_setup() before .dev is set to uart_port. Therefore,
it will not call pm_runtime_get_sync(). Later, when the actual driver
is going to take over univ8250_console_exit() is called. As .dev is
already set, serial8250_console_exit() makes pm_runtime_put_sync() call
with usage count being zero triggering PM usage count warning
(extra debug for univ8250_console_setup(), univ8250_console_exit(), and
serial8250_register_ports()):
[ 0.068987] univ8250_console_setup ttyS0 nodev
[ 0.499670] printk: console [ttyS0] enabled
[ 0.717955] printk: console [ttyS0] printing thread started
[ 1.960163] serial8250_register_ports assigned dev for ttyS0
[ 1.976830] printk: console [ttyS0] disabled
[ 1.976888] printk: console [ttyS0] printing thread stopped
[ 1.977073] univ8250_console_exit ttyS0 usage:0
[ 1.977075] serial8250 serial8250: Runtime PM usage count underflow!
[ 1.977429] dw-apb-uart.6: ttyS0 at MMIO 0x4010006000 (irq = 33, base_baud = 115200) is a 16550A
[ 1.977812] univ8250_console_setup ttyS0 usage:2
[ 1.978167] printk: console [ttyS0] printing thread started
[ 1.978203] printk: console [ttyS0] enabled
To fix the issue, call pm_runtime_get_sync() in
serial8250_register_ports() as soon as .dev is set for an uart_port
if it has console enabled.
This problem became apparent only recently because 82586a721595 ("PM:
runtime: Avoid device usage count underflows") added the warning
printout. I confirmed this problem also occurs with v5.18 (w/o the
warning printout, obviously).

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: rt711-sdca: fix kernel NULL pointer dereference when IO error
The initial settings will be written before the codec probe function.
But, the rt711->component doesn't be assigned yet.
If IO error happened during initial settings operations, it will cause the kernel panic.
This patch changed component->dev to slave->dev to fix this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tunnels: do not assume mac header is set in skb_tunnel_check_pmtu()
Recently added debug in commit f9aefd6b2aa3 ("net: warn if mac header
was not set") caught a bug in skb_tunnel_check_pmtu(), as shown
in this syzbot report [1].
In ndo_start_xmit() paths, there is really no need to use skb->mac_header,
because skb->data is supposed to point at it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sysctl: Fix data races in proc_douintvec_minmax().
A sysctl variable is accessed concurrently, and there is always a chance
of data-race. So, all readers and writers need some basic protection to
avoid load/store-tearing.
This patch changes proc_douintvec_minmax() to use READ_ONCE() and
WRITE_ONCE() internally to fix data-races on the sysctl side. For now,
proc_douintvec_minmax() itself is tolerant to a data-race, but we still
need to add annotations on the other subsystem's side.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: libfc: Fix use after free in fc_exch_abts_resp()
fc_exch_release(ep) will decrease the ep's reference count. When the
reference count reaches zero, it is freed. But ep is still used in the
following code, which will lead to a use after free.
Return after the fc_exch_release() call to avoid use after free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: memcg: fix NULL pointer in mem_cgroup_track_foreign_dirty_slowpath()
As commit 18365225f044 ("hwpoison, memcg: forcibly uncharge LRU pages"),
hwpoison will forcibly uncharg a LRU hwpoisoned page, the folio_memcg
could be NULl, then, mem_cgroup_track_foreign_dirty_slowpath() could
occurs a NULL pointer dereference, let's do not record the foreign
writebacks for folio memcg is null in mem_cgroup_track_foreign_dirty() to
fix it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
igmp: Fix data-races around sysctl_igmp_qrv.
While reading sysctl_igmp_qrv, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its readers.
This test can be packed into a helper, so such changes will be in the
follow-up series after net is merged into net-next.
qrv ?: READ_ONCE(net->ipv4.sysctl_igmp_qrv);

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix crash when mount with quota enabled
There is a reported crash when mounting ocfs2 with quota enabled.
RIP: 0010:ocfs2_qinfo_lock_res_init+0x44/0x50 [ocfs2]
Call Trace:
ocfs2_local_read_info+0xb9/0x6f0 [ocfs2]
dquot_load_quota_sb+0x216/0x470
dquot_load_quota_inode+0x85/0x100
ocfs2_enable_quotas+0xa0/0x1c0 [ocfs2]
ocfs2_fill_super.cold+0xc8/0x1bf [ocfs2]

vfs_get_tree+0x25/0xb0
path_mount+0x465/0xac0
__x64_sys_mount+0x103/0x140
It is caused by when initializing dqi_gqlock, the corresponding dqi_type
and dqi_sb are not properly initialized.
This issue is introduced by commit 6c85c2c72819, which wants to avoid
accessing uninitialized variables in error cases. So make global quota
info properly initialized.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/reset: Fix error_state_read ptr + offset use
Fix our pointer offset usage in error_state_read
when there is no i915_gpu_coredump but buf offset
is non-zero.
This fixes a kernel page fault can happen when
multiple tests are running concurrently in a loop
and one is producing engine resets and consuming
the i915 error_state dump while the other is
forcing full GT resets. (takes a while to trigger).
The dmesg call trace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Fix a data-race in unix_dgram_peer_wake_me().
unix_dgram_poll() calls unix_dgram_peer_wake_me() without `other`'s
lock held and check if its receive queue is full. Here we need to
use unix_recvq_full_lockless() instead of unix_recvq_full(), otherwise
KCSAN will report a data-race.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ata: sata_dwc_460ex: Fix crash due to OOB write
the driver uses libata's "tag" values from in various arrays.
Since the mentioned patch bumped the ATA_TAG_INTERNAL to 32,
the value of the SATA_DWC_QCMD_MAX needs to account for that.
Otherwise ATA_TAG_INTERNAL usage cause similar crashes like
this as reported by Tice Rex on the OpenWrt Forum and
reproduced (with symbols) here:
| BUG: Kernel NULL pointer dereference at 0x00000000

| [cfa59bc8] [c03d324c] ata_identify_page_supported+0x68/0x130
| [...]
This is because sata_dwc_dma_xfer_complete() NULLs the
dma_pending's next neighbour "chan" (a *dma_chan struct) in
this '32' case right here (line ~735):
> hsdevp->dma_pending[tag] = SATA_DWC_DMA_PENDING_NONE;
Then the next time, a dma gets issued; dma_dwc_xfer_setup() passes
the NULL'd hsdevp->chan to the dmaengine_slave_config() which then
causes the crash.
With this patch, SATA_DWC_QCMD_MAX is now set to ATA_MAX_QUEUE + 1.
This avoids the OOB. But please note, there was a worthwhile discussion
on what ATA_TAG_INTERNAL and ATA_MAX_QUEUE is. And why there should not
be a "fake" 33 command-long queue size.
Ideally, the dw driver should account for the ATA_TAG_INTERNAL.
In Damien Le Moal's words: "... having looked at the driver, it
is a bigger change than just faking a 33rd "tag" that is in fact
not a command tag at all."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: mpt3sas: Fix use after free in _scsih_expander_node_remove()
The function mpt3sas_transport_port_remove() called in
_scsih_expander_node_remove() frees the port field of the sas_expander
structure, leading to the following use-after-free splat from KASAN when
the ioc_info() call following that function is executed (e.g. when doing
rmmod of the driver module):

Fix this by introducing the local variable port_id to store the port ID
value before executing mpt3sas_transport_port_remove(). This local variable
is then used in the call to ioc_info() instead of dereferencing the freed
port structure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xen/netback: avoid entering xenvif_rx_next_skb() with an empty rx queue
xenvif_rx_next_skb() is expecting the rx queue not being empty, but
in case the loop in xenvif_rx_action() is doing multiple iterations,
the availability of another skb in the rx queue is not being checked.
This can lead to crashes:

Summary
In the Linux kernel, the following vulnerability has been resolved:
xsk: Fix race at socket teardown
Fix a race in the xsk socket teardown code that can lead to a NULL pointer
dereference splat. The current xsk unbind code in xsk_unbind_dev() starts by
setting xs->state to XSK_UNBOUND, sets xs->dev to NULL and then waits for any
NAPI processing to terminate using synchronize_net(). After that, the release
code starts to tear down the socket state and free allocated memory.

There are two problems with the current code. First, setting xs->dev to NULL
before waiting for all users to stop using the socket is not correct. The
entry to the data plane functions xsk_poll(), xsk_sendmsg(), and xsk_recvmsg()
are all guarded by a test that xs->state is in the state XSK_BOUND and if not,
it returns right away. But one process might have passed this test but still
have not gotten to the point in which it uses xs->dev in the code. In this
interim, a second process executing xsk_unbind_dev() might have set xs->dev to
NULL which will lead to a crash for the first process. The solution here is
just to get rid of this NULL assignment since it is not used anymore. Before
commit 42fddcc7c64b ("xsk: use state member for socket synchronization"),
xs->dev was the gatekeeper to admit processes into the data plane functions,
but it was replaced with the state variable xs->state in the aforementioned
commit.
The second problem is that synchronize_net() does not wait for any process in
xsk_poll(), xsk_sendmsg(), or xsk_recvmsg() to complete, which means that the
state they rely on might be cleaned up prematurely. This can happen when the
notifier gets called (at driver unload for example) as it uses xsk_unbind_dev().
Solve this by extending the RCU critical region from just the ndo_xsk_wakeup
to the whole functions mentioned above, so that both the test of xs->state ==
XSK_BOUND and the last use of any member of xs is covered by the RCU critical
section. This will guarantee that when synchronize_net() completes, there will
be no processes left executing xsk_poll(), xsk_sendmsg(), or xsk_recvmsg() and
state can be cleaned up safely. Note that we need to drop the RCU lock for the
skb xmit path as it uses functions that might sleep. Due to this, we have to
retest the xs->state after we grab the mutex that protects the skb xmit code
from, among a number of things, an xsk_unbind_dev() being executed from the
notifier at the same time.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nxsk: Fix race at socket teardown\n\nFix a race in the xsk socket teardown code that can lead to a NULL pointer\ndereference splat. The current xsk unbind code in xsk_unbind_dev() starts by\nsetting xs-\u003estate to XSK_UNBOUND, sets xs-\u003edev to NULL and then waits for any\nNAPI processing to terminate using synchronize_net(). After that, the release\ncode starts to tear down the socket state and free allocated memory.\n\n BUG: kernel NULL pointer dereference, address: 00000000000000c0\n PGD 8000000932469067 P4D 8000000932469067 PUD 0\n Oops: 0000 [#1] PREEMPT SMP PTI\n CPU: 25 PID: 69132 Comm: grpcpp_sync_ser Tainted: G I 5.16.0+ #2\n Hardware name: Dell Inc.

First, setting xs-\u003edev to NULL\nbefore waiting for all users to stop using the socket is not correct. The\nentry to the data plane functions xsk_poll(), xsk_sendmsg(), and xsk_recvmsg()\nare all guarded by a test that xs-\u003estate is in the state XSK_BOUND and if not,\nit returns right away. But one process might have passed this test but still\nhave not gotten to the point in which it uses xs-\u003edev in the code. In this\ninterim, a second process executing xsk_unbind_dev() might have set xs-\u003edev to\nNULL which will lead to a crash for the first process. The solution here is\njust to get rid of this NULL assignment since it is not used anymore. Before\ncommit 42fddcc7c64b (\"xsk: use state member for socket synchronization\"),\nxs-\u003edev was the gatekeeper to admit processes into the data plane functions,\nbut it was replaced with the state variable xs-\u003estate in the aforementioned\ncommit.\n\nThe second problem is that synchronize_net() does not wait for any process in\nxsk_poll(), xsk_sendmsg(), or xsk_recvmsg() to complete, which means that the\nstate they rely on might be cleaned up prematurely. This can happen when the\nnotifier gets called (at driver unload for example) as it uses xsk_unbind_dev().\nSolve this by extending the RCU critical region from just the ndo_xsk_wakeup\nto the whole functions mentioned above, so that both the test of xs-\u003estate ==\nXSK_BOUND and the last use of any member of xs is covered by the RCU critical\nsection. This will guarantee that when synchronize_net() completes, there will\nbe no processes left executing xsk_poll(), xsk_sendmsg(), or xsk_recvmsg() and\nstate can be cleaned up safely. Note that we need to drop the RCU lock for the\nskb xmit path as it uses functions that might sleep. Due to this, we have to\nretest the xs-\u003estate after we grab the mutex that protects the skb xmit code\nfrom, among a number of things, an xsk_unbind_dev() being executed from the\nnotifier at the same time."

Summary
In the Linux kernel, the following vulnerability has been resolved:
gfs2: Always check inode size of inline inodes
Check if the inode size of stuffed (inline) inodes is within the allowed
range when reading inodes from disk (gfs2_dinode_in()). This prevents
us from on-disk corruption.
The two checks in stuffed_readpage() and gfs2_unstuffer_page() that just
truncate inline data to the maximum allowed size don't actually make
sense, and they can be removed now as well.

Summary
In the Linux kernel, the following vulnerability has been resolved:
octeontx2-pf: Fix the use of GFP_KERNEL in atomic context on rt
The commit 4af1b64f80fb ("octeontx2-pf: Fix lmtst ID used in aura
free") uses the get/put_cpu() to protect the usage of percpu pointer
in ->aura_freeptr() callback, but it also unnecessarily disable the
preemption for the blockable memory allocation. The commit 87b93b678e95
("octeontx2-pf: Avoid use of GFP_KERNEL in atomic context") tried to
fix these sleep inside atomic warnings. But it only fix the one for
the non-rt kernel. For the rt kernel, we still get the similar warnings
like below.
BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:46

Of course, we can shuffle the get/put_cpu() to only wrap the invocation
of ->aura_freeptr() as what commit 87b93b678e95 does. But there are only
two ->aura_freeptr() callbacks, otx2_aura_freeptr() and
cn10k_aura_freeptr(). There is no usage of perpcu variable in the
otx2_aura_freeptr() at all, so the get/put_cpu() seems redundant to it.
We can move the get/put_cpu() into the corresponding callback which
really has the percpu variable usage and avoid the sprinkling of
get/put_cpu() in several places.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: fix NULL pointer dereference in brcmf_txfinalize()
On removal of the device or unloading of the kernel module a potential NULL
pointer dereference occurs.
The following sequence deletes the interface:
brcmf_detach()
brcmf_remove_interface()
brcmf_del_if()
Inside the brcmf_del_if() function the drvr->if2bss[ifidx] is updated to
BRCMF_BSSIDX_INVALID (-1) if the bsscfgidx matches.
After brcmf_remove_interface() call the brcmf_proto_detach() function is
called providing the following sequence:
brcmf_detach()
brcmf_proto_detach()
brcmf_proto_msgbuf_detach()
brcmf_flowring_detach()
brcmf_msgbuf_delete_flowring()
brcmf_msgbuf_remove_flowring()
brcmf_flowring_delete()
brcmf_get_ifp()
brcmf_txfinalize()
Since brcmf_get_ip() can and actually will return NULL in this case the
call to brcmf_txfinalize() will result in a NULL pointer dereference inside
brcmf_txfinalize() when trying to update ifp->ndev->stats.tx_errors.
This will only happen if a flowring still has an skb.
Although the NULL pointer dereference has only been seen when trying to
update the tx statistic, all other uses of the ifp pointer have been
guarded as well with an early return if ifp is NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: imx-jpeg: Prevent decoding NV12M jpegs into single-planar buffers
If the application queues an NV12M jpeg as output buffer, but then
queues a single planar capture buffer, the kernel will crash with
"Unable to handle kernel NULL pointer dereference" in mxc_jpeg_addrs,
prevent this by finishing the job with error.

==
Figure out the race happens when one process is adding &page->lru into
the pagelist tail in fb_deferred_io_mkwrite(), another process is
re-initializing the same &page->lru in fb_deferred_io_fault(), which is
not protected by the lock.
This fix is to init all the page lists one time during initialization,
it not only fixes the list corruption, but also avoids INIT_LIST_HEAD()
redundantly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm: don't free the IRQ if it was not requested
As msm_drm_uninit() is called from the msm_drm_init() error path,
additional care should be necessary as not to call the free_irq() for
the IRQ that was not requested before (because an error occured earlier
than the request_irq() call).
This fixed the issue reported with the following backtrace:
[ 8.571329] Trying to free already-free IRQ 187

Summary
In the Linux kernel, the following vulnerability has been resolved:
watch_queue: Actually free the watch
free_watch() does everything barring actually freeing the watch object. Fix
this by adding the missing kfree.
kmemleak produces a report something like the following. Note that as an
address can be seen in the first word, the watch would appear to have gone
through call_rcu().
BUG: memory leak

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: pcm: Fix races among concurrent prealloc proc writes
We have no protection against concurrent PCM buffer preallocation
changes via proc files, and it may potentially lead to UAF or some
weird problem. This patch applies the PCM open_mutex to the proc
write operation for avoiding the racy proc writes and the PCM stream
open (and further operations).

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: fix 'scheduling while atomic' on aux critical err interrupt
There's a kernel BUG splat on processing aux critical error
interrupts in ice_misc_intr():
[ 2100.917085] BUG: scheduling while atomic: swapper/15/0/0x00010000

...
As Andrew correctly mentioned previously[0], the following call
ladder happens:
ice_misc_intr() <- hardirq
ice_send_event_to_aux()
device_lock()
mutex_lock()
might_sleep()
might_resched() <- oops
Add a new PF state bit which indicates that an aux critical error
occurred and serve it in ice_service_task() in process context.
The new ice_pf::oicr_err_reg is read-write in both hardirq and
process contexts, but only 3 bits of non-critical data probably
aren't worth explicit synchronizing (and they're even in the same
byte [31:24]).

Summary
In the Linux kernel, the following vulnerability has been resolved:
mt76: fix tx status related use-after-free race on station removal
There is a small race window where ongoing tx activity can lead to a skb
getting added to the status tracking idr after that idr has already been
cleaned up, which will keep the wcid linked in the status poll list.
Fix this by only adding status skbs if the wcid pointer is still assigned
in dev->wcid, which gets cleared early by mt76_sta_pre_rcu_remove

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/irdma: Prevent some integer underflows
My static checker complains that:
drivers/infiniband/hw/irdma/ctrl.c:3605 irdma_sc_ceq_init()
warn: can subtract underflow 'info->dev->hmc_fpm_misc.max_ceqs'?
It appears that "info->dev->hmc_fpm_misc.max_ceqs" comes from the firmware
in irdma_sc_parse_fpm_query_buf() so, yes, there is a chance that it could
be zero. Even if we trust the firmware, it's easy enough to change the
condition just as a hardenning measure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cpufreq: governor: Use kobject release() method to free dbs_data
The struct dbs_data embeds a struct gov_attr_set and
the struct gov_attr_set embeds a kobject. Since every kobject must have
a release() method and we can't use kfree() to free it directly,
so introduce cpufreq_dbs_data_release() to release the dbs_data via
the kobject::release() method. This fixes the calltrace like below:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ath11k: Fix frames flush failure caused by deadlock
We are seeing below warnings:
kernel: [25393.301506] ath11k_pci 0000:01:00.0: failed to flush mgmt transmit queue 0
kernel: [25398.421509] ath11k_pci 0000:01:00.0: failed to flush mgmt transmit queue 0
kernel: [25398.421831] ath11k_pci 0000:01:00.0: dropping mgmt frame for vdev 0, is_started 0
this means ath11k fails to flush mgmt. frames because wmi_mgmt_tx_work
has no chance to run in 5 seconds.
By setting /proc/sys/kernel/hung_task_timeout_secs to 20 and increasing
ATH11K_FLUSH_TIMEOUT to 50 we get below warnings:

Summary
In the Linux kernel, the following vulnerability has been resolved:
netpoll: Fix race condition in netpoll_owner_active
KCSAN detected a race condition in netpoll:
BUG: KCSAN: data-race in net_rx_action / netpoll_send_skb
write (marked) to 0xffff8881164168b0 of 4 bytes by interrupt on cpu 10:
net_rx_action (./include/linux/netpoll.h:90 net/core/dev.c:6712 net/core/dev.c:6822)
<snip>
read to 0xffff8881164168b0 of 4 bytes by task 1 on cpu 2:
netpoll_send_skb (net/core/netpoll.c:319 net/core/netpoll.c:345 net/core/netpoll.c:393)
netpoll_send_udp (net/core/netpoll.c:?)
<snip>
value changed: 0x0000000a -> 0xffffffff
This happens because netpoll_owner_active() needs to check if the
current CPU is the owner of the lock, touching napi->poll_owner
non atomically. The ->poll_owner field contains the current CPU holding
the lock.
Use an atomic read to check if the poll owner is the current CPU.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers: usb: host: Fix deadlock in oxu_bus_suspend()
There is a deadlock in oxu_bus_suspend(), which is shown below:
(Thread 1) | (Thread 2)
| timer_action()
oxu_bus_suspend() | mod_timer()
spin_lock_irq() //(1) | (wait a time)
... | oxu_watchdog()
del_timer_sync() | spin_lock_irq() //(2)
(wait timer to stop) | ...
We hold oxu->lock in position (1) of thread 1, and use
del_timer_sync() to wait timer to stop, but timer handler
also need oxu->lock in position (2) of thread 2. As a result,
oxu_bus_suspend() will block forever.
This patch extracts del_timer_sync() from the protection of
spin_lock_irq(), which could let timer handler to obtain
the needed lock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/dp: Fix OOB read when handling Post Cursor2 register
The link_status array was not large enough to read the Adjust Request
Post Cursor2 register, so remove the common helper function to avoid
an OOB read, found with a -Warray-bounds build:
drivers/gpu/drm/drm_dp_helper.c: In function 'drm_dp_get_adjust_request_post_cursor':
drivers/gpu/drm/drm_dp_helper.c:59:27: error: array subscript 10 is outside array bounds of 'const u8[6]' {aka 'const unsigned char[6]'} [-Werror=array-bounds]
59 | return link_status[r - DP_LANE0_1_STATUS];
| ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/drm_dp_helper.c:147:51: note: while referencing 'link_status'
147 | u8 drm_dp_get_adjust_request_post_cursor(const u8 link_status[DP_LINK_STATUS_SIZE],
| ~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Replace the only user of the helper with an open-coded fetch and decode,
similar to drivers/gpu/drm/amd/display/dc/core/dc_link_dp.c.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers: staging: rtl8723bs: Fix deadlock in rtw_surveydone_event_callback()
There is a deadlock in rtw_surveydone_event_callback(),
which is shown below:
(Thread 1) | (Thread 2)
| _set_timer()
rtw_surveydone_event_callback()| mod_timer()
spin_lock_bh() //(1) | (wait a time)
... | rtw_scan_timeout_handler()
del_timer_sync() | spin_lock_bh() //(2)
(wait timer to stop) | ...
We hold pmlmepriv->lock in position (1) of thread 1 and use
del_timer_sync() to wait timer to stop, but timer handler
also need pmlmepriv->lock in position (2) of thread 2.
As a result, rtw_surveydone_event_callback() will block forever.
This patch extracts del_timer_sync() from the protection of
spin_lock_bh(), which could let timer handler to obtain
the needed lock. What`s more, we change spin_lock_bh() in
rtw_scan_timeout_handler() to spin_lock_irq(). Otherwise,
spin_lock_bh() will also cause deadlock() in timer handler.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/plane: Move range check for format_count earlier
While the check for format_count > 64 in __drm_universal_plane_init()
shouldn't be hit (it's a WARN_ON), in its current position it will then
leak the plane->format_types array and fail to call
drm_mode_object_unregister() leaking the modeset identifier. Move it to
the start of the function to avoid allocating those resources in the
first place.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mtd: rawnand: atmel: fix refcount issue in atmel_nand_controller_init
The reference counting issue happens in several error handling paths
on a refcounted object "nc->dmac". In these paths, the function simply
returns the error code, forgetting to balance the reference count of
"nc->dmac", increased earlier by dma_request_channel(), which may
cause refcount leaks.
Fix it by decrementing the refcount of specific object in those error
paths.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: prevent bad output lengths in smb2_ioctl_query_info()
When calling smb2_ioctl_query_info() with
smb_query_info::flags=PASSTHRU_FSCTL and
smb_query_info::output_buffer_length=0, the following would return
0x10
buffer = memdup_user(arg + sizeof(struct smb_query_info),
qi.output_buffer_length);
if (IS_ERR(buffer)) {
kfree(vars);
return PTR_ERR(buffer);
}
rather than a valid pointer thus making IS_ERR() check fail. This
would then cause a NULL ptr deference in @buffer when accessing it
later in smb2_ioctl_query_ioctl(). While at it, prevent having a
@buffer smaller than 8 bytes to correctly handle SMB2_SET_INFO
FileEndOfFileInformation requests when
smb_query_info::flags=PASSTHRU_SET_INFO.
Here is a small C reproducer which triggers a NULL ptr in @buffer when
passing an invalid smb_query_info::flags
#include <stdio.h>

if (argc < 2)

fd = open(argv[1], O_RDONLY);
if (fd == -1)
die("open");
if (ioctl(fd, QUERY_INFO, (uint32_t[]) { 0, 0, 0, 4, 0, 0}) == -1)
die("ioctl");
close(fd);
return 0;

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: pvrusb2: fix array-index-out-of-bounds in pvr2_i2c_core_init
Syzbot reported that -1 is used as array index. The problem was in
missing validation check.
hdw->unit_number is initialized with -1 and then if init table walk fails
this value remains unchanged. Since code blindly uses this member for
array indexing adding sanity check is the easiest fix for that.
hdw->workpoll initialization moved upper to prevent warning in
__flush_work.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: accel: mma8452: use the correct logic to get mma8452_data
The original logic to get mma8452_data is wrong, the *dev point to
the device belong to iio_dev. we can't use this dev to find the
correct i2c_client. The original logic happen to work because it
finally use dev->driver_data to get iio_dev. Here use the API
to_i2c_client() is wrong and make reader confuse. To correct the
logic, it should be like this
struct mma8452_data *data = iio_priv(dev_get_drvdata(dev));
But after commit 8b7651f25962 ("iio: iio_device_alloc(): Remove
unnecessary self drvdata"), the upper logic also can't work.
When try to show the avialable scale in userspace, will meet kernel
dump, kernel handle NULL pointer dereference.
So use dev_to_iio_dev() to correct the logic.
Dual fixes tags as the second reflects when the bug was exposed, whilst
the first reflects when the original bug was introduced.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix pointer-leak due to insufficient speculative store bypass mitigation
To mitigate Spectre v4, 2039f26f3aca ("bpf: Fix leakage due to
insufficient speculative store bypass mitigation") inserts lfence
instructions after 1) initializing a stack slot and 2) spilling a
pointer to the stack.
However, this does not cover cases where a stack slot is first
initialized with a pointer (subject to sanitization) but then
overwritten with a scalar (not subject to sanitization because
the slot was already initialized). In this case, the second write
may be subject to speculative store bypass (SSB) creating a
speculative pointer-as-scalar type confusion. This allows the
program to subsequently leak the numerical pointer value using,
for example, a branch-based cache side channel.
To fix this, also sanitize scalars if they write a stack slot
that previously contained a pointer. Assuming that pointer-spills
are only generated by LLVM on register-pressure, the performance
impact on most real-world BPF programs should be small.
The following unprivileged BPF bytecode drafts a minimal exploit
and the mitigation:
[...]
// r6 = 0 or 1 (skalar, unknown user input)
// r7 = accessible ptr for side channel
// r10 = frame pointer (fp), to be leaked
//
r9 = r10 # fp alias to encourage ssb
*(u64 *)(r9 - 8) = r10 // fp[-8] = ptr, to be leaked
// lfence added here because of pointer spill to stack.
//
// Ommitted: Dummy bpf_ringbuf_output() here to train alias predictor
// for no r9-r10 dependency.
//
*(u64 *)(r10 - 8) = r6 // fp[-8] = scalar, overwrites ptr
// 2039f26f3aca: no lfence added because stack slot was not STACK_INVALID,
// store may be subject to SSB
//
// fix: also add an lfence when the slot contained a ptr
//
r8 = *(u64 *)(r9 - 8)
// r8 = architecturally a scalar, speculatively a ptr
//
// leak ptr using branch-based cache side channel:
r8 &= 1 // choose bit to leak
if r8 == 0 goto SLOW // no mispredict
// architecturally dead code if input r6 is 0,
// only executes speculatively iff ptr bit is 1
r8 = *(u64 *)(r7 + 0) # encode bit in cache (0: slow, 1: fast)
SLOW:
[...]
After running this, the program can time the access to *(r7 + 0) to
determine whether the chosen pointer bit was 0 or 1. Repeat this 64
times to recover the whole address on amd64.
In summary, sanitization can only be skipped if one scalar is
overwritten with another scalar. Scalar-confusion due to speculative
store bypass can not lead to invalid accesses because the pointer
bounds deducted during verification are enforced using branchless
logic. See 979d63d50c0c ("bpf: prevent out of bounds speculation on
pointer arithmetic") for details.
Do not make the mitigation depend on !env->allow_{uninit_stack,ptr_leaks}
because speculative leaks are likely unexpected if these were enabled.
For example, leaking the address to a protected log file may be acceptable
while disabling the mitigation might unintentionally leak the address
into the cached-state of a map that is accessible to unprivileged
processes.

In this case, the second write\nmay be subject to speculative store bypass (SSB) creating a\nspeculative pointer-as-scalar type confusion. This allows the\nprogram to subsequently leak the numerical pointer value using,\nfor example, a branch-based cache side channel.\n\nTo fix this, also sanitize scalars if they write a stack slot\nthat previously contained a pointer. Assuming that pointer-spills\nare only generated by LLVM on register-pressure, the performance\nimpact on most real-world BPF programs should be small.\n\nThe following unprivileged BPF bytecode drafts a minimal exploit\nand the mitigation:\n\n [...]\n // r6 = 0 or 1 (skalar, unknown user input)\n // r7 = accessible ptr for side channel\n // r10 = frame pointer (fp), to be leaked\n //\n r9 = r10 # fp alias to encourage ssb\n *(u64 *)(r9 - 8) = r10 // fp[-8] = ptr, to be leaked\n // lfence added here because of pointer spill to stack.\n //\n // Ommitted: Dummy bpf_ringbuf_output() here to train alias predictor\n // for no r9-r10 dependency.\n //\n *(u64 *)(r10 - 8) = r6 // fp[-8] = scalar, overwrites ptr\n // 2039f26f3aca: no lfence added because stack slot was not STACK_INVALID,\n // store may be subject to SSB\n //\n // fix: also add an lfence when the slot contained a ptr\n //\n r8 = *(u64 *)(r9 - 8)\n // r8 = architecturally a scalar, speculatively a ptr\n //\n // leak ptr using branch-based cache side channel:\n r8 \u0026= 1 // choose bit to leak\n if r8 == 0 goto SLOW // no mispredict\n // architecturally dead code if input r6 is 0,\n // only executes speculatively iff ptr bit is 1\n r8 = *(u64 *)(r7 + 0) # encode bit in cache (0: slow, 1: fast)\nSLOW:\n [...]\n\nAfter running this, the program can time the access to *(r7 + 0) to\ndetermine whether the chosen pointer bit was 0 or 1. Repeat this 64\ntimes to recover the whole address on amd64.\n\nIn summary, sanitization can only be skipped if one scalar is\noverwritten with another scalar. Scalar-confusion due to speculative\nstore bypass can not lead to invalid accesses because the pointer\nbounds deducted during verification are enforced using branchless\nlogic. See 979d63d50c0c (\"bpf: prevent out of bounds speculation on\npointer arithmetic\") for details.\n\nDo not make the mitigation depend on !env-\u003eallow_{uninit_stack,ptr_leaks}\nbecause speculative leaks are likely unexpected if these were enabled.\nFor example, leaking the address to a protected log file may be acceptable\nwhile disabling the mitigation might unintentionally leak the address\ninto the cached-state of a map that is accessible to unprivileged\nprocesses."

Summary
In the Linux kernel, the following vulnerability has been resolved:
netem: Update sch->q.qlen before qdisc_tree_reduce_backlog()
qdisc_tree_reduce_backlog() notifies parent qdisc only if child
qdisc becomes empty, therefore we need to reduce the backlog of the
child qdisc before calling it. Otherwise it would miss the opportunity
to call cops->qlen_notify(), in the case of DRR, it resulted in UAF
since DRR uses ->qlen_notify() to maintain its active list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: wc938x: fix accessing array out of bounds for enum type
Accessing enums using integer would result in array out of bounds access
on platforms like aarch64 where sizeof(long) is 8 compared to enum size
which is 4 bytes.
Fix this by using enumerated items instead of integers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fscache: Fix invalidation/lookup race
If an NFS file is opened for writing and closed, fscache_invalidate() will
be asked to invalidate the file - however, if the cookie is in the
LOOKING_UP state (or the CREATING state), then request to invalidate
doesn't get recorded for fscache_cookie_state_machine() to do something
with.
Fix this by making __fscache_invalidate() set a flag if it sees the cookie
is in the LOOKING_UP state to indicate that we need to go to invalidation.
Note that this requires a count on the n_accesses counter for the state
machine, which that will release when it's done.
fscache_cookie_state_machine() then shifts to the INVALIDATING state if it
sees the flag.
Without this, an nfs file can get corrupted if it gets modified locally and
then read locally as the cache contents may not get updated.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PM: core: keep irq flags in device_pm_check_callbacks()
The function device_pm_check_callbacks() can be called under the spin
lock (in the reported case it happens from genpd_add_device() ->
dev_pm_domain_set(), when the genpd uses spinlocks rather than mutexes.
However this function uncoditionally uses spin_lock_irq() /
spin_unlock_irq(), thus not preserving the CPU flags. Use the
irqsave/irqrestore instead.
The backtrace for the reference:

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - fix memory leak in RSA
When an RSA key represented in form 2 (as defined in PKCS #1 V2.1) is
used, some components of the private key persist even after the TFM is
released.
Replace the explicit calls to free the buffers in qat_rsa_exit_tfm()
with a call to qat_rsa_clear_ctx() which frees all buffers referenced in
the TFM context.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: Avoid putting some root ports into D3 on TUXEDO Sirius Gen1
commit 9d26d3a8f1b0 ("PCI: Put PCIe ports into D3 during suspend") sets the
policy that all PCIe ports are allowed to use D3. When the system is
suspended if the port is not power manageable by the platform and won't be
used for wakeup via a PME this sets up the policy for these ports to go
into D3hot.
This policy generally makes sense from an OSPM perspective but it leads to
problems with wakeup from suspend on the TUXEDO Sirius 16 Gen 1 with a
specific old BIOS. This manifests as a system hang.
On the affected Device + BIOS combination, add a quirk for the root port of
the problematic controller to ensure that these root ports are not put into
D3hot at suspend.
This patch is based on
https://lore.kernel.org/linux-pci/20230708214457.1229-2-mario.limonciello@amd.com
but with the added condition both in the documentation and in the code to
apply only to the TUXEDO Sirius 16 Gen 1 with a specific old BIOS and only
the affected root ports.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Fix double uncharge the mem of sk_msg
If tcp_bpf_sendmsg is running during a tear down operation, psock may be
freed.
tcp_bpf_sendmsg()
tcp_bpf_send_verdict()
sk_msg_return()
tcp_bpf_sendmsg_redir()
unlikely(!psock))
sk_msg_free()
The mem of msg has been uncharged in tcp_bpf_send_verdict() by
sk_msg_return(), and would be uncharged by sk_msg_free() again. When psock
is null, we can simply returning an error code, this would then trigger
the sk_msg_free_nocharge in the error path of __SK_REDIRECT and would have
the side effect of throwing an error up to user space. This would be a
slight change in behavior from user side but would look the same as an
error if the redirect on the socket threw an error.
This issue can cause the following info:
WARNING: CPU: 0 PID: 2136 at net/ipv4/af_inet.c:155 inet_sock_destruct+0x13c/0x260

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: check iparea_offset and ipv6_prefixes_cnt when receiving proposal msg
When receiving proposal msg in server, the field iparea_offset
and the field ipv6_prefixes_cnt in proposal msg are from the
remote client and can not be fully trusted. Especially the
field iparea_offset, once exceed the max value, there has the
chance to access wrong address, and crash may happen.
This patch checks iparea_offset and ipv6_prefixes_cnt before using them.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_qca: Use del_timer_sync() before freeing
While looking at a crash report on a timer list being corrupted, which
usually happens when a timer is freed while still active. This is
commonly triggered by code calling del_timer() instead of
del_timer_sync() just before freeing.
One possible culprit is the hci_qca driver, which does exactly that.
Eric mentioned that wake_retrans_timer could be rearmed via the work
queue, so also move the destruction of the work queue before
del_timer_sync().

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-throttle: Set BIO_THROTTLED when bio has been throttled
1.In current process, all bio will set the BIO_THROTTLED flag
after __blk_throtl_bio().
2.If bio needs to be throttled, it will start the timer and
stop submit bio directly. Bio will submit in
blk_throtl_dispatch_work_fn() when the timer expires.But in
the current process, if bio is throttled. The BIO_THROTTLED
will be set to bio after timer start. If the bio has been
completed, it may cause use-after-free blow.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/arm-smmu: fix possible null-ptr-deref in arm_smmu_device_probe()
It will cause null-ptr-deref when using 'res', if platform_get_resource()
returns NULL, so move using 'res' after devm_ioremap_resource() that
will check it to avoid null-ptr-deref.
And use devm_platform_get_and_ioremap_resource() to simplify code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i2c: piix4: Fix a memory leak in the EFCH MMIO support
The recently added support for EFCH MMIO regions introduced a memory
leak in that code path. The leak is caused by the fact that
release_resource() merely removes the resource from the tree but does
not free its memory. We need to call release_mem_region() instead,
which does free the memory. As a nice side effect, this brings back
some symmetry between the legacy and MMIO paths.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sock: redo the psock vs ULP protection check
Commit 8a59f9d1e3d4 ("sock: Introduce sk->sk_prot->psock_update_sk_prot()")
has moved the inet_csk_has_ulp(sk) check from sk_psock_init() to
the new tcp_bpf_update_proto() function. I'm guessing that this
was done to allow creating psocks for non-inet sockets.
Unfortunately the destruction path for psock includes the ULP
unwind, so we need to fail the sk_psock_init() itself.
Otherwise if ULP is already present we'll notice that later,
and call tcp_update_ulp() with the sk_proto of the ULP
itself, which will most likely result in the ULP looping
its callbacks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915: Fix potential bit_17 double-free
A userspace with multiple threads racing I915_GEM_SET_TILING to set the
tiling to I915_TILING_NONE could trigger a double free of the bit_17
bitmask. (Or conversely leak memory on the transition to tiled.) Move
allocation/free'ing of the bitmask within the section protected by the
obj lock.
[tursulin: Correct fixes tag and added cc stable.]
(cherry picked from commit 10e0cbaaf1104f449d695c80bcacf930dcd3c42e)

Summary
In the Linux kernel, the following vulnerability has been resolved:
arch/arm64: Fix topology initialization for core scheduling
Arm64 systems rely on store_cpu_topology() to call update_siblings_masks()
to transfer the toplogy to the various cpu masks. This needs to be done
before the call to notify_cpu_starting() which tells the scheduler about
each cpu found, otherwise the core scheduling data structures are setup
in a way that does not match the actual topology.
With smt_mask not setup correctly we bail on `cpumask_weight(smt_mask) == 1`
for !leaders in:
notify_cpu_starting()
cpuhp_invoke_callback_range()
sched_cpu_starting()
sched_core_cpu_starting()
which leads to rq->core not being correctly set for !leader-rq's.
Without this change stress-ng (which enables core scheduling in its prctl
tests in newer versions -- i.e. with PR_SCHED_CORE support) causes a warning
and then a crash (trimmed for legibility):

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: altera: Fix refcount leak in altera_tse_mdio_create
Every iteration of for_each_child_of_node() decrements
the reference count of the previous node.
When break from a for_each_child_of_node() loop,
we need to explicitly call of_node_put() on the child node when
not need anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: pcm: Fix potential AB/BA lock with buffer_mutex and mmap_lock
syzbot caught a potential deadlock between the PCM
runtime->buffer_mutex and the mm->mmap_lock. It was brought by the
recent fix to cover the racy read/write and other ioctls, and in that
commit, I overlooked a (hopefully only) corner case that may take the
revert lock, namely, the OSS mmap. The OSS mmap operation
exceptionally allows to re-configure the parameters inside the OSS
mmap syscall, where mm->mmap_mutex is already held. Meanwhile, the
copy_from/to_user calls at read/write operations also take the
mm->mmap_lock internally, hence it may lead to a AB/BA deadlock.
A similar problem was already seen in the past and we fixed it with a
refcount (in commit b248371628aa). The former fix covered only the
call paths with OSS read/write and OSS ioctls, while we need to cover
the concurrent access via both ALSA and OSS APIs now.
This patch addresses the problem above by replacing the buffer_mutex
lock in the read/write operations with a refcount similar as we've
used for OSS. The new field, runtime->buffer_accessing, keeps the
number of concurrent read/write operations. Unlike the former
buffer_mutex protection, this protects only around the
copy_from/to_user() calls; the other codes are basically protected by
the PCM stream lock. The refcount can be a negative, meaning blocked
by the ioctls. If a negative value is seen, the read/write aborts
with -EBUSY. In the ioctl side, OTOH, they check this refcount, too,
and set to a negative value for blocking unless it's already being
accessed.

It was brought by the\nrecent fix to cover the racy read/write and other ioctls, and in that\ncommit, I overlooked a (hopefully only) corner case that may take the\nrevert lock, namely, the OSS mmap. The OSS mmap operation\nexceptionally allows to re-configure the parameters inside the OSS\nmmap syscall, where mm-\u003emmap_mutex is already held. Meanwhile, the\ncopy_from/to_user calls at read/write operations also take the\nmm-\u003emmap_lock internally, hence it may lead to a AB/BA deadlock.\n\nA similar problem was already seen in the past and we fixed it with a\nrefcount (in commit b248371628aa). The former fix covered only the\ncall paths with OSS read/write and OSS ioctls, while we need to cover\nthe concurrent access via both ALSA and OSS APIs now.\n\nThis patch addresses the problem above by replacing the buffer_mutex\nlock in the read/write operations with a refcount similar as we\u0027ve\nused for OSS. The new field, runtime-\u003ebuffer_accessing, keeps the\nnumber of concurrent read/write operations. Unlike the former\nbuffer_mutex protection, this protects only around the\ncopy_from/to_user() calls; the other codes are basically protected by\nthe PCM stream lock. The refcount can be a negative, meaning blocked\nby the ioctls. If a negative value is seen, the read/write aborts\nwith -EBUSY. In the ioctl side, OTOH, they check this refcount, too,\nand set to a negative value for blocking unless it\u0027s already being\naccessed."

Summary
In the Linux kernel, the following vulnerability has been resolved:
remoteproc: qcom_q6v5_mss: Fix some leaks in q6v5_alloc_memory_region
The device_node pointer is returned by of_parse_phandle() or
of_get_child_by_name() with refcount incremented.
We should use of_node_put() on it when done.
This function only call of_node_put(node) when of_address_to_resource
succeeds, missing error cases.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/selftests: fix subtraction overflow bug
On some machines hole_end can be small enough to cause subtraction
overflow. On the other side (addr + 2 * min_alignment) can overflow
in case of mock tests. This patch should handle both cases.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tee: optee: Fix supplicant wait loop
OP-TEE supplicant is a user-space daemon and it's possible for it
be hung or crashed or killed in the middle of processing an OP-TEE
RPC call. It becomes more complicated when there is incorrect shutdown
ordering of the supplicant process vs the OP-TEE client application which
can eventually lead to system hang-up waiting for the closure of the
client application.
Allow the client process waiting in kernel for supplicant response to
be killed rather than indefinitely waiting in an unkillable state. Also,
a normal uninterruptible wait should not have resulted in the hung-task
watchdog getting triggered, but the endless loop would.
This fixes issues observed during system reboot/shutdown when supplicant

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/amdgpu/amdgpu_cs: fix refcount leak of a dma_fence obj
This issue takes place in an error path in
amdgpu_cs_fence_to_handle_ioctl(). When `info->in.what` falls into
default case, the function simply returns -EINVAL, forgetting to
decrement the reference count of a dma_fence obj, which is bumped
earlier by amdgpu_cs_get_fence(). This may result in reference count
leaks.
Fix it by decreasing the refcount of specific object before returning
the error code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ath5k: fix OOB in ath5k_eeprom_read_pcal_info_5111
The bug was found during fuzzing. Stacktrace locates it in
ath5k_eeprom_convert_pcal_info_5111.
When none of the curve is selected in the loop, idx can go
up to AR5K_EEPROM_N_PD_CURVES. The line makes pd out of bound.
pd = &chinfo[pier].pd_curves[idx];
There are many OOB writes using pd later in the code. So I
added a sanity check for idx. Checks for other loops involving
AR5K_EEPROM_N_PD_CURVES are not needed as the loop index is not
used outside the loops.
The patch is NOT tested with real device.
The following is the fuzzing report
BUG: KASAN: slab-out-of-bounds in ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k]

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: qcom: bam_dma: fix runtime PM underflow
Commit dbad41e7bb5f ("dmaengine: qcom: bam_dma: check if the runtime pm enabled")
caused unbalanced pm_runtime_get/put() calls when the bam is
controlled remotely. This commit reverts it and just enables pm_runtime
in all cases, the clk_* functions already just nop when the clock is NULL.
Also clean up a bit by removing unnecessary bamclk null checks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xprtrdma: treat all calls not a bcall when bc_serv is NULL
When a rdma server returns a fault format reply, nfs v3 client may
treats it as a bcall when bc service is not exist.
The debug message at rpcrdma_bc_receive_call are,
[56579.837169] RPC: rpcrdma_bc_receive_call: callback XID
00000001, length=20

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: j1939: fix errant WARN_ON_ONCE in j1939_session_deactivate
The conclusion "j1939_session_deactivate() should be called with a
session ref-count of at least 2" is incorrect. In some concurrent
scenarios, j1939_session_deactivate can be called with the session
ref-count less than 2. But there is not any problem because it
will check the session active state before session putting in
j1939_session_deactivate_locked().
Here is the concurrent scenario of the problem reported by syzbot
and my reproduction log.

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-mq: don't touch ->tagset in blk_mq_get_sq_hctx
blk_mq_run_hw_queues() could be run when there isn't queued request and
after queue is cleaned up, at that time tagset is freed, because tagset
lifetime is covered by driver, and often freed after blk_cleanup_queue()
returns.
So don't touch ->tagset for figuring out current default hctx by the mapping
built in request queue, so use-after-free on tagset can be avoided. Meantime
this way should be fast than retrieving mapping from tagset.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: fix oops when unload drivers paralleling
When unload hclge driver, it tries to disable sriov first for each
ae_dev node from hnae3_ae_dev_list. If user unloads hns3 driver at
the time, because it removes all the ae_dev nodes, and it may cause
oops.
But we can't simply use hnae3_common_lock for this. Because in the
process flow of pci_disable_sriov(), it will trigger the remove flow
of VF, which will also take hnae3_common_lock.
To fixes it, introduce a new mutex to protect the unload process.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/etnaviv: check for reaped mapping in etnaviv_iommu_unmap_gem
When the mapping is already reaped the unmap must be a no-op, as we
would otherwise try to remove the mapping twice, corrupting the involved
data structures.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm integrity: fix memory corruption when tag_size is less than digest size
It is possible to set up dm-integrity in such a way that the
"tag_size" parameter is less than the actual digest size. In this
situation, a part of the digest beyond tag_size is ignored.
In this case, dm-integrity would write beyond the end of the
ic->recalc_tags array and corrupt memory. The corruption happened in
integrity_recalc->integrity_sector_checksum->crypto_shash_final.
Fix this corruption by increasing the tags array so that it has enough
padding at the end to accomodate the loop in integrity_recalc() being
able to write a full digest size for the last member of the tags
array.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: CT: Fix cleanup of CT before cleanup of TC ct rules
CT cleanup assumes that all tc rules were deleted first, and so
is free to delete the CT shared resources (e.g the dr_action
fwd_action which is shared for all tuples). But currently for
uplink, this is happens in reverse, causing the below trace.
CT cleanup is called from:
mlx5e_cleanup_rep_tx()->mlx5e_cleanup_uplink_rep_tx()->
mlx5e_rep_tc_cleanup()->mlx5e_tc_esw_cleanup()->
mlx5_tc_ct_clean()
Only afterwards, tc cleanup is called from:
mlx5e_cleanup_rep_tx()->mlx5e_tc_ht_cleanup()
which would have deleted all the tc ct rules, and so delete
all the offloaded tuples.
Fix this reversing the order of init and on cleanup, which
will result in tc cleanup then ct cleanup.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: Fix double increment of client_count in dma_chan_get()
The first time dma_chan_get() is called for a channel the channel
client_count is incorrectly incremented twice for public channels,
first in balance_ref_count(), and again prior to returning. This
results in an incorrect client count which will lead to the
channel resources not being freed when they should be. A simple
test of repeated module load and unload of async_tx on a Dell
Power Edge R7425 also shows this resulting in a kref underflow
warning.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: nfc: Fix use-after-free in local_cleanup()
Fix a use-after-free that occurs in kfree_skb() called from
local_cleanup(). This could happen when killing nfc daemon (e.g. neard)
after detaching an nfc device.
When detaching an nfc device, local_cleanup() called from
nfc_llcp_unregister_device() frees local->rx_pending and decreases
local->ref by kref_put() in nfc_llcp_local_put().
In the terminating process, nfc daemon releases all sockets and it leads
to decreasing local->ref. After the last release of local->ref,
local_cleanup() called from local_release() frees local->rx_pending
again, which leads to the bug.
Setting local->rx_pending to NULL in local_cleanup() could prevent
use-after-free when local_cleanup() is called twice.
Found by a modified version of syzkaller.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ila: serialize calls to nf_register_net_hooks()
syzbot found a race in ila_add_mapping() [1]
commit 031ae72825ce ("ila: call nf_unregister_net_hooks() sooner")
attempted to fix a similar issue.
Looking at the syzbot repro, we have concurrent ILA_CMD_ADD commands.
Add a mutex to make sure at most one thread is calling nf_register_net_hooks().

Summary
In the Linux kernel, the following vulnerability has been resolved:
bus: fsl-mc-bus: fix KASAN use-after-free in fsl_mc_bus_remove()
In fsl_mc_bus_remove(), mc->root_mc_bus_dev->mc_io is passed to
fsl_destroy_mc_io(). However, mc->root_mc_bus_dev is already freed in
fsl_mc_device_remove(). Then reference to mc->root_mc_bus_dev->mc_io
triggers KASAN use-after-free. To avoid the use-after-free, keep the
reference to mc->root_mc_bus_dev->mc_io in a local variable and pass to
fsl_destroy_mc_io().
This patch needs rework to apply to kernels older than v5.15.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dlm: fix plock invalid read
This patch fixes an invalid read showed by KASAN. A unlock will allocate a
"struct plock_op" and a followed send_op() will append it to a global
send_list data structure. In some cases a followed dev_read() moves it
to recv_list and dev_write() will cast it to "struct plock_xop" and access
fields which are only available in those structures. At this point an
invalid read happens by accessing those fields.
To fix this issue the "callback" field is moved to "struct plock_op" to
indicate that a cast to "plock_xop" is allowed and does the additional
"plock_xop" handling if set.
Example of the KASAN output which showed the invalid read:

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndlm: fix plock invalid read\n\nThis patch fixes an invalid read showed by KASAN. A unlock will allocate a\n\"struct plock_op\" and a followed send_op() will append it to a global\nsend_list data structure. In some cases a followed dev_read() moves it\nto recv_list and dev_write() will cast it to \"struct plock_xop\" and access\nfields which are only available in those structures. At this point an\ninvalid read happens by accessing those fields.\n\nTo fix this issue the \"callback\" field is moved to \"struct plock_op\" to\nindicate that a cast to \"plock_xop\" is allowed and does the additional\n\"plock_xop\" handling if set.\n\nExample of the KASAN output which showed the invalid read:\n\n[ 2064.296453] ==================================================================\n[ 2064.304852] BUG: KASAN: slab-out-of-bounds in dev_write+0x52b/0x5a0 [dlm]\n[ 2064.306491] Read of size 8 at addr ffff88800ef227d8 by task dlm_controld/7484\n[ 2064.308168]\n[ 2064.308575] CPU: 0 PID: 7484 Comm: dlm_controld Kdump: loaded Not tainted 5.14.0+ #9\n[ 2064.310292] Hardware name: Red Hat KVM, BIOS 0.5.1 01/01/2011\n[ 2064.311618] Call Trace:\n[ 2064.312218] dump_stack_lvl+0x56/0x7b\n[ 2064.313150] print_address_description.constprop.8+0x21/0x150\n[ 2064.314578] ? dev_write+0x52b/0x5a0 [dlm]\n[ 2064.315610] ? dev_write+0x52b/0x5a0 [dlm]\n[ 2064.316595] kasan_report.cold.14+0x7f/0x11b\n[ 2064.317674] ? dev_write+0x52b/0x5a0 [dlm]\n[ 2064.318687] dev_write+0x52b/0x5a0 [dlm]\n[ 2064.319629] ? dev_read+0x4a0/0x4a0 [dlm]\n[ 2064.320713] ? bpf_lsm_kernfs_init_security+0x10/0x10\n[ 2064.321926] vfs_write+0x17e/0x930\n[ 2064.322769] ? __fget_light+0x1aa/0x220\n[ 2064.323753] ksys_write+0xf1/0x1c0\n[ 2064.324548] ? __ia32_sys_read+0xb0/0xb0\n[ 2064.325464] do_syscall_64+0x3a/0x80\n[ 2064.326387] entry_SYSCALL_64_after_hwframe+0x44/0xae\n[ 2064.327606] RIP: 0033:0x7f807e4ba96f\n[ 2064.328470] Code: 89 54 24 18 48 89 74 24 10 89 7c 24 08 e8 39 87 f8 ff 48 8b 54 24 18 48 8b 74 24 10 41 89 c0 8b 7c 24 08 b8 01 00 00 00 0f 05 \u003c48\u003e 3d 00 f0 ff ff 77 31 44 89 c7 48 89 44 24 08 e8 7c 87 f8 ff 48\n[ 2064.332902] RSP: 002b:00007ffd50cfe6e0 EFLAGS: 00000293 ORIG_RAX: 0000000000000001\n[ 2064.334658] RAX: ffffffffffffffda RBX: 000055cc3886eb30 RCX: 00007f807e4ba96f\n[ 2064.336275] RDX: 0000000000000040 RSI: 00007ffd50cfe7e0 RDI: 0000000000000010\n[ 2064.337980] RBP: 00007ffd50cfe7e0 R08: 0000000000000000 R09: 0000000000000001\n[ 2064.339560] R10: 000055cc3886eb30 R11: 0000000000000293 R12: 000055cc3886eb80\n[ 2064.341237] R13: 000055cc3886eb00 R14: 000055cc3886f590 R15: 0000000000000001\n[ 2064.342857]\n[ 2064.343226] Allocated by task 12438:\n[ 2064.344057] kasan_save_stack+0x1c/0x40\n[ 2064.345079] __kasan_kmalloc+0x84/0xa0\n[ 2064.345933] kmem_cache_alloc_trace+0x13b/0x220\n[ 2064.346953] dlm_posix_unlock+0xec/0x720 [dlm]\n[ 2064.348811] do_lock_file_wait.part.32+0xca/0x1d0\n[ 2064.351070] fcntl_setlk+0x281/0xbc0\n[ 2064.352879] do_fcntl+0x5e4/0xfe0\n[ 2064.354657] __x64_sys_fcntl+0x11f/0x170\n[ 2064.356550] do_syscall_64+0x3a/0x80\n[ 2064.358259] entry_SYSCALL_64_after_hwframe+0x44/0xae\n[ 2064.360745]\n[ 2064.361511] Last potentially related work creation:\n[ 2064.363957] kasan_save_stack+0x1c/0x40\n[ 2064.365811] __kasan_record_aux_stack+0xaf/0xc0\n[ 2064.368100] call_rcu+0x11b/0xf70\n[ 2064.369785] dlm_process_incoming_buffer+0x47d/0xfd0 [dlm]\n[ 2064.372404] receive_from_sock+0x290/0x770 [dlm]\n[ 2064.374607] process_recv_sockets+0x32/0x40 [dlm]\n[ 2064.377290] process_one_work+0x9a8/0x16e0\n[ 2064.379357] worker_thread+0x87/0xbf0\n[ 2064.381188] kthread+0x3ac/0x490\n[ 2064.383460] ret_from_fork+0x22/0x30\n[ 2064.385588]\n[ 2064.386518] Second to last potentially related work creation:\n[ 2064.389219] kasan_save_stack+0x1c/0x40\n[ 2064.391043] __kasan_record_aux_stack+0xaf/0xc0\n[ 2064.393303] call_rcu+0x11b/0xf70\n[ 2064.394885] dlm_process_incoming_buffer+0x47d/0xfd0 [dlm]\n[ 2064.397694] receive_from_sock+0x290/0x770 \n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
ppp: Fix KMSAN uninit-value warning with bpf
Syzbot caught an "KMSAN: uninit-value" warning [1], which is caused by the
ppp driver not initializing a 2-byte header when using socket filter.
The following code can generate a PPP filter BPF program:
'''
struct bpf_program fp;
pcap_t *handle;
handle = pcap_open_dead(DLT_PPP_PPPD, 65535);
pcap_compile(handle, &fp, "ip and outbound", 0, 0);
bpf_dump(&fp, 1);
'''
Its output is:
'''
(000) ldh [2]
(001) jeq #0x21 jt 2 jf 5
(002) ldb [0]
(003) jeq #0x1 jt 4 jf 5
(004) ret #65535
(005) ret #0
'''
Wen can find similar code at the following link:
https://github.com/ppp-project/ppp/blob/master/pppd/options.c#L1680
The maintainer of this code repository is also the original maintainer
of the ppp driver.
As you can see the BPF program skips 2 bytes of data and then reads the
'Protocol' field to determine if it's an IP packet. Then it read the first
byte of the first 2 bytes to determine the direction.
The issue is that only the first byte indicating direction is initialized
in current ppp driver code while the second byte is not initialized.
For normal BPF programs generated by libpcap, uninitialized data won't be
used, so it's not a problem. However, for carefully crafted BPF programs,
such as those generated by syzkaller [2], which start reading from offset
0, the uninitialized data will be used and caught by KMSAN.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/set_memory: Avoid spinlock recursion in change_page_attr()
Commit 1f9ad21c3b38 ("powerpc/mm: Implement set_memory() routines")
included a spin_lock() to change_page_attr() in order to
safely perform the three step operations. But then
commit 9f7853d7609d ("powerpc/mm: Fix set_memory_*() against
concurrent accesses") modify it to use pte_update() and do
the operation safely against concurrent access.
In the meantime, Maxime reported some spinlock recursion.

Remove the read / modify / write sequence to make the operation atomic
and remove the spin_lock() in change_page_attr().
To do the operation atomically, we can't use pte modification helpers
anymore. Because all platforms have different combination of bits, it
is not easy to use those bits directly. But all have the
_PAGE_KERNEL_{RO/ROX/RW/RWX} set of flags. All we need it to compare
two sets to know which bits are set or cleared.
For instance, by comparing _PAGE_KERNEL_ROX and _PAGE_KERNEL_RO you
know which bit gets cleared and which bit get set when changing exec
permission.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ubifs: Fix deadlock in concurrent rename whiteout and inode writeback

, are caused by concurrent rename whiteout and inode writeback processes:
rename_whiteout(Thread 1) wb_workfn(Thread2)
ubifs_rename
do_rename
lock_4_inodes (Hold ui_mutex)
ubifs_budget_space
make_free_space
shrink_liability

bdi_split_work_to_wbs (Queue new wb work)
wb_do_writeback(wb work)
__writeback_single_inode
ubifs_write_inode
LOCK(ui_mutex)
↑
wb_wait_for_completion (Wait wb work) <-- deadlock!
Reproducer (Detail program in [Link]):
1. SYS_renameat2("/mp/dir/file", "/mp/dir/whiteout", RENAME_WHITEOUT)
2. Consume out of space before kernel(mdelay) doing budget for whiteout
Fix it by doing whiteout space budget before locking ubifs inodes.
BTW, it also fixes wrong goto tag 'out_release' in whiteout budget
error handling path(It should at least recover dir i_size and unlock
4 ubifs inodes).

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/hfi1: Fix use-after-free bug for mm struct
Under certain conditions, such as MPI_Abort, the hfi1 cleanup code may
represent the last reference held on the task mm.
hfi1_mmu_rb_unregister() then drops the last reference and the mm is freed
before the final use in hfi1_release_user_pages(). A new task may
allocate the mm structure while it is still being used, resulting in
problems. One manifestation is corruption of the mmap_sem counter leading
to a hang in down_write(). Another is corruption of an mm struct that is
in use by another task.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFC: NULL out the dev->rfkill to prevent UAF
Commit 3e3b5dfcd16a ("NFC: reorder the logic in nfc_{un,}register_device")
assumes the device_is_registered() in function nfc_dev_up() will help
to check when the rfkill is unregistered. However, this check only
take effect when device_del(&dev->dev) is done in nfc_unregister_device().
Hence, the rfkill object is still possible be dereferenced.
The crash trace in latest kernel (5.18-rc2):

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: add reserved GDT blocks check
We capture a NULL pointer issue when resizing a corrupt ext4 image which
is freshly clear resize_inode feature (not run e2fsck). It could be
simply reproduced by following steps. The problem is because of the
resize_inode feature was cleared, and it will convert the filesystem to
meta_bg mode in ext4_resize_fs(), but the es->s_reserved_gdt_blocks was
not reduced to zero, so could we mistakenly call reserve_backup_gdb()
and passing an uninitialized resize_inode to it when adding new group
descriptors.
mkfs.ext4 /dev/sda 3G
tune2fs -O ^resize_inode /dev/sda #forget to run requested e2fsck
mount /dev/sda /mnt
resize2fs /dev/sda 8G
========
BUG: kernel NULL pointer dereference, address: 0000000000000028
CPU: 19 PID: 3243 Comm: resize2fs Not tainted 5.18.0-rc7-00001-gfde086c5ebfd #748

RIP: 0033:0x7f2dd739617b
========
The fix is simple, add a check in ext4_resize_begin() to make sure that
the es->s_reserved_gdt_blocks is zero when the resize_inode feature is
disabled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netlink: terminate outstanding dump on socket close
Netlink supports iterative dumping of data. It provides the families
the following ops:
- start - (optional) kicks off the dumping process
- dump - actual dump helper, keeps getting called until it returns 0
- done - (optional) pairs with .start, can be used for cleanup
The whole process is asynchronous and the repeated calls to .dump
don't actually happen in a tight loop, but rather are triggered
in response to recvmsg() on the socket.
This gives the user full control over the dump, but also means that
the user can close the socket without getting to the end of the dump.
To make sure .start is always paired with .done we check if there
is an ongoing dump before freeing the socket, and if so call .done.
The complication is that sockets can get freed from BH and .done
is allowed to sleep. So we use a workqueue to defer the call, when
needed.
Unfortunately this does not work correctly. What we defer is not
the cleanup but rather releasing a reference on the socket.
We have no guarantee that we own the last reference, if someone
else holds the socket they may release it in BH and we're back
to square one.
The whole dance, however, appears to be unnecessary. Only the user
can interact with dumps, so we can clean up when socket is closed.
And close always happens in process context. Some async code may
still access the socket after close, queue notification skbs to it etc.
but no dumps can start, end or otherwise make progress.
Delete the workqueue and flush the dump state directly from the release
handler. Note that further cleanup is possible in -next, for instance
we now always call .done before releasing the main module reference,
so dump doesn't have to take a reference of its own.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix UAF due to race between btf_try_get_module and load_module
While working on code to populate kfunc BTF ID sets for module BTF from
its initcall, I noticed that by the time the initcall is invoked, the
module BTF can already be seen by userspace (and the BPF verifier). The
existing btf_try_get_module calls try_module_get which only fails if
mod->state == MODULE_STATE_GOING, i.e. it can increment module reference
when module initcall is happening in parallel.
Currently, BTF parsing happens from MODULE_STATE_COMING notifier
callback. At this point, the module initcalls have not been invoked.
The notifier callback parses and prepares the module BTF, allocates an
ID, which publishes it to userspace, and then adds it to the btf_modules
list allowing the kernel to invoke btf_try_get_module for the BTF.
However, at this point, the module has not been fully initialized (i.e.
its initcalls have not finished). The code in module.c can still fail
and free the module, without caring for other users. However, nothing
stops btf_try_get_module from succeeding between the state transition
from MODULE_STATE_COMING to MODULE_STATE_LIVE.
This leads to a use-after-free issue when BPF program loads
successfully in the state transition, load_module's do_init_module call
fails and frees the module, and BPF program fd on close calls module_put
for the freed module. Future patch has test case to verify we don't
regress in this area in future.
There are multiple points after prepare_coming_module (in load_module)
where failure can occur and module loading can return error. We
illustrate and test for the race using the last point where it can
practically occur (in module __init function).
An illustration of the race:
CPU 0 CPU 1
load_module
notifier_call(MODULE_STATE_COMING)
btf_parse_module
btf_alloc_id // Published to userspace
list_add(&btf_mod->list, btf_modules)
mod->init(...)
... ^
bpf_check |
check_pseudo_btf_id |
btf_try_get_module |
returns true | ...
... | module __init in progress
return prog_fd | ...
... V
if (ret < 0)
free_module(mod)
...
close(prog_fd)
...
bpf_prog_free_deferred
module_put(used_btf.mod) // use-after-free
We fix this issue by setting a flag BTF_MODULE_F_LIVE, from the notifier
callback when MODULE_STATE_LIVE state is reached for the module, so that
we return NULL from btf_try_get_module for modules that are not fully
formed. Since try_module_get already checks that module is not in
MODULE_STATE_GOING state, and that is the only transition a live module
can make before being removed from btf_modules list, this is enough to
close the race and prevent the bug.
A later selftest patch crafts the race condition artifically to verify
that it has been fixed, and that verifier fails to load program (with
ENXIO).
Lastly, a couple of comments:
1. Even if this race didn't exist, it seems more appropriate to only
access resources (ksyms and kfuncs) of a fully formed module which
has been initialized completely.
2. This patch was born out of need for synchronization against module
initcall for the next patch, so it is needed for correctness even
without the aforementioned race condition. The BTF resources
initialized by module initcall are set up once and then only looked
up, so just waiting until the initcall has finished ensures correct
behavior.

However, nothing\nstops btf_try_get_module from succeeding between the state transition\nfrom MODULE_STATE_COMING to MODULE_STATE_LIVE.\n\nThis leads to a use-after-free issue when BPF program loads\nsuccessfully in the state transition, load_module\u0027s do_init_module call\nfails and frees the module, and BPF program fd on close calls module_put\nfor the freed module. Future patch has test case to verify we don\u0027t\nregress in this area in future.\n\nThere are multiple points after prepare_coming_module (in load_module)\nwhere failure can occur and module loading can return error. We\nillustrate and test for the race using the last point where it can\npractically occur (in module __init function).\n\nAn illustration of the race:\n\nCPU 0 CPU 1\n\t\t\t load_module\n\t\t\t notifier_call(MODULE_STATE_COMING)\n\t\t\t btf_parse_module\n\t\t\t btf_alloc_id\t// Published to userspace\n\t\t\t list_add(\u0026btf_mod-\u003elist, btf_modules)\n\t\t\t mod-\u003einit(...)\n...\t\t\t\t^\nbpf_check\t\t |\ncheck_pseudo_btf_id |\n btf_try_get_module |\n returns true | ...\n... | module __init in progress\nreturn prog_fd | ...\n... V\n\t\t\t if (ret \u003c 0)\n\t\t\t free_module(mod)\n\t\t\t ...\nclose(prog_fd)\n ...\n bpf_prog_free_deferred\n module_put(used_btf.mod) // use-after-free\n\nWe fix this issue by setting a flag BTF_MODULE_F_LIVE, from the notifier\ncallback when MODULE_STATE_LIVE state is reached for the module, so that\nwe return NULL from btf_try_get_module for modules that are not fully\nformed. Since try_module_get already checks that module is not in\nMODULE_STATE_GOING state, and that is the only transition a live module\ncan make before being removed from btf_modules list, this is enough to\nclose the race and prevent the bug.\n\nA later selftest patch crafts the race condition artifically to verify\nthat it has been fixed, and that verifier fails to load program (with\nENXIO).\n\nLastly, a couple of comments:\n\n 1. Even if this race didn\u0027t exist, it seems more appropriate to only\n access resources (ksyms and kfuncs) of a fully formed module which\n has been initialized completely.\n\n 2. This patch was born out of need for synchronization against module\n initcall for the next patch, so it is needed for correctness even\n without the aforementioned race condition. The BTF resources\n initialized by module initcall are set up once and then only looked\n up, so just waiting until the initcall has finished ensures correct\n behavior."

Summary
In the Linux kernel, the following vulnerability has been resolved:
acct: perform last write from workqueue
In [1] it was reported that the acct(2) system call can be used to
trigger NULL deref in cases where it is set to write to a file that
triggers an internal lookup. This can e.g., happen when pointing acc(2)
to /sys/power/resume. At the point the where the write to this file
happens the calling task has already exited and called exit_fs(). A
lookup will thus trigger a NULL-deref when accessing current->fs.
Reorganize the code so that the the final write happens from the
workqueue but with the caller's credentials. This preserves the
(strange) permission model and has almost no regression risk.
This api should stop to exist though.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_fs: Prevent race during ffs_ep0_queue_wait
While performing fast composition switch, there is a possibility that the
process of ffs_ep0_write/ffs_ep0_read get into a race condition
due to ep0req being freed up from functionfs_unbind.
Consider the scenario that the ffs_ep0_write calls the ffs_ep0_queue_wait
by taking a lock &ffs->ev.waitq.lock. However, the functionfs_unbind isn't
bounded so it can go ahead and mark the ep0req to NULL, and since there
is no NULL check in ffs_ep0_queue_wait we will end up in use-after-free.
Fix this by making a serialized execution between the two functions using
a mutex_lock(ffs->mutex).

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: VMX: Prevent RSB underflow before vmenter
On VMX, there are some balanced returns between the time the guest's
SPEC_CTRL value is written, and the vmenter.
Balanced returns (matched by a preceding call) are usually ok, but it's
at least theoretically possible an NMI with a deep call stack could
empty the RSB before one of the returns.
For maximum paranoia, don't allow *any* returns (balanced or otherwise)
between the SPEC_CTRL write and the vmenter.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ath9k_htc: fix uninit value bugs
Syzbot reported 2 KMSAN bugs in ath9k. All of them are caused by missing
field initialization.
In htc_connect_service() svc_meta_len and pad are not initialized. Based
on code it looks like in current skb there is no service data, so simply
initialize svc_meta_len to 0.
htc_issue_send() does not initialize htc_frame_hdr::control array. Based
on firmware code, it will initialize it by itself, so simply zero whole
array to make KMSAN happy

lpfc_abort_handler routine so that it tries to take the lpfc_cmd->buf_lock
first before phba->hbalock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: add vlan list lock to protect vlan list
When adding port base VLAN, vf VLAN need to remove from HW and modify
the vlan state in vf VLAN list as false. If the periodicity task is
freeing the same node, it may cause "use after free" error.
This patch adds a vlan list lock to protect the vlan list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iavf: Fix handling of dummy receive descriptors
Fix memory leak caused by not handling dummy receive descriptor properly.
iavf_get_rx_buffer now sets the rx_buffer return value for dummy receive
descriptors. Without this patch, when the hardware writes a dummy
descriptor, iavf would not free the page allocated for the previous receive
buffer. This is an unlikely event but can still happen.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: gadget: Replace list_for_each_entry_safe() if using giveback
The list_for_each_entry_safe() macro saves the current item (n) and
the item after (n+1), so that n can be safely removed without
corrupting the list. However, when traversing the list and removing
items using gadget giveback, the DWC3 lock is briefly released,
allowing other routines to execute. There is a situation where, while
items are being removed from the cancelled_list using
dwc3_gadget_ep_cleanup_cancelled_requests(), the pullup disable
routine is running in parallel (due to UDC unbind). As the cleanup
routine removes n, and the pullup disable removes n+1, once the
cleanup retakes the DWC3 lock, it references a request who was already
removed/handled. With list debug enabled, this leads to a panic.
Ensure all instances of the macro are replaced where gadget giveback
is used.
Example call stack:
Thread#1:
__dwc3_gadget_ep_set_halt() - CLEAR HALT
-> dwc3_gadget_ep_cleanup_cancelled_requests()
->list_for_each_entry_safe()
->dwc3_gadget_giveback(n)
->dwc3_gadget_del_and_unmap_request()- n deleted[cancelled_list]
->spin_unlock
->Thread#2 executes
...
->dwc3_gadget_giveback(n+1)
->Already removed!
Thread#2:

->waiting for dwc3 spin_lock
...
->Thread#1 released lock
->dwc3_stop_active_transfers()
->dwc3_remove_requests()
->fetches n+1 item from cancelled_list (n removed by Thread#1)

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Inhibit aborts if external loopback plug is inserted
After running a short external loopback test, when the external loopback is
removed and a normal cable inserted that is directly connected to a target
device, the system oops in the llpfc_set_rrq_active() routine.
When the loopback was inserted an FLOGI was transmit. As we're looped back,
we receive the FLOGI request. The FLOGI is ABTS'd as we recognize the same
wppn thus understand it's a loopback. However, as the ABTS sends address
information the port is not set to (fffffe), the ABTS is dropped on the
wire. A short 1 frame loopback test is run and completes before the ABTS
times out. The looback is unplugged and the new cable plugged in, and the
an FLOGI to the new device occurs and completes. Due to a mixup in ref
counting the completion of the new FLOGI releases the fabric ndlp. Then the
original ABTS completes and references the released ndlp generating the
oops.
Correct by no-op'ing the ABTS when in loopback mode (it will be dropped
anyway). Added a flag to track the mode to recognize when it should be
no-op'd.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rapidio: fix an API misues when rio_add_net() fails
rio_add_net() calls device_register() and fails when device_register()
fails. Thus, put_device() should be used rather than kfree(). Add
"mport->net = NULL;" to avoid a use after free issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/papr_scm: Fix leaking nvdimm_events_map elements
Right now 'char *' elements allocated for individual 'stat_id' in
'papr_scm_priv.nvdimm_events_map[]' during papr_scm_pmu_check_events(), get
leaked in papr_scm_remove() and papr_scm_pmu_register(),
papr_scm_pmu_check_events() error paths.
Also individual 'stat_id' arent NULL terminated 'char *' instead they are fixed
8-byte sized identifiers. However papr_scm_pmu_register() assumes it to be a
NULL terminated 'char *' and at other places it assumes it to be a
'papr_scm_perf_stat.stat_id' sized string which is 8-byes in size.
Fix this by allocating the memory for papr_scm_priv.nvdimm_events_map to also
include space for 'stat_id' entries. This is possible since number of available
events/stat_ids are known upfront. This saves some memory and one extra level of
indirection from 'nvdimm_events_map' to 'stat_id'. Also rest of the code
can continue to call 'kfree(papr_scm_priv.nvdimm_events_map)' without needing to
iterate over the array and free up individual elements.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: lantiq_gswip: Fix refcount leak in gswip_gphy_fw_list
Every iteration of for_each_available_child_of_node() decrements
the reference count of the previous node.
when breaking early from a for_each_available_child_of_node() loop,
we need to explicitly call of_node_put() on the gphy_fw_np.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ubifs: Fix to add refcount once page is set private
MM defined the rule [1] very clearly that once page was set with PG_private
flag, we should increment the refcount in that page, also main flows like
pageout(), migrate_page() will assume there is one additional page
reference count if page_has_private() returns true. Otherwise, we may
get a BUG in page migration:
page:0000000080d05b9d refcount:-1 mapcount:0 mapping:000000005f4d82a8
index:0xe2 pfn:0x14c12
aops:ubifs_file_address_operations [ubifs] ino:8f1 dentry name:"f30e"
flags: 0x1fffff80002405(locked|uptodate|owner_priv_1|private|node=0|
zone=1|lastcpupid=0x1fffff)
page dumped because: VM_BUG_ON_PAGE(page_count(page) != 0)
------------[ cut here ]------------
kernel BUG at include/linux/page_ref.h:184!
invalid opcode: 0000 [#1] SMP
CPU: 3 PID: 38 Comm: kcompactd0 Not tainted 5.15.0-rc5
RIP: 0010:migrate_page_move_mapping+0xac3/0xe70
Call Trace:
ubifs_migrate_page+0x22/0xc0 [ubifs]

Before the time, we should make clean a concept, what does refcount means
in page gotten from grab_cache_page_write_begin(). There are 2 situations:
Situation 1: refcount is 3, page is created by __page_cache_alloc.
TYPE_A - the write process is using this page
TYPE_B - page is assigned to one certain mapping by calling
__add_to_page_cache_locked()
TYPE_C - page is added into pagevec list corresponding current cpu by
calling lru_cache_add()
Situation 2: refcount is 2, page is gotten from the mapping's tree
TYPE_B - page has been assigned to one certain mapping
TYPE_A - the write process is using this page (by calling
page_cache_get_speculative())
Filesystem releases one refcount by calling put_page() in xxx_write_end(),
the released refcount corresponds to TYPE_A (write task is using it). If
there are any processes using a page, page migration process will skip the
page by judging whether expected_page_refs() equals to page refcount.
The BUG is caused by following process:
PA(cpu 0) kcompactd(cpu 1)
compact_zone
ubifs_write_begin
page_a = grab_cache_page_write_begin
add_to_page_cache_lru
lru_cache_add
pagevec_add // put page into cpu 0's pagevec
(refcnf = 3, for page creation process)
ubifs_write_end
SetPagePrivate(page_a) // doesn't increase page count !
unlock_page(page_a)
put_page(page_a) // refcnt = 2
[...]
PB(cpu 0)
filemap_read
filemap_get_pages
add_to_page_cache_lru
lru_cache_add
__pagevec_lru_add // traverse all pages in cpu 0's pagevec
__pagevec_lru_add_fn
SetPageLRU(page_a)
isolate_migratepages
isolate_migratepages_block
get_page_unless_zero(page_a)
// refcnt = 3
list_add(page_a, from_list)
migrate_pages(from_list)
__unmap_and_move
move_to_new_page
ubifs_migrate_page(page_a)
migrate_page_move_mapping
expected_page_refs get 3
(migration[1] + mapping[1] + private[1])
release_pages
put_page_testzero(page_a) // refcnt = 3
page_ref_freeze // refcnt = 0
page_ref_dec_and_test(0 - 1 = -1)
page_ref_unfreeze
VM_BUG_ON_PAGE(-1 != 0, page)
UBIFS doesn't increase the page refcount after setting private flag, which
leads to page migration task believes the page is not used by any other
processes, so the page is migrated. This causes concurrent accessing on
page refcount between put_page() called by other process(eg. read process
calls lru_cache_add) and page_ref_unfreeze() called by mi

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: bonding: fix use-after-free after 802.3ad slave unbind
commit 0622cab0341c ("bonding: fix 802.3ad aggregator reselection"),
resolve case, when there is several aggregation groups in the same bond.
bond_3ad_unbind_slave will invalidate (clear) aggregator when
__agg_active_ports return zero. So, ad_clear_agg can be executed even, when
num_of_ports!=0. Than bond_3ad_unbind_slave can be executed again for,
previously cleared aggregator. NOTE: at this time bond_3ad_unbind_slave
will not update slave ports list, because lag_ports==NULL. So, here we
got slave ports, pointing to freed aggregator memory.
Fix with checking actual number of ports in group (as was before
commit 0622cab0341c ("bonding: fix 802.3ad aggregator reselection") ),
before ad_clear_agg().
The KASAN logs are as follows:

Summary
In the Linux kernel, the following vulnerability has been resolved:
phy: qcom-qmp: fix reset-controller leak on probe errors
Make sure to release the lane reset controller in case of a late probe
error (e.g. probe deferral).
Note that due to the reset controller being defined in devicetree in
"lane" child nodes, devm_reset_control_get_exclusive() cannot be used
directly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: properly terminate timers for kernel sockets
We had various syzbot reports about tcp timers firing after
the corresponding netns has been dismantled.
Fortunately Josef Bacik could trigger the issue more often,
and could test a patch I wrote two years ago.
When TCP sockets are closed, we call inet_csk_clear_xmit_timers()
to 'stop' the timers.
inet_csk_clear_xmit_timers() can be called from any context,
including when socket lock is held.
This is the reason it uses sk_stop_timer(), aka del_timer().
This means that ongoing timers might finish much later.
For user sockets, this is fine because each running timer
holds a reference on the socket, and the user socket holds
a reference on the netns.
For kernel sockets, we risk that the netns is freed before
timer can complete, because kernel sockets do not hold
reference on the netns.
This patch adds inet_csk_clear_xmit_timers_sync() function
that using sk_stop_timer_sync() to make sure all timers
are terminated before the kernel socket is released.
Modules using kernel sockets close them in their netns exit()
handler.
Also add sock_not_owned_by_me() helper to get LOCKDEP
support : inet_csk_clear_xmit_timers_sync() must not be called
while socket lock is held.
It is very possible we can revert in the future commit
3a58f13a881e ("net: rds: acquire refcount on TCP sockets")
which attempted to solve the issue in rds only.
(net/smc/af_smc.c and net/mptcp/subflow.c have similar code)
We probably can remove the check_net() tests from
tcp_out_of_resources() and __tcp_close() in the future.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915: fix a possible refcount leak in intel_dp_add_mst_connector()
If drm_connector_init fails, intel_connector_free will be called to take
care of proper free. So it is necessary to drop the refcount of port
before intel_connector_free.
(cherry picked from commit cea9ed611e85d36a05db52b6457bf584b7d969e2)

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: zswap: properly synchronize freeing resources during CPU hotunplug
In zswap_compress() and zswap_decompress(), the per-CPU acomp_ctx of the
current CPU at the beginning of the operation is retrieved and used
throughout. However, since neither preemption nor migration are disabled,
it is possible that the operation continues on a different CPU.
If the original CPU is hotunplugged while the acomp_ctx is still in use,
we run into a UAF bug as some of the resources attached to the acomp_ctx
are freed during hotunplug in zswap_cpu_comp_dead() (i.e.
acomp_ctx.buffer, acomp_ctx.req, or acomp_ctx.acomp).
The problem was introduced in commit 1ec3b5fe6eec ("mm/zswap: move to use
crypto_acomp API for hardware acceleration") when the switch to the
crypto_acomp API was made. Prior to that, the per-CPU crypto_comp was
retrieved using get_cpu_ptr() which disables preemption and makes sure the
CPU cannot go away from under us. Preemption cannot be disabled with the
crypto_acomp API as a sleepable context is needed.
Use the acomp_ctx.mutex to synchronize CPU hotplug callbacks allocating
and freeing resources with compression/decompression paths. Make sure
that acomp_ctx.req is NULL when the resources are freed. In the
compression/decompression paths, check if acomp_ctx.req is NULL after
acquiring the mutex (meaning the CPU was offlined) and retry on the new
CPU.
The initialization of acomp_ctx.mutex is moved from the CPU hotplug
callback to the pool initialization where it belongs (where the mutex is
allocated). In addition to adding clarity, this makes sure that CPU
hotplug cannot reinitialize a mutex that is already locked by
compression/decompression.
Previously a fix was attempted by holding cpus_read_lock() [1]. This
would have caused a potential deadlock as it is possible for code already
holding the lock to fall into reclaim and enter zswap (causing a
deadlock). A fix was also attempted using SRCU for synchronization, but
Johannes pointed out that synchronize_srcu() cannot be used in CPU hotplug
notifiers [2].
Alternative fixes that were considered/attempted and could have worked:
- Refcounting the per-CPU acomp_ctx. This involves complexity in
handling the race between the refcount dropping to zero in
zswap_[de]compress() and the refcount being re-initialized when the
CPU is onlined.
- Disabling migration before getting the per-CPU acomp_ctx [3], but
that's discouraged and is a much bigger hammer than needed, and could
result in subtle performance issues.

However, since neither preemption nor migration are disabled,\nit is possible that the operation continues on a different CPU.\n\nIf the original CPU is hotunplugged while the acomp_ctx is still in use,\nwe run into a UAF bug as some of the resources attached to the acomp_ctx\nare freed during hotunplug in zswap_cpu_comp_dead() (i.e. \nacomp_ctx.buffer, acomp_ctx.req, or acomp_ctx.acomp).\n\nThe problem was introduced in commit 1ec3b5fe6eec (\"mm/zswap: move to use\ncrypto_acomp API for hardware acceleration\") when the switch to the\ncrypto_acomp API was made. Prior to that, the per-CPU crypto_comp was\nretrieved using get_cpu_ptr() which disables preemption and makes sure the\nCPU cannot go away from under us. Preemption cannot be disabled with the\ncrypto_acomp API as a sleepable context is needed.\n\nUse the acomp_ctx.mutex to synchronize CPU hotplug callbacks allocating\nand freeing resources with compression/decompression paths. Make sure\nthat acomp_ctx.req is NULL when the resources are freed. In the\ncompression/decompression paths, check if acomp_ctx.req is NULL after\nacquiring the mutex (meaning the CPU was offlined) and retry on the new\nCPU.\n\nThe initialization of acomp_ctx.mutex is moved from the CPU hotplug\ncallback to the pool initialization where it belongs (where the mutex is\nallocated). In addition to adding clarity, this makes sure that CPU\nhotplug cannot reinitialize a mutex that is already locked by\ncompression/decompression.\n\nPreviously a fix was attempted by holding cpus_read_lock() [1]. This\nwould have caused a potential deadlock as it is possible for code already\nholding the lock to fall into reclaim and enter zswap (causing a\ndeadlock). A fix was also attempted using SRCU for synchronization, but\nJohannes pointed out that synchronize_srcu() cannot be used in CPU hotplug\nnotifiers [2].\n\nAlternative fixes that were considered/attempted and could have worked:\n- Refcounting the per-CPU acomp_ctx. This involves complexity in\n handling the race between the refcount dropping to zero in\n zswap_[de]compress() and the refcount being re-initialized when the\n CPU is onlined.\n- Disabling migration before getting the per-CPU acomp_ctx [3], but\n that\u0027s discouraged and is a much bigger hammer than needed, and could\n result in subtle performance issues.\n\n[1]https://lkml.kernel.org/20241219212437.2714151-1-yosryahmed@google.com/\n[2]https://lkml.kernel.org/20250107074724.1756696-2-yosryahmed@google.com/\n[3]https://lkml.kernel.org/20250107222236.2715883-2-yosryahmed@google.com/\n\n[yosryahmed@google.com: remove comment]"

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: ibmvfc: Store vhost pointer during subcrq allocation
Currently the back pointer from a queue to the vhost adapter isn't set
until after subcrq interrupt registration. The value is available when a
queue is first allocated and can/should be also set for primary and async
queues as well as subcrqs.
This fixes a crash observed during kexec/kdump on Power 9 with legacy XICS
interrupt controller where a pending subcrq interrupt from the previous
kernel can be replayed immediately upon IRQ registration resulting in
dereference of a garbage backpointer in ibmvfc_interrupt_scsi().
Kernel attempted to read user page (58) - exploit attempt? (uid: 0)
BUG: Kernel NULL pointer dereference on read at 0x00000058
Faulting instruction address: 0xc008000003216a08
Oops: Kernel access of bad area, sig: 11 [#1]

Summary
In the Linux kernel, the following vulnerability has been resolved:
skbuff: fix coalescing for page_pool fragment recycling
Fix a use-after-free when using page_pool with page fragments. We
encountered this problem during normal RX in the hns3 driver:
(1) Initially we have three descriptors in the RX queue. The first one
allocates PAGE1 through page_pool, and the other two allocate one
half of PAGE2 each. Page references look like this:
RX_BD1 _______ PAGE1
RX_BD2 _______ PAGE2
RX_BD3 _________/
(2) Handle RX on the first descriptor. Allocate SKB1, eventually added
to the receive queue by tcp_queue_rcv().
(3) Handle RX on the second descriptor. Allocate SKB2 and pass it to
netif_receive_skb():
netif_receive_skb(SKB2)
ip_rcv(SKB2)
SKB3 = skb_clone(SKB2)
SKB2 and SKB3 share a reference to PAGE2 through
skb_shinfo()->dataref. The other ref to PAGE2 is still held by
RX_BD3:
SKB2 ---+- PAGE2
SKB3 __/ /
RX_BD3 _________/
(3b) Now while handling TCP, coalesce SKB3 with SKB1:
tcp_v4_rcv(SKB3)
tcp_try_coalesce(to=SKB1, from=SKB3) // succeeds
kfree_skb_partial(SKB3)
skb_release_data(SKB3) // drops one dataref
SKB1 _____ PAGE1
\____
SKB2 _____ PAGE2
/
RX_BD3 _________/
In skb_try_coalesce(), __skb_frag_ref() takes a page reference to
PAGE2, where it should instead have increased the page_pool frag
reference, pp_frag_count. Without coalescing, when releasing both
SKB2 and SKB3, a single reference to PAGE2 would be dropped. Now
when releasing SKB1 and SKB2, two references to PAGE2 will be
dropped, resulting in underflow.
(3c) Drop SKB2:
af_packet_rcv(SKB2)
consume_skb(SKB2)
skb_release_data(SKB2) // drops second dataref
page_pool_return_skb_page(PAGE2) // drops one pp_frag_count
SKB1 _____ PAGE1
\____
PAGE2
/
RX_BD3 _________/
(4) Userspace calls recvmsg()
Copies SKB1 and releases it. Since SKB3 was coalesced with SKB1, we
release the SKB3 page as well:
tcp_eat_recv_skb(SKB1)
skb_release_data(SKB1)
page_pool_return_skb_page(PAGE1)
page_pool_return_skb_page(PAGE2) // drops second pp_frag_count
(5) PAGE2 is freed, but the third RX descriptor was still using it!
In our case this causes IOMMU faults, but it would silently corrupt
memory if the IOMMU was disabled.
Change the logic that checks whether pp_recycle SKBs can be coalesced.
We still reject differing pp_recycle between 'from' and 'to' SKBs, but
in order to avoid the situation described above, we also reject
coalescing when both 'from' and 'to' are pp_recycled and 'from' is
cloned.
The new logic allows coalescing a cloned pp_recycle SKB into a page
refcounted one, because in this case the release (4) will drop the right
reference, the one taken by skb_try_coalesce().

Summary
In the Linux kernel, the following vulnerability has been resolved:
thermal/core: Fix memory leak in __thermal_cooling_device_register()
I got memory leak as follows when doing fault injection test:

If device_register() fails, thermal_cooling_device_destroy_sysfs() need be called
to free the memory allocated in thermal_cooling_device_setup_sysfs().

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: Fix the maximum minor value is blk_alloc_ext_minor()
ida_alloc_range(..., min, max, ...) returns values from min to max,
inclusive.
So, NR_EXT_DEVT is a valid idx returned by blk_alloc_ext_minor().
This is an issue because in device_add_disk(), this value is used in:
ddev->devt = MKDEV(disk->major, disk->first_minor);
and NR_EXT_DEVT is '(1 << MINORBITS)'.
So, should 'disk->first_minor' be NR_EXT_DEVT, it would overflow.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gem: add missing boundary check in vm_access
A missing bounds check in vm_access() can lead to an out-of-bounds read
or write in the adjacent memory area, since the len attribute is not
validated before the memcpy later in the function, potentially hitting:

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sfp: fix memory leak in sfp_probe()
sfp_probe() allocates a memory chunk from sfp with sfp_alloc(). When
devm_add_action() fails, sfp is not freed, which leads to a memory leak.
We should use devm_add_action_or_reset() instead of devm_add_action().

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: Don't null dereference ops->destroy
A KVM device cleanup happens in either of two callbacks:
1) destroy() which is called when the VM is being destroyed;
2) release() which is called when a device fd is closed.
Most KVM devices use 1) but Book3s's interrupt controller KVM devices
(XICS, XIVE, XIVE-native) use 2) as they need to close and reopen during
the machine execution. The error handling in kvm_ioctl_create_device()
assumes destroy() is always defined which leads to NULL dereference as
discovered by Syzkaller.
This adds a checks for destroy!=NULL and adds a missing release().
This is not changing kvm_destroy_devices() as devices with defined
release() should have been removed from the KVM devices list by then.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: Fix queuing commands when HCI_UNREGISTER is set
hci_cmd_sync_queue shall return an error if HCI_UNREGISTER flag has
been set as that means hci_unregister_dev has been called so it will
likely cause a uaf after the timeout as the hdev will be freed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/virtio: Ensure that objs is not NULL in virtio_gpu_array_put_free()
If virtio_gpu_object_shmem_init() fails (e.g. due to fault injection, as it
happened in the bug report by syzbot), virtio_gpu_array_put_free() could be
called with objs equal to NULL.
Ensure that objs is not NULL in virtio_gpu_array_put_free(), or otherwise
return from the function.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/hfi1: Fix potential integer multiplication overflow errors
When multiplying of different types, an overflow is possible even when
storing the result in a larger type. This is because the conversion is
done after the multiplication. So arithmetic overflow and thus in
incorrect value is possible.
Correct an instance of this in the inter packet delay calculation. Fix by
ensuring one of the operands is u64 which will promote the other to u64 as
well ensuring no overflow.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: dlmfs: fix error handling of user_dlm_destroy_lock
When user_dlm_destroy_lock failed, it didn't clean up the flags it set
before exit. For USER_LOCK_IN_TEARDOWN, if this function fails because of
lock is still in used, next time when unlink invokes this function, it
will return succeed, and then unlink will remove inode and dentry if lock
is not in used(file closed), but the dlm lock is still linked in dlm lock
resource, then when bast come in, it will trigger a panic due to
user-after-free. See the following panic call trace. To fix this,
USER_LOCK_IN_TEARDOWN should be reverted if fail. And also error should
be returned if USER_LOCK_IN_TEARDOWN is set to let user know that unlink
fail.
For the case of ocfs2_dlm_unlock failure, besides USER_LOCK_IN_TEARDOWN,
USER_LOCK_BUSY is also required to be cleared. Even though spin lock is
released in between, but USER_LOCK_IN_TEARDOWN is still set, for
USER_LOCK_BUSY, if before every place that waits on this flag,
USER_LOCK_IN_TEARDOWN is checked to bail out, that will make sure no flow
waits on the busy flag set by user_dlm_destroy_lock(), then we can
simplely revert USER_LOCK_BUSY when ocfs2_dlm_unlock fails. Fix
user_dlm_cluster_lock() which is the only function not following this.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nocfs2: dlmfs: fix error handling of user_dlm_destroy_lock\n\nWhen user_dlm_destroy_lock failed, it didn\u0027t clean up the flags it set\nbefore exit. For USER_LOCK_IN_TEARDOWN, if this function fails because of\nlock is still in used, next time when unlink invokes this function, it\nwill return succeed, and then unlink will remove inode and dentry if lock\nis not in used(file closed), but the dlm lock is still linked in dlm lock\nresource, then when bast come in, it will trigger a panic due to\nuser-after-free. See the following panic call trace. To fix this,\nUSER_LOCK_IN_TEARDOWN should be reverted if fail. And also error should\nbe returned if USER_LOCK_IN_TEARDOWN is set to let user know that unlink\nfail.\n\nFor the case of ocfs2_dlm_unlock failure, besides USER_LOCK_IN_TEARDOWN,\nUSER_LOCK_BUSY is also required to be cleared. Even though spin lock is\nreleased in between, but USER_LOCK_IN_TEARDOWN is still set, for\nUSER_LOCK_BUSY, if before every place that waits on this flag,\nUSER_LOCK_IN_TEARDOWN is checked to bail out, that will make sure no flow\nwaits on the busy flag set by user_dlm_destroy_lock(), then we can\nsimplely revert USER_LOCK_BUSY when ocfs2_dlm_unlock fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/papr_scm: don't requests stats with '0' sized stats buffer
Sachin reported [1] that on a POWER-10 lpar he is seeing a kernel panic being
reported with vPMEM when papr_scm probe is being called. The panic is of the
form below and is observed only with following option disabled(profile) for the
said LPAR 'Enable Performance Information Collection' in the HMC:
Kernel attempted to write user page (1c) - exploit attempt? (uid: 0)
BUG: Kernel NULL pointer dereference on write at 0x0000001c

Kernel panic - not syncing: Fatal exception
On investigation looks like this panic was caused due to a 'stat_buffer' of
size==0 being provided to drc_pmem_query_stats() to fetch all performance
stats-ids of an NVDIMM. However drc_pmem_query_stats() shouldn't have been called
since the vPMEM NVDIMM doesn't support and performance stat-id's. This was caused
due to missing check for 'p->stat_buffer_len' at the beginning of
papr_scm_pmu_check_events() which indicates that the NVDIMM doesn't support
performance-stats.
Fix this by introducing the check for 'p->stat_buffer_len' at the beginning of
papr_scm_pmu_check_events().

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Fix use after free in hci_send_acl
This fixes the following trace caused by receiving
HCI_EV_DISCONN_PHY_LINK_COMPLETE which does call hci_conn_del without
first checking if conn->type is in fact AMP_LINK and in case it is
do properly cleanup upper layers with hci_disconn_cfm:

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix double free during GPU reset on DC streams
[Why]
The issue only occurs during the GPU reset code path.
We first backup the current state prior to commiting 0 streams
internally from DM to DC. This state backup contains valid link
encoder assignments.
DC will clear the link encoder assignments as part of current state
(but not the backup, since it was a copied before the commit) and
free the extra stream reference it held.
DC requires that the link encoder assignments remain cleared/invalid
prior to commiting. Since the backup still has valid assignments we
call the interface post reset to clear them. This routine also
releases the extra reference that the link encoder interface held -
resulting in a double free (and eventually a NULL pointer dereference).
[How]
We'll have to do a full DC commit anyway after GPU reset because
the stream count previously went to 0.
We don't need to retain the assignment that we had backed up, so
just copy off of the now clean current state assignment after the
reset has occcurred with the new link_enc_cfg_copy() interface.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix combination of jit blinding and pointers to bpf subprogs.
The combination of jit blinding and pointers to bpf subprogs causes:
[ 36.989548] BUG: unable to handle page fault for address: 0000000100000001
[ 36.990342] #PF: supervisor instruction fetch in kernel mode
[ 36.990968] #PF: error_code(0x0010) - not-present page
[ 36.994859] RIP: 0010:0x100000001
[ 36.995209] Code: Unable to access opcode bytes at RIP 0xffffffd7.
[ 37.004091] Call Trace:
[ 37.004351] <TASK>
[ 37.004576] ? bpf_loop+0x4d/0x70
[ 37.004932] ? bpf_prog_3899083f75e4c5de_F+0xe3/0x13b
The jit blinding logic didn't recognize that ld_imm64 with an address
of bpf subprogram is a special instruction and proceeded to randomize it.
By itself it wouldn't have been an issue, but jit_subprogs() logic
relies on two step process to JIT all subprogs and then JIT them
again when addresses of all subprogs are known.
Blinding process in the first JIT phase caused second JIT to miss
adjustment of special ld_imm64.
Fix this issue by ignoring special ld_imm64 instructions that don't have
user controlled constants and shouldn't be blinded.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ubifs: Fix read out-of-bounds in ubifs_wbuf_write_nolock()
Function ubifs_wbuf_write_nolock() may access buf out of bounds in
following process:
ubifs_wbuf_write_nolock():
aligned_len = ALIGN(len, 8); // Assume len = 4089, aligned_len = 4096
if (aligned_len <= wbuf->avail) ... // Not satisfy
if (wbuf->used) {
ubifs_leb_write() // Fill some data in avail wbuf
len -= wbuf->avail; // len is still not 8-bytes aligned
aligned_len -= wbuf->avail;
}
n = aligned_len >> c->max_write_shift;
if (n) {
n <<= c->max_write_shift;
err = ubifs_leb_write(c, wbuf->lnum, buf + written,
wbuf->offs, n);
// n > len, read out of bounds less than 8(n-len) bytes
}
, which can be catched by KASAN:

Function ubifs_wbuf_write_nolock() accepts that parameter 'len' is not 8
bytes aligned, the 'len' represents the true length of buf (which is
allocated in 'ubifs_jnl_xxx', eg. ubifs_jnl_write_inode), so
ubifs_wbuf_write_nolock() must handle the length read from 'buf' carefully
to write leb safely.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/64s: Don't use DSISR for SLB faults
Since commit 46ddcb3950a2 ("powerpc/mm: Show if a bad page fault on data
is read or write.") we use page_fault_is_write(regs->dsisr) in
__bad_page_fault() to determine if the fault is for a read or write, and
change the message printed accordingly.
But SLB faults, aka Data Segment Interrupts, don't set DSISR (Data
Storage Interrupt Status Register) to a useful value. All ISA versions
from v2.03 through v3.1 specify that the Data Segment Interrupt sets
DSISR "to an undefined value". As far as I can see there's no mention of
SLB faults setting DSISR in any BookIV content either.
This manifests as accesses that should be a read being incorrectly
reported as writes, for example, using the xmon "dump" command:
0:mon> d 0x5deadbeef0000000
5deadbeef0000000
[359526.415354][ C6] BUG: Unable to handle kernel data access on write at 0x5deadbeef0000000
[359526.415611][ C6] Faulting instruction address: 0xc00000000010a300
cpu 0x6: Vector: 380 (Data SLB Access) at [c00000000ffbf400]
pc: c00000000010a300: mread+0x90/0x190
If we disassemble the PC, we see a load instruction:
0:mon> di c00000000010a300
c00000000010a300 89490000 lbz r10,0(r9)
We can also see in exceptions-64s.S that the data_access_slb block
doesn't set IDSISR=1, which means it doesn't load DSISR into pt_regs. So
the value we're using to determine if the fault is a read/write is some
stale value in pt_regs from a previous page fault.
Rework the printing logic to separate the SLB fault case out, and only
print read/write in the cases where we can determine it.
The result looks like eg:
0:mon> d 0x5deadbeef0000000
5deadbeef0000000
[ 721.779525][ C6] BUG: Unable to handle kernel data access at 0x5deadbeef0000000

All ISA versions\nfrom v2.03 through v3.1 specify that the Data Segment Interrupt sets\nDSISR \"to an undefined value\". As far as I can see there\u0027s no mention of\nSLB faults setting DSISR in any BookIV content either.\n\nThis manifests as accesses that should be a read being incorrectly\nreported as writes, for example, using the xmon \"dump\" command:\n\n 0:mon\u003e d 0x5deadbeef0000000\n 5deadbeef0000000\n [359526.415354][ C6] BUG: Unable to handle kernel data access on write at 0x5deadbeef0000000\n [359526.415611][ C6] Faulting instruction address: 0xc00000000010a300\n cpu 0x6: Vector: 380 (Data SLB Access) at [c00000000ffbf400]\n pc: c00000000010a300: mread+0x90/0x190\n\nIf we disassemble the PC, we see a load instruction:\n\n 0:mon\u003e di c00000000010a300\n c00000000010a300 89490000 lbz r10,0(r9)\n\nWe can also see in exceptions-64s.S that the data_access_slb block\ndoesn\u0027t set IDSISR=1, which means it doesn\u0027t load DSISR into pt_regs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
partitions: mac: fix handling of bogus partition table
Fix several issues in partition probing:
- The bailout for a bad partoffset must use put_dev_sector(), since the
preceding read_part_sector() succeeded.
- If the partition table claims a silly sector size like 0xfff bytes
(which results in partition table entries straddling sector boundaries),
bail out instead of accessing out-of-bounds memory.
- We must not assume that the partition table contains proper NUL
termination - use strnlen() and strncmp() instead of strlen() and
strcmp().

Summary
In the Linux kernel, the following vulnerability has been resolved:
mfd: davinci_voicecodec: Fix possible null-ptr-deref davinci_vc_probe()
It will cause null-ptr-deref when using 'res', if platform_get_resource()
returns NULL, so move using 'res' after devm_ioremap_resource() that
will check it to avoid null-ptr-deref.
And use devm_platform_get_and_ioremap_resource() to simplify code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix potential array overflow in bpf_trampoline_get_progs()
The cnt value in the 'cnt >= BPF_MAX_TRAMP_PROGS' check does not
include BPF_TRAMP_MODIFY_RETURN bpf programs, so the number of
the attached BPF_TRAMP_MODIFY_RETURN bpf programs in a trampoline
can exceed BPF_MAX_TRAMP_PROGS.
When this happens, the assignment '*progs++ = aux->prog' in
bpf_trampoline_get_progs() will cause progs array overflow as the
progs field in the bpf_tramp_progs struct can only hold at most
BPF_MAX_TRAMP_PROGS bpf programs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSv4: Fix free of uninitialized nfs4_label on referral lookup.
Send along the already-allocated fattr along with nfs4_fs_locations, and
drop the memcpy of fattr. We end up growing two more allocations, but this
fixes up a crash as:

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: asix: add proper error handling of usb read errors
Syzbot once again hit uninit value in asix driver. The problem still the
same -- asix_read_cmd() reads less bytes, than was requested by caller.
Since all read requests are performed via asix_read_cmd() let's catch
usb related error there and add __must_check notation to be sure all
callers actually check return value.
So, this patch adds sanity check inside asix_read_cmd(), that simply
checks if bytes read are not less, than was requested and adds missing
error handling of asix_read_cmd() all across the driver code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
misc: ocxl: fix possible double free in ocxl_file_register_afu
info_release() will be called in device_unregister() when info->dev's
reference count is 0. So there is no need to call ocxl_afu_put() and
kfree() again.
Fix this by adding free_minor() and return to err_unregister error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: filter out EXT4_FC_REPLAY from on-disk superblock field s_state
The EXT4_FC_REPLAY bit in sbi->s_mount_state is used to indicate that
we are in the middle of replay the fast commit journal. This was
actually a mistake, since the sbi->s_mount_info is initialized from
es->s_state. Arguably s_mount_state is misleadingly named, but the
name is historical --- s_mount_state and s_state dates back to ext2.
What should have been used is the ext4_{set,clear,test}_mount_flag()
inline functions, which sets EXT4_MF_* bits in sbi->s_mount_flags.
The problem with using EXT4_FC_REPLAY is that a maliciously corrupted
superblock could result in EXT4_FC_REPLAY getting set in
s_mount_state. This bypasses some sanity checks, and this can trigger
a BUG() in ext4_es_cache_extent(). As a easy-to-backport-fix, filter
out the EXT4_FC_REPLAY bit for now. We should eventually transition
away from EXT4_FC_REPLAY to something like EXT4_MF_REPLAY.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix a btf decl_tag bug when tagging a function
syzbot reported a btf decl_tag bug with stack trace below:

The kasan error is triggered with an illegal BTF like below:
type 0: void
type 1: int
type 2: decl_tag to func type 3
type 3: func to func_proto type 8
The total number of types is 4 and the type 3 is illegal
since its func_proto type is out of range.
Currently, the target type of decl_tag can be struct/union, var or func.
Both struct/union and var implemented their own 'resolve' callback functions
and hence handled properly in kernel.
But func type doesn't have 'resolve' callback function. When
btf_decl_tag_resolve() tries to check func type, it tries to get
vlen of its func_proto type, which triggered the above kasan error.
To fix the issue, btf_decl_tag_resolve() needs to do btf_func_check()
before trying to accessing func_proto type.
In the current implementation, func type is checked with
btf_func_check() in the main checking function btf_check_all_types().
To fix the above kasan issue, let us implement 'resolve' callback
func type properly. The 'resolve' callback will be also called
in btf_check_all_types() for func types.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: imx-jpeg: fix a bug of accessing array out of bounds
When error occurs in parsing jpeg, the slot isn't acquired yet, it may
be the default value MXC_MAX_SLOTS.
If the driver access the slot using the incorrect slot number, it will
access array out of bounds.
The result is the driver will change num_domains, which follows
slot_data in struct mxc_jpeg_dev.
Then the driver won't detach the pm domain at rmmod, which will lead to
kernel panic when trying to insmod again.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: clear acl_access/acl_default after releasing them
If getting acl_default fails, acl_access and acl_default will be released
simultaneously. However, acl_access will still retain a pointer pointing
to the released posix_acl, which will trigger a WARNING in
nfs3svc_release_getacl like this:
------------[ cut here ]------------

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: ti: j721e-evm: Fix refcount leak in j721e_soc_probe_*
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not needed anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: usb: aqc111: Fix out-of-bounds accesses in RX fixup
aqc111_rx_fixup() contains several out-of-bounds accesses that can be
triggered by a malicious (or defective) USB device, in particular:
- The metadata array (desc_offset..desc_offset+2*pkt_count) can be out of bounds,
causing OOB reads and (on big-endian systems) OOB endianness flips.
- A packet can overlap the metadata array, causing a later OOB
endianness flip to corrupt data used by a cloned SKB that has already
been handed off into the network stack.
- A packet SKB can be constructed whose tail is far beyond its end,
causing out-of-bounds heap data to be considered part of the SKB's
data.
Found doing variant analysis. Tested it with another driver (ax88179_178a), since
I don't have a aqc111 device to test it, but the code looks very similar.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bfq: Update cgroup information before merging bio
When the process is migrated to a different cgroup (or in case of
writeback just starts submitting bios associated with a different
cgroup) bfq_merge_bio() can operate with stale cgroup information in
bic. Thus the bio can be merged to a request from a different cgroup or
it can result in merging of bfqqs for different cgroups or bfqqs of
already dead cgroups and causing possible use-after-free issues. Fix the
problem by updating cgroup information in bfq_merge_bio().

Summary
In the Linux kernel, the following vulnerability has been resolved:
LSM: general protection fault in legacy_parse_param
The usual LSM hook "bail on fail" scheme doesn't work for cases where
a security module may return an error code indicating that it does not
recognize an input. In this particular case Smack sees a mount option
that it recognizes, and returns 0. A call to a BPF hook follows, which
returns -ENOPARAM, which confuses the caller because Smack has processed
its data.
The SELinux hook incorrectly returns 1 on success. There was a time
when this was correct, however the current expectation is that it
return 0 on success. This is repaired.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ceph: fix inode reference leakage in ceph_get_snapdir()
The ceph_get_inode() will search for or insert a new inode into the
hash for the given vino, and return a reference to it. If new is
non-NULL, its reference is consumed.
We should release the reference when in error handing cases.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: soc-compress: prevent the potentially use of null pointer
There is one call trace that snd_soc_register_card()
->snd_soc_bind_card()->soc_init_pcm_runtime()
->snd_soc_dai_compress_new()->snd_soc_new_compress().
In the trace the 'codec_dai' transfers from card->dai_link,
and we can see from the snd_soc_add_pcm_runtime() in
snd_soc_bind_card() that, if value of card->dai_link->num_codecs
is 0, then 'codec_dai' could be null pointer caused
by index out of bound in 'asoc_rtd_to_codec(rtd, 0)'.
And snd_soc_register_card() is called by various platforms.
Therefore, it is better to add the check in the case of misusing.
And because 'cpu_dai' has already checked in soc_init_pcm_runtime(),
there is no need to check again.
Adding the check as follow, then if 'codec_dai' is null,
snd_soc_new_compress() will not pass through the check
'if (playback + capture != 1)', avoiding the leftover use of
'codec_dai'.

Summary
In the Linux kernel, the following vulnerability has been resolved:
jffs2: fix use-after-free in jffs2_clear_xattr_subsystem
When we mount a jffs2 image, assume that the first few blocks of
the image are normal and contain at least one xattr-related inode,
but the next block is abnormal. As a result, an error is returned
in jffs2_scan_eraseblock(). jffs2_clear_xattr_subsystem() is then
called in jffs2_build_filesystem() and then again in
jffs2_do_fill_super().
Finally we can observe the following report:
==================================================================

[...]
The buggy address belongs to the object at ffff8881243384b8
which belongs to the cache jffs2_xattr_ref of size 48
The buggy address is located 40 bytes inside of
48-byte region [ffff8881243384b8, ffff8881243384e8)
[...]
==================================================================
The triggering of the BUG is shown in the following stack:
-----------------------------------------------------------
jffs2_fill_super
jffs2_do_fill_super
jffs2_do_mount_fs
jffs2_build_filesystem
jffs2_scan_medium
jffs2_scan_eraseblock <--- ERROR
jffs2_clear_xattr_subsystem <--- free
jffs2_clear_xattr_subsystem <--- free again
-----------------------------------------------------------
An error is returned in jffs2_do_mount_fs(). If the error is returned
by jffs2_sum_init(), the jffs2_clear_xattr_subsystem() does not need to
be executed. If the error is returned by jffs2_build_filesystem(), the
jffs2_clear_xattr_subsystem() also does not need to be executed again.
So move jffs2_clear_xattr_subsystem() from 'out_inohash' to 'out_root'
to fix this UAF problem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
udmabuf: validate ubuf->pagecount
Syzbot has reported GPF in sg_alloc_append_table_from_pages(). The
problem was in ubuf->pages == ZERO_PTR.
ubuf->pagecount is calculated from arguments passed from user-space. If
user creates udmabuf with list.size == 0 then ubuf->pagecount will be
also equal to zero; it causes kmalloc_array() to return ZERO_PTR.
Fix it by validating ubuf->pagecount before passing it to
kmalloc_array().

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: atm: cxacru: fix a flaw in existing endpoint checks
Syzbot once again identified a flaw in usb endpoint checking, see [1].
This time the issue stems from a commit authored by me (2eabb655a968
("usb: atm: cxacru: fix endpoint checking in cxacru_bind()")).
While using usb_find_common_endpoints() may usually be enough to
discard devices with wrong endpoints, in this case one needs more
than just finding and identifying the sufficient number of endpoints
of correct types - one needs to check the endpoint's address as well.
Since cxacru_bind() fills URBs with CXACRU_EP_CMD address in mind,
switch the endpoint verification approach to usb_check_XXX_endpoints()
instead to fix incomplete ep testing.
[1] Syzbot report:
usb 5-1: BOGUS urb xfer, pipe 3 != type 1

Summary
In the Linux kernel, the following vulnerability has been resolved:
PM: domains: Fix sleep-in-atomic bug caused by genpd_debug_remove()
When a genpd with GENPD_FLAG_IRQ_SAFE gets removed, the following
sleep-in-atomic bug will be seen, as genpd_debug_remove() will be called
with a spinlock being held.

It doesn't seem necessary to call genpd_debug_remove() with the lock, so
move it out from locking to fix the problem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: SVM: Use kzalloc for sev ioctl interfaces to prevent kernel data leak
For some sev ioctl interfaces, the length parameter that is passed maybe
less than or equal to SEV_FW_BLOB_MAX_SIZE, but larger than the data
that PSP firmware returns. In this case, kmalloc will allocate memory
that is the size of the input rather than the size of the data.
Since PSP firmware doesn't fully overwrite the allocated buffer, these
sev ioctl interface may return uninitialized kernel slab memory.

Summary
In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v3: Fix GICR_CTLR.RWP polling
It turns out that our polling of RWP is totally wrong when checking
for it in the redistributors, as we test the *distributor* bit index,
whereas it is a different bit number in the RDs... Oopsie boo.
This is embarassing. Not only because it is wrong, but also because
it took *8 years* to notice the blunder...
Just fix the damn thing.

Summary
In the Linux kernel, the following vulnerability has been resolved:
soc: ti: ti_sci_pm_domains: Check for null return of devm_kcalloc
The allocation funciton devm_kcalloc may fail and return a null pointer,
which would cause a null-pointer dereference later.
It might be better to check it and directly return -ENOMEM just like the
usage of devm_kcalloc in previous code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: elan: Fix potential double free in elan_input_configured
'input' is a managed resource allocated with devm_input_allocate_device(),
so there is no need to call input_free_device() explicitly or
there will be a double free.
According to the doc of devm_input_allocate_device():
* Managed input devices do not need to be explicitly unregistered or
* freed as it will be done automatically when owner device unbinds from
* its driver (or binding fails).

This is due to that free_irq_cpu_rmap() is always being called
*after* (devm_)free_irq() and thus it tries to work with IRQ descs
already freed. For example, on device reset the driver frees the
rmap right before allocating a new one (the splat above).
Make rmap creation and freeing function symmetrical with
{request,free}_irq() calls i.e. do that on ifup/ifdown instead
of device probe/remove/resume. These operations can be performed
independently from the actual device aRFS configuration.
Also, make sure ice_vsi_free_irq() clears IRQ affinity notifiers
only when aRFS is disabled -- otherwise, CPU rmap sets and clears
its own and they must not be touched manually.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vfio/pci: fix memory leak during D3hot to D0 transition
If 'vfio_pci_core_device::needs_pm_restore' is set (PCI device does
not have No_Soft_Reset bit set in its PMCSR config register), then
the current PCI state will be saved locally in
'vfio_pci_core_device::pm_save' during D0->D3hot transition and same
will be restored back during D3hot->D0 transition.
For saving the PCI state locally, pci_store_saved_state() is being
used and the pci_load_and_free_saved_state() will free the allocated
memory.
But for reset related IOCTLs, vfio driver calls PCI reset-related
API's which will internally change the PCI power state back to D0. So,
when the guest resumes, then it will get the current state as D0 and it
will skip the call to vfio_pci_set_power_state() for changing the
power state to D0 explicitly. In this case, the memory pointed by
'pm_save' will never be freed. In a malicious sequence, the state changing
to D3hot followed by VFIO_DEVICE_RESET/VFIO_DEVICE_PCI_HOT_RESET can be
run in a loop and it can cause an OOM situation.
This patch frees the earlier allocated memory first before overwriting
'pm_save' to prevent the mentioned memory leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tipc: Fix use-after-free of kernel socket in cleanup_bearer().
syzkaller reported a use-after-free of UDP kernel socket
in cleanup_bearer() without repro. [0][1]
When bearer_disable() calls tipc_udp_disable(), cleanup
of the UDP kernel socket is deferred by work calling
cleanup_bearer().
tipc_exit_net() waits for such works to finish by checking
tipc_net(net)->wq_count. However, the work decrements the
count too early before releasing the kernel socket,
unblocking cleanup_net() and resulting in use-after-free.
Let's move the decrement after releasing the socket in
cleanup_bearer().

Summary
In the Linux kernel, the following vulnerability has been resolved:
igc: avoid kernel warning when changing RX ring parameters
Calling ethtool changing the RX ring parameters like this:
$ ethtool -G eth0 rx 1024
on igc triggers kernel warnings like this:

igc_ethtool_set_ringparam() copies the igc_ring structure but neglects to
reset the xdp_rxq_info member before calling igc_setup_rx_resources().
This in turn calls xdp_rxq_info_reg() with an already registered xdp_rxq_info.
Make sure to unregister the xdp_rxq_info structure first in
igc_setup_rx_resources.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/panfrost: Fix shrinker list corruption by madvise IOCTL
Calling madvise IOCTL twice on BO causes memory shrinker list corruption
and crashes kernel because BO is already on the list and it's added to
the list again, while BO should be removed from the list before it's
re-added. Fix it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
video: fbdev: nvidiafb: Use strscpy() to prevent buffer overflow
Coverity complains of a possible buffer overflow. However,
given the 'static' scope of nvidia_setup_i2c_bus() it looks
like that can't happen after examiniing the call sites.
CID 19036 (#1 of 1): Copy into fixed size buffer (STRING_OVERFLOW)
1. fixed_size_dest: You might overrun the 48-character fixed-size string
chan->adapter.name by copying name without checking the length.
2. parameter_as_source: Note: This defect has an elevated risk because the
source argument is a parameter of the current function.
89 strcpy(chan->adapter.name, name);
Fix this warning by using strscpy() which will silence the warning and
prevent any future buffer overflows should the names used to identify the
channel become much longer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: Fix unregistering of framebuffers without device
OF framebuffers do not have an underlying device in the Linux
device hierarchy. Do a regular unregister call instead of hot
unplugging such a non-existing device. Fixes a NULL dereference.
An example error message on ppc64le is shown below.

The bug [1] was introduced by commit 27599aacbaef ("fbdev: Hot-unplug
firmware fb devices on forced removal"). Most firmware framebuffers
have an underlying platform device, which can be hot-unplugged
before loading the native graphics driver. OF framebuffers do not
(yet) have that device. Fix the code by unregistering the framebuffer
as before without a hot unplug.
Tested with 5.17 on qemu ppc64le emulation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usbnet: Run unregister_netdev() before unbind() again
Commit 2c9d6c2b871d ("usbnet: run unbind() before unregister_netdev()")
sought to fix a use-after-free on disconnect of USB Ethernet adapters.
It turns out that a different fix is necessary to address the issue:
https://lore.kernel.org/netdev/18b3541e5372bc9b9fc733d422f4e698c089077c.1650177997.git.lukas@wunner.de/
So the commit was not necessary.
The commit made binding and unbinding of USB Ethernet asymmetrical:
Before, usbnet_probe() first invoked the ->bind() callback and then
register_netdev(). usbnet_disconnect() mirrored that by first invoking
unregister_netdev() and then ->unbind().
Since the commit, the order in usbnet_disconnect() is reversed and no
longer mirrors usbnet_probe().
One consequence is that a PHY disconnected (and stopped) in ->unbind()
is afterwards stopped once more by unregister_netdev() as it closes the
netdev before unregistering. That necessitates a contortion in ->stop()
because the PHY may only be stopped if it hasn't already been
disconnected.
Reverting the commit allows making the call to phy_stop() unconditional
in ->stop().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: imx-hdmi: Fix refcount leak in imx_hdmi_probe
of_find_device_by_node() takes reference, we should use put_device()
to release it. when devm_kzalloc() fails, it doesn't have a
put_device(), it will cause refcount leak.
Add missing put_device() to fix this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tpm: use try_get_ops() in tpm-space.c
As part of the series conversion to remove nested TPM operations:
https://lore.kernel.org/all/20190205224723.19671-1-jarkko.sakkinen@linux.intel.com/
exposure of the chip->tpm_mutex was removed from much of the upper
level code. In this conversion, tpm2_del_space() was missed. This
didn't matter much because it's usually called closely after a
converted operation, so there's only a very tiny race window where the
chip can be removed before the space flushing is done which causes a
NULL deref on the mutex. However, there are reports of this window
being hit in practice, so fix this by converting tpm2_del_space() to
use tpm_try_get_ops(), which performs all the teardown checks before
acquring the mutex.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tick/nohz: unexport __init-annotated tick_nohz_full_setup()
EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.
modpost used to detect it, but it had been broken for a decade.
Commit 28438794aba4 ("modpost: fix section mismatch check for exported
init/exit sections") fixed it so modpost started to warn it again, then
this showed up:
MODPOST vmlinux.symvers
WARNING: modpost: vmlinux.o(___ksymtab_gpl+tick_nohz_full_setup+0x0): Section mismatch in reference from the variable __ksymtab_tick_nohz_full_setup to the function .init.text:tick_nohz_full_setup()
The symbol tick_nohz_full_setup is exported and annotated __init
Fix this by removing the __init annotation of tick_nohz_full_setup or drop the export.
Drop the export because tick_nohz_full_setup() is only called from the
built-in code in kernel/sched/isolation.c.

Summary
In the Linux kernel, the following vulnerability has been resolved:
power/reset: arm-versatile: Fix refcount leak in versatile_reboot_probe
of_find_matching_node_and_match() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: betop: check shape of output reports
betopff_init() only checks the total sum of the report counts for each
report field to be at least 4, but hid_betopff_play() expects 4 report
fields.
A device advertising an output report with one field and 4 report counts
would pass the check but crash the kernel with a NULL pointer dereference
in hid_betopff_play().

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: atlantic: remove aq_nic_deinit() when resume
aq_nic_deinit() has been called while suspending, so we don't have to call
it again on resume.
Actually, call it again leads to another hang issue when resuming from
S3.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sfc: fix considering that all channels have TX queues
Normally, all channels have RX and TX queues, but this is not true if
modparam efx_separate_tx_channels=1 is used. In that cases, some
channels only have RX queues and others only TX queues (or more
preciselly, they have them allocated, but not initialized).
Fix efx_channel_has_tx_queues to return the correct value for this case
too.
Messages shown at probe time before the fix:

Summary
In the Linux kernel, the following vulnerability has been resolved:
soc: rockchip: Fix refcount leak in rockchip_grf_init
of_find_matching_node_and_match returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vc_screen: move load of struct vc_data pointer in vcs_read() to avoid UAF
After a call to console_unlock() in vcs_read() the vc_data struct can be
freed by vc_deallocate(). Because of that, the struct vc_data pointer
load must be done at the top of while loop in vcs_read() to avoid a UAF
when vcs_size() is called.
Syzkaller reported a UAF in vcs_size().

Summary
In the Linux kernel, the following vulnerability has been resolved:
mac80211: fix potential double free on mesh join
While commit 6a01afcf8468 ("mac80211: mesh: Free ie data when leaving
mesh") fixed a memory leak on mesh leave / teardown it introduced a
potential memory corruption caused by a double free when rejoining the
mesh:
ieee80211_leave_mesh()
-> kfree(sdata->u.mesh.ie);
...
ieee80211_join_mesh()
-> copy_mesh_setup()
-> old_ie = ifmsh->ie;
-> kfree(old_ie);
This double free / kernel panics can be reproduced by using wpa_supplicant
with an encrypted mesh (if set up without encryption via "iw" then
ifmsh->ie is always NULL, which avoids this issue). And then calling:
$ iw dev mesh0 mesh leave
$ iw dev mesh0 mesh join my-mesh
Note that typically these commands are not used / working when using
wpa_supplicant. And it seems that wpa_supplicant or wpa_cli are going
through a NETDEV_DOWN/NETDEV_UP cycle between a mesh leave and mesh join
where the NETDEV_UP resets the mesh.ie to NULL via a memcpy of
default_mesh_setup in cfg80211_netdev_notifier_call, which then avoids
the memory corruption, too.
The issue was first observed in an application which was not using
wpa_supplicant but "Senf" instead, which implements its own calls to
nl80211.
Fixing the issue by removing the kfree()'ing of the mesh IE in the mesh
join function and leaving it solely up to the mesh leave to free the
mesh IE.

And then calling:\n\n $ iw dev mesh0 mesh leave\n $ iw dev mesh0 mesh join my-mesh\n\nNote that typically these commands are not used / working when using\nwpa_supplicant. And it seems that wpa_supplicant or wpa_cli are going\nthrough a NETDEV_DOWN/NETDEV_UP cycle between a mesh leave and mesh join\nwhere the NETDEV_UP resets the mesh.ie to NULL via a memcpy of\ndefault_mesh_setup in cfg80211_netdev_notifier_call, which then avoids\nthe memory corruption, too.\n\nThe issue was first observed in an application which was not using\nwpa_supplicant but \"Senf\" instead, which implements its own calls to\nnl80211.\n\nFixing the issue by removing the kfree()\u0027ing of the mesh IE in the mesh\njoin function and leaving it solely up to the mesh leave to free the\nmesh IE."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix request_sock leak in sk lookup helpers
A customer reported a request_socket leak in a Calico cloud environment. We
found that a BPF program was doing a socket lookup with takes a refcnt on
the socket and that it was finding the request_socket but returning the parent
LISTEN socket via sk_to_full_sk() without decrementing the child request socket
1st, resulting in request_sock slab object leak. This patch retains the
existing behaviour of returning full socks to the caller but it also decrements
the child request_socket if one is present before doing so to prevent the leak.
Thanks to Curtis Taylor for all the help in diagnosing and testing this. And
thanks to Antoine Tenart for the reproducer and patch input.
v2 of this patch contains, refactor as per Daniel Borkmann's suggestions to
validate RCU flags on the listen socket so that it balances with bpf_sk_release()
and update comments as per Martin KaFai Lau's suggestion. One small change to
Daniels suggestion, put "sk = sk2" under "if (sk2 != sk)" to avoid an extra
instruction.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix potential NULL pointer dereference in atomctrl_get_smc_sclk_range_table
The function atomctrl_get_smc_sclk_range_table() does not check the return
value of smu_atom_get_data_table(). If smu_atom_get_data_table() fails to
retrieve SMU_Info table, it returns NULL which is later dereferenced.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
In practice this should never happen as this code only gets called
on polaris chips and the vbios data table will always be present on
those chips.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/mdp4: Fix refcount leak in mdp4_modeset_init_intf
of_graph_get_remote_node() returns remote device node pointer with
refcount incremented, we should use of_node_put() on it
when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: pm8001: Fix abort all task initialization
In pm80xx_send_abort_all(), the n_elem field of the ccb used is not
initialized to 0. This missing initialization sometimes lead to the task
completion path seeing the ccb with a non-zero n_elem resulting in the
execution of invalid dma_unmap_sg() calls in pm8001_ccb_task_free(),
causing a crash such as:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: ipc3-topology: Correct get_control_data for non bytes payload
It is possible to craft a topology where sof_get_control_data() would do
out of bounds access because it expects that it is only called when the
payload is bytes type.
Confusingly it also handles other types of controls, but the payload
parsing implementation is only valid for bytes.
Fix the code to count the non bytes controls and instead of storing a
pointer to sof_abi_hdr in sof_widget_data (which is only valid for bytes),
store the pointer to the data itself and add a new member to save the size
of the data.
In case of non bytes controls we store the pointer to the chanv itself,
which is just an array of values at the end.
In case of bytes control, drop the wrong cdata->data (wdata[i].pdata) check
against NULL since it is incorrect and invalid in this context.
The data is pointing to the end of cdata struct, so it should never be
null.

In the Linux kernel, the following vulnerability has been resolved:
mmc: jz4740: Apply DMA engine limits to maximum segment size
Do what is done in other DMA-enabled MMC host drivers (cf. host/mmci.c) and
limit the maximum segment size based on the DMA engine's capabilities. This
is needed to avoid warnings like the following with CONFIG_DMA_API_DEBUG=y.

Summary
In the Linux kernel, the following vulnerability has been resolved:
driver core: Fix wait_for_device_probe() & deferred_probe_timeout interaction
Mounting NFS rootfs was timing out when deferred_probe_timeout was
non-zero [1]. This was because ip_auto_config() initcall times out
waiting for the network interfaces to show up when
deferred_probe_timeout was non-zero. While ip_auto_config() calls
wait_for_device_probe() to make sure any currently running deferred
probe work or asynchronous probe finishes, that wasn't sufficient to
account for devices being deferred until deferred_probe_timeout.
Commit 35a672363ab3 ("driver core: Ensure wait_for_device_probe() waits
until the deferred_probe_timeout fires") tried to fix that by making
sure wait_for_device_probe() waits for deferred_probe_timeout to expire
before returning.
However, if wait_for_device_probe() is called from the kernel_init()
context:
- Before deferred_probe_initcall() [2], it causes the boot process to
hang due to a deadlock.
- After deferred_probe_initcall() [3], it blocks kernel_init() from
continuing till deferred_probe_timeout expires and beats the point of
deferred_probe_timeout that's trying to wait for userspace to load
modules.
Neither of this is good. So revert the changes to
wait_for_device_probe().

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: remove two BUG() from skb_checksum_help()
I have a syzbot report that managed to get a crash in skb_checksum_help()
If syzbot can trigger these BUG(), it makes sense to replace
them with more friendly WARN_ON_ONCE() since skb_checksum_help()
can instead return an error code.
Note that syzbot will still crash there, until real bug is fixed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ARM: davinci: da850-evm: Avoid NULL pointer dereference
With newer versions of GCC, there is a panic in da850_evm_config_emac()
when booting multi_v5_defconfig in QEMU under the palmetto-bmc machine:
Unable to handle kernel NULL pointer dereference at virtual address 00000020
pgd = (ptrval)
[00000020] *pgd=00000000
Internal error: Oops: 5 [#1] PREEMPT ARM
Modules linked in:
CPU: 0 PID: 1 Comm: swapper Not tainted 5.15.0 #1
Hardware name: Generic DT based system
PC is at da850_evm_config_emac+0x1c/0x120
LR is at do_one_initcall+0x50/0x1e0
The emac_pdata pointer in soc_info is NULL because davinci_soc_info only
gets populated on davinci machines but da850_evm_config_emac() is called
on all machines via device_initcall().
Move the rmii_en assignment below the machine check so that it is only
dereferenced when running on a supported SoC.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ubi: ubi_create_volume: Fix use-after-free when volume creation failed
There is an use-after-free problem for 'eba_tbl' in ubi_create_volume()'s
error handling path:
ubi_eba_replace_table(vol, eba_tbl)
vol->eba_tbl = tbl
out_mapping:
ubi_eba_destroy_table(eba_tbl) // Free 'eba_tbl'
out_unlock:
put_device(&vol->dev)
vol_release
kfree(tbl->entries) // UAF
Fix it by removing redundant 'eba_tbl' releasing.
Fetch a reproducer in [Link].

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/pseries: Fix use after free in remove_phb_dynamic()
In remove_phb_dynamic() we use &phb->io_resource, after we've called
device_unregister(&host_bridge->dev). But the unregister may have freed
phb, because pcibios_free_controller_deferred() is the release function
for the host_bridge.
If there are no outstanding references when we call device_unregister()
then phb will be freed out from under us.
This has gone mainly unnoticed, but with slub_debug and page_poison
enabled it can lead to a crash:

To avoid it, we can take a reference to the host_bridge->dev until we're
done using phb. Then when we drop the reference the phb will be freed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: cacheinfo: Avoid out-of-bounds write to cacheinfo array
The loop that detects/populates cache information already has a bounds
check on the array size but does not account for cache levels with
separate data/instructions cache. Fix this by incrementing the index
for any populated leaf (instead of any populated level).

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/i8259: Mark legacy PIC interrupts with IRQ_LEVEL
Baoquan reported that after triggering a crash the subsequent crash-kernel
fails to boot about half of the time. It triggers a NULL pointer
dereference in the periodic tick code.
This happens because the legacy timer interrupt (IRQ0) is resent in
software which happens in soft interrupt (tasklet) context. In this context
get_irq_regs() returns NULL which leads to the NULL pointer dereference.
The reason for the resend is a spurious APIC interrupt on the IRQ0 vector
which is captured and leads to a resend when the legacy timer interrupt is
enabled. This is wrong because the legacy PIC interrupts are level
triggered and therefore should never be resent in software, but nothing
ever sets the IRQ_LEVEL flag on those interrupts, so the core code does not
know about their trigger type.
Ensure that IRQ_LEVEL is set when the legacy PCI interrupts are set up.

Above issue may happen as follows:
-------------------------------------
ext4_fill_super
ext4_enable_quotas
ext4_quota_enable
ext4_iget
__ext4_iget
ext4_ext_check_inode
ext4_ext_check
__ext4_ext_check
ext4_valid_extent_entries
Check for overlapping extents does't take effect
dquot_enable
vfs_load_quota_inode
v2_check_quota_file
v2_read_header
ext4_quota_read
ext4_bread
ext4_getblk
ext4_map_blocks
ext4_ext_map_blocks
ext4_find_extent
ext4_cache_extents
ext4_es_cache_extent
ext4_es_cache_extent
__es_tree_search
ext4_es_end
BUG_ON(es->es_lblk + es->es_len < es->es_lblk)
The error ext4 extents is as follows:
0af3 0300 0400 0000 00000000 extent_header
00000000 0100 0000 12000000 extent1
00000000 0100 0000 18000000 extent2
02000000 0400 0000 14000000 extent3
In the ext4_valid_extent_entries function,
if prev is 0, no error is returned even if lblock<=prev.
This was intended to skip the check on the first extent, but
in the error image above, prev=0+1-1=0 when checking the second extent,
so even though lblock<=prev, the function does not return an error.
As a result, bug_ON occurs in __es_tree_search and the system panics.
To solve this problem, we only need to check that:
1. The lblock of the first extent is not less than 0.
2. The lblock of the next extent is not less than
the next block of the previous extent.
The same applies to extent_idx.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/a6xx: Fix refcount leak in a6xx_gpu_init
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
a6xx_gmu_init() passes the node to of_find_device_by_node()
and of_dma_configure(), of_find_device_by_node() will takes its
reference, of_dma_configure() doesn't need the node after usage.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: cs35l41: Fix an out-of-bounds access in otp_packed_element_t
The CS35L41_NUM_OTP_ELEM is 100, but only 99 entries are defined in
the array otp_map_1/2[CS35L41_NUM_OTP_ELEM], this will trigger UBSAN
to report a shift-out-of-bounds warning in the cs35l41_otp_unpack()
since the last entry in the array will result in GENMASK(-1, 0).
UBSAN reports this problem:
UBSAN: shift-out-of-bounds in /home/hwang4/build/jammy/jammy/sound/soc/codecs/cs35l41-lib.c:836:8
shift exponent 64 is too large for 64-bit type 'long unsigned int'

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: Fix slab-use-after-free Read in l2cap_send_cmd
After the hci sync command releases l2cap_conn, the hci receive data work
queue references the released l2cap_conn when sending to the upper layer.
Add hci dev lock to the hci receive data work queue to synchronize the two.
[1]

Summary
In the Linux kernel, the following vulnerability has been resolved:
veth: Ensure eth header is in skb's linear part
After feeding a decapsulated packet to a veth device with act_mirred,
skb_headlen() may be 0. But veth_xmit() calls __dev_forward_skb(),
which expects at least ETH_HLEN byte of linear data (as
__dev_forward_skb2() calls eth_type_trans(), which pulls ETH_HLEN bytes
unconditionally).
Use pskb_may_pull() to ensure veth_xmit() respects this constraint.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: mcast: extend RCU protection in igmp6_send()
igmp6_send() can be called without RTNL or RCU being held.
Extend RCU protection so that we can safely fetch the net pointer
and avoid a potential UAF.
Note that we no longer can use sock_alloc_send_skb() because
ipv6.igmp_sk uses GFP_KERNEL allocations which can sleep.
Instead use alloc_skb() and charge the net->ipv6.igmp_sk
socket under RCU protection.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netlink: prevent potential spectre v1 gadgets
Most netlink attributes are parsed and validated from
__nla_validate_parse() or validate_nla()
u16 type = nla_type(nla);
if (type == 0 || type > maxtype) {
/* error or continue */
}
@type is then used as an array index and can be used
as a Spectre v1 gadget.
array_index_nospec() can be used to prevent leaking
content of kernel memory to malicious users.
This should take care of vast majority of netlink uses,
but an audit is needed to take care of others where
validation is not yet centralized in core netlink functions.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mt76: mt7921: fix crash when startup fails.
If the nic fails to start, it is possible that the
reset_work has already been scheduled. Ensure the
work item is canceled so we do not have use-after-free
crash in case cleanup is called before the work item
is executed.
This fixes crash on my x86_64 apu2 when mt7921k radio
fails to work. Radio still fails, but OS does not
crash.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: fix removing a namespace with conflicting altnames
Mark reports a BUG() when a net namespace is removed.
kernel BUG at net/core/dev.c:11520!
Physical interfaces moved outside of init_net get "refunded"
to init_net when that namespace disappears. The main interface
name may get overwritten in the process if it would have
conflicted. We need to also discard all conflicting altnames.
Recent fixes addressed ensuring that altnames get moved
with the main interface, which surfaced this problem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers: staging: rtl8192e: Fix deadlock in rtllib_beacons_stop()
There is a deadlock in rtllib_beacons_stop(), which is shown
below:
(Thread 1) | (Thread 2)
| rtllib_send_beacon()
rtllib_beacons_stop() | mod_timer()
spin_lock_irqsave() //(1) | (wait a time)
... | rtllib_send_beacon_cb()
del_timer_sync() | spin_lock_irqsave() //(2)
(wait timer to stop) | ...
We hold ieee->beacon_lock in position (1) of thread 1 and
use del_timer_sync() to wait timer to stop, but timer handler
also need ieee->beacon_lock in position (2) of thread 2.
As a result, rtllib_beacons_stop() will block forever.
This patch extracts del_timer_sync() from the protection of
spin_lock_irqsave(), which could let timer handler to obtain
the needed lock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v3: Fix refcount leak in gic_populate_ppi_partitions
of_find_node_by_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: pci: cx23885: Fix the error handling in cx23885_initdev()
When the driver fails to call the dma_set_mask(), the driver will get
the following splat:
[ 55.853884] BUG: KASAN: use-after-free in __process_removed_driver+0x3c/0x240
[ 55.854486] Read of size 8 at addr ffff88810de60408 by task modprobe/590
[ 55.856822] Call Trace:
[ 55.860327] __process_removed_driver+0x3c/0x240
[ 55.861347] bus_for_each_dev+0x102/0x160
[ 55.861681] i2c_del_driver+0x2f/0x50
This is because the driver has initialized the i2c related resources
in cx23885_dev_setup() but not released them in error handling, fix this
bug by modifying the error path that jumps after failing to call the
dma_set_mask().

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm mirror log: round up region bitmap size to BITS_PER_LONG
The code in dm-log rounds up bitset_size to 32 bits. It then uses
find_next_zero_bit_le on the allocated region. find_next_zero_bit_le
accesses the bitmap using unsigned long pointers. So, on 64-bit
architectures, it may access 4 bytes beyond the allocated size.
Fix this bug by rounding up bitset_size to BITS_PER_LONG.
This bug was found by running the lvm2 testsuite with kasan.

Summary
In the Linux kernel, the following vulnerability has been resolved:
extcon: Modify extcon device to be created after driver data is set
Currently, someone can invoke the sysfs such as state_show()
intermittently before dev_set_drvdata() is done.
And it can be a cause of kernel Oops because of edev is Null at that time.
So modified the driver registration to after setting drviver data.
- Oops's backtrace.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bcache: avoid journal no-space deadlock by reserving 1 journal bucket
The journal no-space deadlock was reported time to time. Such deadlock
can happen in the following situation.
When all journal buckets are fully filled by active jset with heavy
write I/O load, the cache set registration (after a reboot) will load
all active jsets and inserting them into the btree again (which is
called journal replay). If a journaled bkey is inserted into a btree
node and results btree node split, new journal request might be
triggered. For example, the btree grows one more level after the node
split, then the root node record in cache device super block will be
upgrade by bch_journal_meta() from bch_btree_set_root(). But there is no
space in journal buckets, the journal replay has to wait for new journal
bucket to be reclaimed after at least one journal bucket replayed. This
is one example that how the journal no-space deadlock happens.
The solution to avoid the deadlock is to reserve 1 journal bucket in
run time, and only permit the reserved journal bucket to be used during
cache set registration procedure for things like journal replay. Then
the journal space will never be fully filled, there is no chance for
journal no-space deadlock to happen anymore.
This patch adds a new member "bool do_reserve" in struct journal, it is
inititalized to 0 (false) when struct journal is allocated, and set to
1 (true) by bch_journal_space_reserve() when all initialization done in
run_cache_set(). In the run time when journal_reclaim() tries to
allocate a new journal bucket, free_journal_buckets() is called to check
whether there are enough free journal buckets to use. If there is only
1 free journal bucket and journal->do_reserve is 1 (true), the last
bucket is reserved and free_journal_buckets() will return 0 to indicate
no free journal bucket. Then journal_reclaim() will give up, and try
next time to see whetheer there is free journal bucket to allocate. By
this method, there is always 1 jouranl bucket reserved in run time.
During the cache set registration, journal->do_reserve is 0 (false), so
the reserved journal bucket can be used to avoid the no-space deadlock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix a NULL pointer dereference in amdgpu_dm_connector_add_common_modes()
In amdgpu_dm_connector_add_common_modes(), amdgpu_dm_create_common_mode()
is assigned to mode and is passed to drm_mode_probed_add() directly after
that. drm_mode_probed_add() passes &mode->head to list_add_tail(), and
there is a dereference of it in list_add_tail() without recoveries, which
could lead to NULL pointer dereference on failure of
amdgpu_dm_create_common_mode().
Fix this by adding a NULL check of mode.
This bug was found by a static analyzer.
Builds with 'make allyesconfig' show no new warnings,
and our static analyzer no longer warns about this code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: Avoid pci_dev_lock() AB/BA deadlock with sriov_numvfs_store()
The sysfs sriov_numvfs_store() path acquires the device lock before the
config space access lock:
sriov_numvfs_store
device_lock # A (1) acquire device lock
sriov_configure
vfio_pci_sriov_configure # (for example)
vfio_pci_core_sriov_configure
pci_disable_sriov
sriov_disable
pci_cfg_access_lock
pci_wait_cfg # B (4) wait for dev->block_cfg_access == 0
Previously, pci_dev_lock() acquired the config space access lock before the
device lock:
pci_dev_lock
pci_cfg_access_lock
dev->block_cfg_access = 1 # B (2) set dev->block_cfg_access = 1
device_lock # A (3) wait for device lock
Any path that uses pci_dev_lock(), e.g., pci_reset_function(), may
deadlock with sriov_numvfs_store() if the operations occur in the sequence
(1) (2) (3) (4).
Avoid the deadlock by reversing the order in pci_dev_lock() so it acquires
the device lock before the config space access lock, the same as the
sriov_numvfs_store() path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix race condition between ext4_write and ext4_convert_inline_data
Hulk Robot reported a BUG_ON:
==================================================================
EXT4-fs error (device loop3): ext4_mb_generate_buddy:805: group 0,

handle=NULL
ext4_journal_stop(handle)
__ext4_journal_stop
ext4_put_nojournal(handle)
ref_cnt = (unsigned long)handle
BUG_ON(ref_cnt == 0) ---> BUG_ON
The lock held by ext4_convert_inline_data is xattr_sem, but the lock
held by generic_perform_write is i_rwsem. Therefore, the two locks can
be concurrent.
To solve above issue, we add inode_lock() for ext4_convert_inline_data().
At the same time, move ext4_convert_inline_data() in front of
ext4_punch_hole(), remove similar handling from ext4_punch_hole().

Summary
In the Linux kernel, the following vulnerability has been resolved:
wireguard: socket: free skb in send6 when ipv6 is disabled
I got a memory leak report:
unreferenced object 0xffff8881191fc040 (size 232):
comm "kworker/u17:0", pid 23193, jiffies 4295238848 (age 3464.870s)
hex dump (first 32 bytes):

In function wg_socket_send_buffer_as_reply_to_skb() or wg_socket_send_
buffer_to_peer(), the semantics of send6() is required to free skb. But
when CONFIG_IPV6 is disable, kfree_skb() is missing. This patch adds it
to fix this bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
driver: base: fix UAF when driver_attach failed
When driver_attach(drv); failed, the driver_private will be freed.
But it has been added to the bus, which caused a UAF.
To fix it, we need to delete it from the bus when failed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: hub: Ignore non-compliant devices with too many configs or interfaces
Robert Morris created a test program which can cause
usb_hub_to_struct_hub() to dereference a NULL or inappropriate
pointer:
Oops: general protection fault, probably for non-canonical address
0xcccccccccccccccc: 0000 [#1] SMP DEBUG_PAGEALLOC PTI
CPU: 7 UID: 0 PID: 117 Comm: kworker/7:1 Not tainted 6.13.0-rc3-00017-gf44d154d6e3d #14

Workqueue: usb_hub_wq hub_event

The cause of this error is that the device has two interfaces, and the
hub driver binds to interface 1 instead of interface 0, which is where
usb_hub_to_struct_hub() looks.
We can prevent the problem from occurring by refusing to accept hub
devices that violate the USB spec by having more than one
configuration or interface.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tty: fix deadlock caused by calling printk() under tty_port->lock
pty_write() invokes kmalloc() which may invoke a normal printk() to print
failure message. This can cause a deadlock in the scenario reported by
syz-bot below:
CPU0 CPU1 CPU2
---- ---- ----
lock(console_owner);
lock(&port_lock_key);
lock(&port->lock);
lock(&port_lock_key);
lock(&port->lock);
lock(console_owner);
As commit dbdda842fe96 ("printk: Add console owner and waiter logic to
load balance console writes") said, such deadlock can be prevented by
using printk_deferred() in kmalloc() (which is invoked in the section
guarded by the port->lock). But there are too many printk() on the
kmalloc() path, and kmalloc() can be called from anywhere, so changing
printk() to printk_deferred() is too complicated and inelegant.
Therefore, this patch chooses to specify __GFP_NOWARN to kmalloc(), so
that printk() will not be called, and this deadlock problem can be
avoided.
Syzbot reported the following lockdep error:

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSv4.2: fix reference count leaks in _nfs42_proc_copy_notify()
[You don't often get email from xiongx18@fudan.edu.cn. Learn why this is important at http://aka.ms/LearnAboutSenderIdentification.]
The reference counting issue happens in two error paths in the
function _nfs42_proc_copy_notify(). In both error paths, the function
simply returns the error code and forgets to balance the refcount of
object `ctx`, bumped by get_nfs_open_context() earlier, which may
cause refcount leaks.
Fix it by balancing refcount of the `ctx` object before the function
returns in both error paths.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: fix handlecache and multiuser
In multiuser each individual user has their own tcon structure for the
share and thus their own handle for a cached directory.
When we umount such a share we much make sure to release the pinned down dentry
for each such tcon and not just the master tcon.
Otherwise we will get nasty warnings on umount that dentries are still in use:
[ 3459.590047] BUG: Dentry 00000000115c6f41{i=12000000019d95,n=/} still in use\

Summary
In the Linux kernel, the following vulnerability has been resolved:
md/bitmap: don't set sb values if can't pass sanity check
If bitmap area contains invalid data, kernel will crash then mdadm
triggers "Segmentation fault".
This is cluster-md speical bug. In non-clustered env, mdadm will
handle broken metadata case. In clustered array, only kernel space
handles bitmap slot info. But even this bug only happened in clustered
env, current sanity check is wrong, the code should be changed.
How to trigger: (faulty injection)
dd if=/dev/zero bs=1M count=1 oflag=direct of=/dev/sda
dd if=/dev/zero bs=1M count=1 oflag=direct of=/dev/sdb
mdadm -C /dev/md0 -b clustered -e 1.2 -n 2 -l mirror /dev/sda /dev/sdb
mdadm -Ss
echo aaa > magic.txt
== below modifying slot 2 bitmap data ==
dd if=magic.txt of=/dev/sda seek=16384 bs=1 count=3 <== destroy magic
dd if=/dev/zero of=/dev/sda seek=16436 bs=1 count=4 <== ZERO chunksize
mdadm -A /dev/md0 /dev/sda /dev/sdb
== kernel crashes. mdadm outputs "Segmentation fault" ==
Reason of kernel crash:
In md_bitmap_read_sb (called by md_bitmap_create), bad bitmap magic didn't
block chunksize assignment, and zero value made DIV_ROUND_UP_SECTOR_T()
trigger "divide error".
Crash log:

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/panel: ili9341: fix optional regulator handling
If the optional regulator lookup fails, reset the pointer to NULL.
Other functions such as mipi_dbi_poweron_reset_conditional() only do
a NULL pointer check and will otherwise dereference the error pointer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/rdmavt: add lock to call to rvt_error_qp to prevent a race condition
The documentation of the function rvt_error_qp says both r_lock and s_lock
need to be held when calling that function. It also asserts using lockdep
that both of those locks are held. However, the commit I referenced in
Fixes accidentally makes the call to rvt_error_qp in rvt_ruc_loopback no
longer covered by r_lock. This results in the lockdep assertion failing
and also possibly in a race condition.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix ext4_mb_mark_bb() with flex_bg with fast_commit
In case of flex_bg feature (which is by default enabled), extents for
any given inode might span across blocks from two different block group.
ext4_mb_mark_bb() only reads the buffer_head of block bitmap once for the
starting block group, but it fails to read it again when the extent length
boundary overflows to another block group. Then in this below loop it
accesses memory beyond the block group bitmap buffer_head and results
into a data abort.
for (i = 0; i < clen; i++)
if (!mb_test_bit(blkoff + i, bitmap_bh->b_data) == !state)
already++;
This patch adds this functionality for checking block group boundary in
ext4_mb_mark_bb() and update the buffer_head(bitmap_bh) for every different
block group.
w/o this patch, I was easily able to hit a data access abort using Power platform.

Summary
In the Linux kernel, the following vulnerability has been resolved:
soc: qcom: rpmpd: Check for null return of devm_kcalloc
Because of the possible failure of the allocation, data->domains might
be NULL pointer and will cause the dereference of the NULL pointer
later.
Therefore, it might be better to check it and directly return -ENOMEM
without releasing data manually if fails, because the comment of the
devm_kmalloc() says "Memory allocated with this function is
automatically freed on driver detach.".

Summary
In the Linux kernel, the following vulnerability has been resolved:
ibmvnic: fix race between xmit and reset
There is a race between reset and the transmit paths that can lead to
ibmvnic_xmit() accessing an scrq after it has been freed in the reset
path. It can result in a crash like:

The immediate cause of the crash is the access of tx_scrq in the following
snippet during a reset, where the tx_scrq can be either NULL or an address
that will soon be invalid:
ibmvnic_xmit()
{
...
tx_scrq = adapter->tx_scrq[queue_num];
txq = netdev_get_tx_queue(netdev, queue_num);
ind_bufp = &tx_scrq->ind_buf;
if (test_bit(0, &adapter->resetting)) {
...
}
But beyond that, the call to ibmvnic_xmit() itself is not safe during a
reset and the reset path attempts to avoid this by stopping the queue in
ibmvnic_cleanup(). However just after the queue was stopped, an in-flight
ibmvnic_complete_tx() could have restarted the queue even as the reset is
progressing.
Since the queue was restarted we could get a call to ibmvnic_xmit() which
can then access the bad tx_scrq (or other fields).
We cannot however simply have ibmvnic_complete_tx() check the ->resetting
bit and skip starting the queue. This can race at the "back-end" of a good
reset which just restarted the queue but has not cleared the ->resetting
bit yet. If we skip restarting the queue due to ->resetting being true,
the queue would remain stopped indefinitely potentially leading to transmit
timeouts.
IOW ->resetting is too broad for this purpose. Instead use a new flag
that indicates whether or not the queues are active. Only the open/
reset paths control when the queues are active. ibmvnic_complete_tx()
and others wake up the queue only if the queue is marked active.
So we will have:
A. reset/open thread in ibmvnic_cleanup() and __ibmvnic_open()
->resetting = true
->tx_queues_active = false
disable tx queues
...
->tx_queues_active = true
start tx queues
B. Tx interrupt in ibmvnic_complete_tx():
if (->tx_queues_active)
netif_wake_subqueue();
To ensure that ->tx_queues_active and state of the queues are consistent,
we need a lock which:
- must also be taken in the interrupt path (ibmvnic_complete_tx())
- shared across the multiple

However just after the queue was stopped, an in-flight\nibmvnic_complete_tx() could have restarted the queue even as the reset is\nprogressing.\n\nSince the queue was restarted we could get a call to ibmvnic_xmit() which\ncan then access the bad tx_scrq (or other fields).\n\nWe cannot however simply have ibmvnic_complete_tx() check the -\u003eresetting\nbit and skip starting the queue. This can race at the \"back-end\" of a good\nreset which just restarted the queue but has not cleared the -\u003eresetting\nbit yet. If we skip restarting the queue due to -\u003eresetting being true,\nthe queue would remain stopped indefinitely potentially leading to transmit\ntimeouts.\n\nIOW -\u003eresetting is too broad for this purpose. Instead use a new flag\nthat indicates whether or not the queues are active. Only the open/\nreset paths control when the queues are active. ibmvnic_complete_tx()\nand others wake up the queue only if the queue is marked active.\n\nSo we will have:\n\tA. reset/open thread in ibmvnic_cleanup() and __ibmvnic_open()\n\n\t\t-\u003eresetting = true\n\t\t-\u003etx_queues_active = false\n\t\tdisable tx queues\n\t\t...\n\t\t-\u003etx_queues_active = true\n\t\tstart tx queues\n\n\tB. Tx interrupt in ibmvnic_complete_tx():\n\n\t\tif (-\u003etx_queues_active)\n\t\t\tnetif_wake_subqueue();\n\nTo ensure that -\u003etx_queues_active and state of the queues are consistent,\nwe need a lock which:\n\n\t- must also be taken in the interrupt path (ibmvnic_complete_tx())\n\t- shared across the multiple\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: mxs: Fix error handling in mxs_sgtl5000_probe
This function only calls of_node_put() in the regular path.
And it will cause refcount leak in error paths.
For example, when codec_np is NULL, saif_np[0] and saif_np[1]
are not NULL, it will cause leaks.
of_node_put() will check if the node pointer is NULL, so we can
call it directly to release the refcount of regular pointers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: usbip: fix a refcount leak in stub_probe()
usb_get_dev() is called in stub_device_alloc(). When stub_probe() fails
after that, usb_put_dev() needs to be called to release the reference.
Fix this by moving usb_put_dev() to sdev_free error path handling.
Find this by code review.

Summary
In the Linux kernel, the following vulnerability has been resolved:
video: fbdev: vesafb: Fix a use-after-free due early fb_info cleanup
Commit b3c9a924aab6 ("fbdev: vesafb: Cleanup fb_info in .fb_destroy rather
than .remove") fixed a use-after-free error due the vesafb driver freeing
the fb_info in the .remove handler instead of doing it in .fb_destroy.
This can happen if the .fb_destroy callback is executed after the .remove
callback, since the former tries to access a pointer freed by the latter.
But that change didn't take into account that another possible scenario is
that .fb_destroy is called before the .remove callback. For example, if no
process has the fbdev chardev opened by the time the driver is removed.
If that's the case, fb_info will be freed when unregister_framebuffer() is
called, making the fb_info pointer accessed in vesafb_remove() after that
to no longer be valid.
To prevent that, move the expression containing the info->par to happen
before the unregister_framebuffer() function call.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix bug_on ext4_mb_use_inode_pa
Hulk Robot reported a BUG_ON:
==================================================================
kernel BUG at fs/ext4/mballoc.c:3211!
[...]
RIP: 0010:ext4_mb_mark_diskspace_used.cold+0x85/0x136f

==================================================================
Above issue may happen as follows:
-------------------------------------
do_fsync
vfs_fsync_range
ext4_sync_file
file_write_and_wait_range
__filemap_fdatawrite_range
do_writepages
ext4_writepages
mpage_map_and_submit_extent
mpage_map_one_extent
ext4_map_blocks
ext4_mb_new_blocks
ext4_mb_normalize_request
>>> start + size <= ac->ac_o_ex.fe_logical
ext4_mb_regular_allocator
ext4_mb_simple_scan_group
ext4_mb_use_best_found
ext4_mb_new_preallocation
ext4_mb_new_inode_pa
ext4_mb_use_inode_pa
>>> set ac->ac_b_ex.fe_len <= 0
ext4_mb_mark_diskspace_used
>>> BUG_ON(ac->ac_b_ex.fe_len <= 0);
we can easily reproduce this problem with the following commands:
`fallocate -l100M disk`
`mkfs.ext4 -b 1024 -g 256 disk`
`mount disk /mnt`
`fsstress -d /mnt -l 0 -n 1000 -p 1`
The size must be smaller than or equal to EXT4_BLOCKS_PER_GROUP.
Therefore, "start + size <= ac->ac_o_ex.fe_logical" may occur
when the size is truncated. So start should be the start position of
the group where ac_o_ex.fe_logical is located after alignment.
In addition, when the value of fe_logical or EXT4_BLOCKS_PER_GROUP
is very large, the value calculated by start_off is more accurate.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ixgbe: Add locking to prevent panic when setting sriov_numvfs to zero
It is possible to disable VFs while the PF driver is processing requests
from the VF driver. This can result in a panic.

sleep 1
echo 0 > /sys/class/net/<devname>/device/sriov_numvfs
sleep 1
done
Add lock when disabling SR-IOV to prevent process VF mailbox communication.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: netem: account for backlog updates from child qdisc
In general, 'qlen' of any classful qdisc should keep track of the
number of packets that the qdisc itself and all of its children holds.
In case of netem, 'qlen' only accounts for the packets in its internal
tfifo. When netem is used with a child qdisc, the child qdisc can use
'qdisc_tree_reduce_backlog' to inform its parent, netem, about created
or dropped SKBs. This function updates 'qlen' and the backlog statistics
of netem, but netem does not account for changes made by a child qdisc.
'qlen' then indicates the wrong number of packets in the tfifo.
If a child qdisc creates new SKBs during enqueue and informs its parent
about this, netem's 'qlen' value is increased. When netem dequeues the
newly created SKBs from the child, the 'qlen' in netem is not updated.
If 'qlen' reaches the configured sch->limit, the enqueue function stops
working, even though the tfifo is not full.
Reproduce the bug:
Ensure that the sender machine has GSO enabled. Configure netem as root
qdisc and tbf as its child on the outgoing interface of the machine
as follows:
$ tc qdisc add dev <oif> root handle 1: netem delay 100ms limit 100
$ tc qdisc add dev <oif> parent 1:0 tbf rate 50Mbit burst 1542 latency 50ms
Send bulk TCP traffic out via this interface, e.g., by running an iPerf3
client on the machine. Check the qdisc statistics:
$ tc -s qdisc show dev <oif>
Statistics after 10s of iPerf3 TCP test before the fix (note that
netem's backlog > limit, netem stopped accepting packets):
qdisc netem 1: root refcnt 2 limit 1000 delay 100ms
Sent 2767766 bytes 1848 pkt (dropped 652, overlimits 0 requeues 0)
backlog 4294528236b 1155p requeues 0
qdisc tbf 10: parent 1:1 rate 50Mbit burst 1537b lat 50ms
Sent 2767766 bytes 1848 pkt (dropped 327, overlimits 7601 requeues 0)
backlog 0b 0p requeues 0
Statistics after the fix:
qdisc netem 1: root refcnt 2 limit 1000 delay 100ms
Sent 37766372 bytes 24974 pkt (dropped 9, overlimits 0 requeues 0)
backlog 0b 0p requeues 0
qdisc tbf 10: parent 1:1 rate 50Mbit burst 1537b lat 50ms
Sent 37766372 bytes 24974 pkt (dropped 327, overlimits 96017 requeues 0)
backlog 0b 0p requeues 0
tbf segments the GSO SKBs (tbf_segment) and updates the netem's 'qlen'.
The interface fully stops transferring packets and "locks". In this case,
the child qdisc and tfifo are empty, but 'qlen' indicates the tfifo is at
its limit and no more packets are accepted.
This patch adds a counter for the entries in the tfifo. Netem's 'qlen' is
only decreased when a packet is returned by its dequeue function, and not
during enqueuing into the child qdisc. External updates to 'qlen' are thus
accounted for and only the behavior of the backlog statistics changes. As
in other qdiscs, 'qlen' then keeps track of how many packets are held in
netem and all of its children. As before, sch->limit remains as the
maximum number of packets in the tfifo. The same applies to netem's
backlog statistics.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_payload: incorrect arithmetics when fetching VLAN header bits
If the offset + length goes over the ethernet + vlan header, then the
length is adjusted to copy the bytes that are within the boundaries of
the vlan_ethhdr scratchpad area. The remaining bytes beyond ethernet +
vlan header are copied directly from the skbuff data area.
Fix incorrect arithmetic operator: subtract, not add, the size of the
vlan header in case of double-tagged packets to adjust the length
accordingly to address CVE-2023-0179.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Fix memleak in tcp_bpf_sendmsg while sk msg is full
If tcp_bpf_sendmsg() is running while sk msg is full. When sk_msg_alloc()
returns -ENOMEM error, tcp_bpf_sendmsg() goes to wait_for_memory. If partial
memory has been alloced by sk_msg_alloc(), that is, msg_tx->sg.size is
greater than osize after sk_msg_alloc(), memleak occurs. To fix we use
sk_msg_trim() to release the allocated memory, then goto wait for memory.
Other call paths of sk_msg_alloc() have the similar issue, such as
tls_sw_sendmsg(), so handle sk_msg_trim logic inside sk_msg_alloc(),
as Cong Wang suggested.
This issue can cause the following info:

Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio_net: fix xdp_rxq_info bug after suspend/resume
The following sequence currently causes a driver bug warning
when using virtio_net:
# ip link set eth0 up
# echo mem > /sys/power/state (or e.g. # rtcwake -s 10 -m mem)
<resume>
# ip link set eth0 down
Missing register, driver bug
WARNING: CPU: 0 PID: 375 at net/core/xdp.c:138 xdp_rxq_info_unreg+0x58/0x60
Call trace:
xdp_rxq_info_unreg+0x58/0x60
virtnet_close+0x58/0xac
__dev_close_many+0xac/0x140
__dev_change_flags+0xd8/0x210
dev_change_flags+0x24/0x64
do_setlink+0x230/0xdd0
...
This happens because virtnet_freeze() frees the receive_queue
completely (including struct xdp_rxq_info) but does not call
xdp_rxq_info_unreg(). Similarly, virtnet_restore() sets up the
receive_queue again but does not call xdp_rxq_info_reg().
Actually, parts of virtnet_freeze_down() and virtnet_restore_up()
are almost identical to virtnet_close() and virtnet_open(): only
the calls to xdp_rxq_info_(un)reg() are missing. This means that
we can fix this easily and avoid such problems in the future by
just calling virtnet_close()/open() from the freeze/restore handlers.
Aside from adding the missing xdp_rxq_info calls the only difference
is that the refill work is only cancelled if netif_running(). However,
this should not make any functional difference since the refill work
should only be active if the network interface is actually up.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ethtool: do not perform operations on net devices being unregistered
There is a short period between a net device starts to be unregistered
and when it is actually gone. In that time frame ethtool operations
could still be performed, which might end up in unwanted or undefined
behaviours[1].
Do not allow ethtool operations after a net device starts its
unregistration. This patch targets the netlink part as the ioctl one
isn't affected: the reference to the net device is taken and the
operation is executed within an rtnl lock section and the net device
won't be found after unregister.
[1] For example adding Tx queues after unregister ends up in NULL
pointer exceptions and UaFs, such as:

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: ti: am65-cpsw-nuss: Fix some refcount leaks
of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
am65_cpsw_init_cpts() and am65_cpsw_nuss_probe() don't release
the refcount in error case.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/irdma: Fix sleep from invalid context BUG
Taking the qos_mutex to process RoCEv2 QP's on netdev events causes a
kernel splat.
Fix this by removing the handling for RoCEv2 in
irdma_cm_teardown_connections that uses the mutex. This handling is only
needed for iWARP to avoid having connections established while the link is
down or having connections remain functional after the IP address is
removed.
BUG: sleeping function called from invalid context at kernel/locking/mutex.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/rtas: Keep MSR[RI] set when calling RTAS
RTAS runs in real mode (MSR[DR] and MSR[IR] unset) and in 32-bit big
endian mode (MSR[SF,LE] unset).
The change in MSR is done in enter_rtas() in a relatively complex way,
since the MSR value could be hardcoded.
Furthermore, a panic has been reported when hitting the watchdog interrupt
while running in RTAS, this leads to the following stack trace:
watchdog: CPU 24 Hard LOCKUP
watchdog: CPU 24 TB:997512652051031, last heartbeat TB:997504470175378 (15980ms ago)

This happens because MSR[RI] is unset when entering RTAS but there is no
valid reason to not set it here.
RTAS is expected to be called with MSR[RI] as specified in PAPR+ section
"7.2.1 Machine State":
R1–7.2.1–9. If called with MSR[RI] equal to 1, then RTAS must protect
its own critical regions from recursion by setting the MSR[RI] bit to
0 when in the critical regions.
Fixing this by reviewing the way MSR is compute before calling RTAS. Now a
hardcoded value meaning real

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/xive/spapr: correct bitmap allocation size
kasan detects access beyond the end of the xibm->bitmap allocation:
BUG: KASAN: slab-out-of-bounds in _find_first_zero_bit+0x40/0x140

The buggy address belongs to the object at c00000001d1d0118
which belongs to the cache kmalloc-8 of size 8
The buggy address is located 0 bytes inside of
8-byte region [c00000001d1d0118, c00000001d1d0120)
The buggy address belongs to the physical page:
page:c00c000000074740 refcount:1 mapcount:0 mapping:0000000000000000 index:0xc00000001d1d0558 pfn:0x1d1d

raw: c00000001d1d0558 0000000001e1000a 00000001ffffffff 0000000000000000
page dumped because: kasan: bad access detected
Memory state around the buggy address:
c00000001d1d0000: fc 00 fc fc fc fc fc fc fc fc fc fc fc fc fc fc
c00000001d1d0080: fc fc 00 fc fc fc fc fc fc fc fc fc fc fc fc fc
>c00000001d1d0100: fc fc fc 02 fc fc fc fc fc fc fc fc fc fc fc fc
^
c00000001d1d0180: fc fc fc fc 04 fc fc fc fc fc fc fc fc fc fc fc
c00000001d1d0200: fc fc fc fc fc 04 fc fc fc fc fc fc fc fc fc fc
This happens because the allocation uses the wrong unit (bits) when it
should pass (BITS_TO_LONGS(count) * sizeof(long)) or equivalent. With small
numbers of bits, the allocated object can be smaller than sizeof(long),
which results in invalid accesses.
Use bitmap_zalloc() to allocate and initialize the irq bitmap, paired with
bitmap_free() for consistency.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/mdp5: Return error code in mdp5_mixer_release when deadlock is detected
There is a possibility for mdp5_get_global_state to return
-EDEADLK when acquiring the modeset lock, but currently global_state in
mdp5_mixer_release doesn't check for if an error is returned.
To avoid a NULL dereference error, let's have mdp5_mixer_release
check if an error is returned and propagate that error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sfc: fix use after free when disabling sriov
Use after free is detected by kfence when disabling sriov. What was read
after being freed was vf->pci_dev: it was freed from pci_disable_sriov
and later read in efx_ef10_sriov_free_vf_vports, called from
efx_ef10_sriov_free_vf_vswitching.
Set the pointer to NULL at release time to not trying to read it later.
Reproducer and dmesg log (note that kfence doesn't detect it every time):
$ echo 1 > /sys/class/net/enp65s0f0np0/device/sriov_numvfs
$ echo 0 > /sys/class/net/enp65s0f0np0/device/sriov_numvfs

Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: During unmount, ensure all cached dir instances drop their dentry
The unmount process (cifs_kill_sb() calling close_all_cached_dirs()) can
race with various cached directory operations, which ultimately results
in dentries not being dropped and these kernel BUGs:
BUG: Dentry ffff88814f37e358{i=1000000000080,n=/} still in use (2) [unmount of cifs cifs]
VFS: Busy inodes after unmount of cifs (cifs)
------------[ cut here ]------------
kernel BUG at fs/super.c:661!
This happens when a cfid is in the process of being cleaned up when, and
has been removed from the cfids->entries list, including:
- Receiving a lease break from the server
- Server reconnection triggers invalidate_all_cached_dirs(), which
removes all the cfids from the list
- The laundromat thread decides to expire an old cfid.
To solve these problems, dropping the dentry is done in queued work done
in a newly-added cfid_put_wq workqueue, and close_all_cached_dirs()
flushes that workqueue after it drops all the dentries of which it's
aware. This is a global workqueue (rather than scoped to a mount), but
the queued work is minimal.
The final cleanup work for cleaning up a cfid is performed via work
queued in the serverclose_wq workqueue; this is done separate from
dropping the dentries so that close_all_cached_dirs() doesn't block on
any server operations.
Both of these queued works expect to invoked with a cfid reference and
a tcon reference to avoid those objects from being freed while the work
is ongoing.
While we're here, add proper locking to close_all_cached_dirs(), and
locking around the freeing of cfid->dentry.

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-iolatency: Fix inflight count imbalances and IO hangs on offline
iolatency needs to track the number of inflight IOs per cgroup. As this
tracking can be expensive, it is disabled when no cgroup has iolatency
configured for the device. To ensure that the inflight counters stay
balanced, iolatency_set_limit() freezes the request_queue while manipulating
the enabled counter, which ensures that no IO is in flight and thus all
counters are zero.
Unfortunately, iolatency_set_limit() isn't the only place where the enabled
counter is manipulated. iolatency_pd_offline() can also dec the counter and
trigger disabling. As this disabling happens without freezing the q, this
can easily happen while some IOs are in flight and thus leak the counts.
This can be easily demonstrated by turning on iolatency on an one empty
cgroup while IOs are in flight in other cgroups and then removing the
cgroup. Note that iolatency shouldn't have been enabled elsewhere in the
system to ensure that removing the cgroup disables iolatency for the whole
device.
The following keeps flipping on and off iolatency on sda:
echo +io > /sys/fs/cgroup/cgroup.subtree_control
while true; do
mkdir -p /sys/fs/cgroup/test
echo '8:0 target=100000' > /sys/fs/cgroup/test/io.latency
sleep 1
rmdir /sys/fs/cgroup/test
sleep 1
done
and there's concurrent fio generating direct rand reads:
fio --name test --filename=/dev/sda --direct=1 --rw=randread \
--runtime=600 --time_based --iodepth=256 --numjobs=4 --bs=4k
while monitoring with the following drgn script:
while True:
for css in css_for_each_descendant_pre(prog['blkcg_root'].css.address_of_()):
for pos in hlist_for_each(container_of(css, 'struct blkcg', 'css').blkg_list):
blkg = container_of(pos, 'struct blkcg_gq', 'blkcg_node')
pd = blkg.pd[prog['blkcg_policy_iolatency'].plid]
if pd.value_() == 0:
continue
iolat = container_of(pd, 'struct iolatency_grp', 'pd')
inflight = iolat.rq_wait.inflight.counter.value_()
if inflight:
print(f'inflight={inflight} {disk_name(blkg.q.disk).decode("utf-8")} '
f'{cgroup_path(css.cgroup).decode("utf-8")}')
time.sleep(1)
The monitoring output looks like the following:
inflight=1 sda /user.slice
inflight=1 sda /user.slice
...
inflight=14 sda /user.slice
inflight=13 sda /user.slice
inflight=17 sda /user.slice
inflight=15 sda /user.slice
inflight=18 sda /user.slice
inflight=17 sda /user.slice
inflight=20 sda /user.slice
inflight=19 sda /user.slice <- fio stopped, inflight stuck at 19
inflight=19 sda /user.slice
inflight=19 sda /user.slice
If a cgroup with stuck inflight ends up getting throttled, the throttled IOs
will never get issued as there's no completion event to wake it up leading
to an indefinite hang.
This patch fixes the bug by unifying enable handling into a work item which
is automatically kicked off from iolatency_set_min_lat_nsec() which is
called from both iolatency_set_limit() and iolatency_pd_offline() paths.
Punting to a work item is necessary as iolatency_pd_offline() is called
under spinlocks while freezing a request_queue requires a sleepable context.
This also simplifies the code reducing LOC sans the comments and avoids the
unnecessary freezes which were happening whenever a cgroup's latency target
is newly set or cleared.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nblk-iolatency: Fix inflight count imbalances and IO hangs on offline\n\niolatency needs to track the number of inflight IOs per cgroup. As this\ntracking can be expensive, it is disabled when no cgroup has iolatency\nconfigured for the device. To ensure that the inflight counters stay\nbalanced, iolatency_set_limit() freezes the request_queue while manipulating\nthe enabled counter, which ensures that no IO is in flight and thus all\ncounters are zero.\n\nUnfortunately, iolatency_set_limit() isn\u0027t the only place where the enabled\ncounter is manipulated. iolatency_pd_offline() can also dec the counter and\ntrigger disabling. As this disabling happens without freezing the q, this\ncan easily happen while some IOs are in flight and thus leak the counts.\n\nThis can be easily demonstrated by turning on iolatency on an one empty\ncgroup while IOs are in flight in other cgroups and then removing the\ncgroup. Note that iolatency shouldn\u0027t have been enabled elsewhere in the\nsystem to ensure that removing the cgroup disables iolatency for the whole\ndevice.\n\nThe following keeps flipping on and off iolatency on sda:\n\n echo +io \u003e /sys/fs/cgroup/cgroup.subtree_control\n while true; do\n mkdir -p /sys/fs/cgroup/test\n echo \u00278:0 target=100000\u0027 \u003e /sys/fs/cgroup/test/io.latency\n sleep 1\n rmdir /sys/fs/cgroup/test\n sleep 1\n done\n\nand there\u0027s concurrent fio generating direct rand reads:\n\n fio --name test --filename=/dev/sda --direct=1 --rw=randread \\\n --runtime=600 --time_based --iodepth=256 --numjobs=4 --bs=4k\n\nwhile monitoring with the following drgn script:\n\n while True:\n for css in css_for_each_descendant_pre(prog[\u0027blkcg_root\u0027].css.address_of_()):\n for pos in hlist_for_each(container_of(css, \u0027struct blkcg\u0027, \u0027css\u0027).blkg_list):\n blkg = container_of(pos, \u0027struct blkcg_gq\u0027, \u0027blkcg_node\u0027)\n pd = blkg.pd[prog[\u0027blkcg_policy_iolatency\u0027].plid]\n if pd.value_() == 0:\n continue\n iolat = container_of(pd, \u0027struct iolatency_grp\u0027, \u0027pd\u0027)\n inflight = iolat.rq_wait.inflight.counter.value_()\n if inflight:\n print(f\u0027inflight={inflight} {disk_name(blkg.q.disk).decode(\"utf-8\")} \u0027\n f\u0027{cgroup_path(css.cgroup).decode(\"utf-8\")}\u0027)\n time.sleep(1)\n\nThe monitoring output looks like the following:\n\n inflight=1 sda /user.slice\n inflight=1 sda /user.slice\n ...\n inflight=14 sda /user.slice\n inflight=13 sda /user.slice\n inflight=17 sda /user.slice\n inflight=15 sda /user.slice\n inflight=18 sda /user.slice\n inflight=17 sda /user.slice\n inflight=20 sda /user.slice\n inflight=19 sda /user.slice \u003c- fio stopped, inflight stuck at 19\n inflight=19 sda /user.slice\n inflight=19 sda /user.slice\n\nIf a cgroup with stuck inflight ends up getting throttled, the throttled IOs\nwill never get issued as there\u0027s no completion event to wake it up leading\nto an indefinite hang.\n\nThis patch fixes the bug by unifying enable handling into a work item which\nis automatically kicked off from iolatency_set_min_lat_nsec() which is\ncalled from both iolatency_set_limit() and iolatency_pd_offline() paths.\nPunting to a work item is necessary as iolatency_pd_offline() is called\nunder spinlocks while freezing a request_queue requires a sleepable context.\n\nThis also simplifies the code reducing LOC sans the comments and avoids the\nunnecessary freezes which were happening whenever a cgroup\u0027s latency target\nis newly set or cleared."

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: hi311x: hi3110_can_ist(): fix potential use-after-free
The commit a22bd630cfff ("can: hi311x: do not report txerr and rxerr
during bus-off") removed the reporting of rxerr and txerr even in case
of correct operation (i. e. not bus-off).
The error count information added to the CAN frame after netif_rx() is
a potential use after free, since there is no guarantee that the skb
is in the same state. It might be freed or reused.
Fix the issue by postponing the netif_rx() call in case of txerr and
rxerr reporting.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: Intel: sof_sdw: handle errors on card registration
If the card registration fails, typically because of deferred probes,
the device properties added for headset codecs are not removed, which
leads to kernel oopses in driver bind/unbind tests.
We already clean-up the device properties when the card is removed,
this code can be moved as a helper and called upon card registration
errors.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: usb: rtl8150: enable basic endpoint checking
Syzkaller reports [1] encountering a common issue of utilizing a wrong
usb endpoint type during URB submitting stage. This, in turn, triggers
a warning shown below.
For now, enable simple endpoint checking (specifically, bulk and
interrupt eps, testing control one is not essential) to mitigate
the issue with a view to do other related cosmetic changes later,
if they are necessary.
[1] Syzkaller report:

Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: gpio-keys - cancel delayed work only in case of GPIO
gpio_keys module can either accept gpios or interrupts. The module
initializes delayed work in case of gpios only and is only used if
debounce timer is not used, so make sure cancel_delayed_work_sync()
is called only when its gpio-backed and debounce_use_hrtimer is false.
This fixes the issue seen below when the gpio_keys module is unloaded and
an interrupt pin is used instead of GPIO:

Summary
In the Linux kernel, the following vulnerability has been resolved:
video: fbdev: cirrusfb: check pixclock to avoid divide by zero
Do a sanity check on pixclock value to avoid divide by zero.
If the pixclock value is zero, the cirrusfb driver will round up
pixclock to get the derived frequency as close to maxclock as
possible.
Syzkaller reported a divide error in cirrusfb_check_pixclock.

When partialDecoding, it is EOF if we've either filled the output buffer
or can't proceed with reading an offset for following match.
In some extreme corner cases when compressed data is suitably corrupted,
UAF will occur. As reported by KASAN [1], LZ4_decompress_safe_partial
may lead to read out of bound problem during decoding. lz4 upstream has
fixed it [2] and this issue has been disscussed here [3] before.
current decompression routine was ported from lz4 v1.8.3, bumping
lib/lz4 to v1.9.+ is certainly a huge work to be done later, so, we'd
better fix it first.

Summary
In the Linux kernel, the following vulnerability has been resolved:
trace_events_hist: add check for return value of 'create_hist_field'
Function 'create_hist_field' is called recursively at
trace_events_hist.c:1954 and can return NULL-value that's why we have
to check it to avoid null pointer dereference.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

On a machine with the LBR format LBR_FORMAT_EIP_FLAGS2, when the TSX is

The lbr_from_signext_quirk_needed() is introduced to determine whether
the TSX quirk should be applied. However, the
lbr_from_signext_quirk_needed() is invoked before the
intel_pmu_lbr_init(), which parses the LBR format information. Without
the correct LBR format information, the TSX quirk never be applied.
Move the lbr_from_signext_quirk_needed() into the intel_pmu_lbr_init().
Checking x86_pmu.lbr_has_tsx in the lbr_from_signext_quirk_needed() is
not required anymore.
Both LBR_FORMAT_EIP_FLAGS2 and LBR_FORMAT_INFO have LBR_TSX flag, but
only the LBR_FORMAT_EIP_FLAGS2 requirs the quirk. Update the comments
accordingly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Squashfs: fix handling and sanity checking of xattr_ids count
A Sysbot [1] corrupted filesystem exposes two flaws in the handling and
sanity checking of the xattr_ids count in the filesystem. Both of these
flaws cause computation overflow due to incorrect typing.
In the corrupted filesystem the xattr_ids value is 4294967071, which
stored in a signed variable becomes the negative number -225.
Flaw 1 (64-bit systems only):
The signed integer xattr_ids variable causes sign extension.
This causes variable overflow in the SQUASHFS_XATTR_*(A) macros. The
variable is first multiplied by sizeof(struct squashfs_xattr_id) where the
type of the sizeof operator is "unsigned long".
On a 64-bit system this is 64-bits in size, and causes the negative number
to be sign extended and widened to 64-bits and then become unsigned. This
produces the very large number 18446744073709548016 or 2^64 - 3600. This
number when rounded up by SQUASHFS_METADATA_SIZE - 1 (8191 bytes) and
divided by SQUASHFS_METADATA_SIZE overflows and produces a length of 0
(stored in len).
Flaw 2 (32-bit systems only):
On a 32-bit system the integer variable is not widened by the unsigned
long type of the sizeof operator (32-bits), and the signedness of the
variable has no effect due it always being treated as unsigned.
The above corrupted xattr_ids value of 4294967071, when multiplied
overflows and produces the number 4294963696 or 2^32 - 3400. This number
when rounded up by SQUASHFS_METADATA_SIZE - 1 (8191 bytes) and divided by
SQUASHFS_METADATA_SIZE overflows again and produces a length of 0.
The effect of the 0 length computation:
In conjunction with the corrupted xattr_ids field, the filesystem also has
a corrupted xattr_table_start value, where it matches the end of
filesystem value of 850.
This causes the following sanity check code to fail because the
incorrectly computed len of 0 matches the incorrect size of the table
reported by the superblock (0 bytes).
len = SQUASHFS_XATTR_BLOCK_BYTES(*xattr_ids);
indexes = SQUASHFS_XATTR_BLOCKS(*xattr_ids);
/*
* The computed size of the index table (len bytes) should exactly
* match the table start and end points
*/
start = table_start + sizeof(*id_table);
end = msblk->bytes_used;
if (len != (end - start))
return ERR_PTR(-EINVAL);
Changing the xattr_ids variable to be "usigned int" fixes the flaw on a
64-bit system. This relies on the fact the computation is widened by the
unsigned long type of the sizeof operator.
Casting the variable to u64 in the above macro fixes this flaw on a 32-bit
system.
It also means 64-bit systems do not implicitly rely on the type of the
sizeof operator to widen the computation.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nSquashfs: fix handling and sanity checking of xattr_ids count\n\nA Sysbot [1] corrupted filesystem exposes two flaws in the handling and\nsanity checking of the xattr_ids count in the filesystem. Both of these\nflaws cause computation overflow due to incorrect typing.\n\nIn the corrupted filesystem the xattr_ids value is 4294967071, which\nstored in a signed variable becomes the negative number -225.\n\nFlaw 1 (64-bit systems only):\n\nThe signed integer xattr_ids variable causes sign extension.\n\nThis causes variable overflow in the SQUASHFS_XATTR_*(A) macros. The\nvariable is first multiplied by sizeof(struct squashfs_xattr_id) where the\ntype of the sizeof operator is \"unsigned long\".\n\nOn a 64-bit system this is 64-bits in size, and causes the negative number\nto be sign extended and widened to 64-bits and then become unsigned. This\nproduces the very large number 18446744073709548016 or 2^64 - 3600. This\nnumber when rounded up by SQUASHFS_METADATA_SIZE - 1 (8191 bytes) and\ndivided by SQUASHFS_METADATA_SIZE overflows and produces a length of 0\n(stored in len).\n\nFlaw 2 (32-bit systems only):\n\nOn a 32-bit system the integer variable is not widened by the unsigned\nlong type of the sizeof operator (32-bits), and the signedness of the\nvariable has no effect due it always being treated as unsigned.\n\nThe above corrupted xattr_ids value of 4294967071, when multiplied\noverflows and produces the number 4294963696 or 2^32 - 3400. This number\nwhen rounded up by SQUASHFS_METADATA_SIZE - 1 (8191 bytes) and divided by\nSQUASHFS_METADATA_SIZE overflows again and produces a length of 0.\n\nThe effect of the 0 length computation:\n\nIn conjunction with the corrupted xattr_ids field, the filesystem also has\na corrupted xattr_table_start value, where it matches the end of\nfilesystem value of 850.\n\nThis causes the following sanity check code to fail because the\nincorrectly computed len of 0 matches the incorrect size of the table\nreported by the superblock (0 bytes).\n\n len = SQUASHFS_XATTR_BLOCK_BYTES(*xattr_ids);\n indexes = SQUASHFS_XATTR_BLOCKS(*xattr_ids);\n\n /*\n * The computed size of the index table (len bytes) should exactly\n * match the table start and end points\n */\n start = table_start + sizeof(*id_table);\n end = msblk-\u003ebytes_used;\n\n if (len != (end - start))\n return ERR_PTR(-EINVAL);\n\nChanging the xattr_ids variable to be \"usigned int\" fixes the flaw on a\n64-bit system. This relies on the fact the computation is widened by the\nunsigned long type of the sizeof operator.\n\nCasting the variable to u64 in the above macro fixes this flaw on a 32-bit\nsystem.\n\nIt also means 64-bit systems do not implicitly rely on the type of the\nsizeof operator to widen the computation.\n\n[1] https://lore.kernel.org/lkml/000000000000cd44f005f1a0f17f@google.com/"

Summary
In the Linux kernel, the following vulnerability has been resolved:
team: prevent adding a device which is already a team device lower
Prevent adding a device which is already a team device lower,
e.g. adding veth0 if vlan1 was already added and veth0 is a lower of
vlan1.
This is not useful in practice and can lead to recursive locking:
$ ip link add veth0 type veth peer name veth1
$ ip link set veth0 up
$ ip link set veth1 up
$ ip link add link veth0 name veth0.1 type vlan protocol 802.1Q id 1
$ ip link add team0 type team
$ ip link set veth0.1 down
$ ip link set veth0.1 master team0
team0: Port device veth0.1 added
$ ip link set veth0 down
$ ip link set veth0 master team0

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: phy: dp83822: Fix null pointer access on DP83825/DP83826 devices
The probe() function is only used for the DP83822 PHY, leaving the
private data pointer uninitialized for the smaller DP83825/26 models.
While all uses of the private data structure are hidden in 82822 specific
callbacks, configuring the interrupt is shared across all models.
This causes a NULL pointer dereference on the smaller PHYs as it accesses
the private data unchecked. Verifying the pointer avoids that.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: Fix memory corruption in VF driver
Disable VF's RX/TX queues, when it's disabled. VF can have queues enabled,
when it requests a reset. If PF driver assumes that VF is disabled,
while VF still has queues configured, VF may unmap DMA resources.
In such scenario device still can map packets to memory, which ends up
silently corrupting it.
Previously, VF driver could experience memory corruption, which lead to
crash:

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: fix a NULL pointer dereference in nvme_alloc_admin_tags
In nvme_alloc_admin_tags, the admin_q can be set to an error (typically
-ENOMEM) if the blk_mq_init_queue call fails to set up the queue, which
is checked immediately after the call. However, when we return the error
message up the stack, to nvme_reset_work the error takes us to
nvme_remove_dead_ctrl()
nvme_dev_disable()
nvme_suspend_queue(&dev->queues[0]).
Here, we only check that the admin_q is non-NULL, rather than not
an error or NULL, and begin quiescing a queue that never existed, leading
to bad / NULL pointer dereference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
igc: Reinstate IGC_REMOVED logic and implement it properly
The initially merged version of the igc driver code (via commit
146740f9abc4, "igc: Add support for PF") contained the following
IGC_REMOVED checks in the igc_rd32/wr32() MMIO accessors:
u32 igc_rd32(struct igc_hw *hw, u32 reg)
{
u8 __iomem *hw_addr = READ_ONCE(hw->hw_addr);
u32 value = 0;
if (IGC_REMOVED(hw_addr))
return ~value;
value = readl(&hw_addr[reg]);
/* reads should not return all F's */
if (!(~value) && (!reg || !(~readl(hw_addr))))
hw->hw_addr = NULL;
return value;
}
And:
#define wr32(reg, val) \
do { \
u8 __iomem *hw_addr = READ_ONCE((hw)->hw_addr); \
if (!IGC_REMOVED(hw_addr)) \
writel((val), &hw_addr[(reg)]); \
} while (0)
E.g. igb has similar checks in its MMIO accessors, and has a similar
macro E1000_REMOVED, which is implemented as follows:
#define E1000_REMOVED(h) unlikely(!(h))
These checks serve to detect and take note of an 0xffffffff MMIO read
return from the device, which can be caused by a PCIe link flap or some
other kind of PCI bus error, and to avoid performing MMIO reads and
writes from that point onwards.
However, the IGC_REMOVED macro was not originally implemented:
#ifndef IGC_REMOVED
#define IGC_REMOVED(a) (0)
#endif /* IGC_REMOVED */
This led to the IGC_REMOVED logic to be removed entirely in a
subsequent commit (commit 3c215fb18e70, "igc: remove IGC_REMOVED
function"), with the rationale that such checks matter only for
virtualization and that igc does not support virtualization -- but a
PCIe device can become detached even without virtualization being in
use, and without proper checks, a PCIe bus error affecting an igc
adapter will lead to various NULL pointer dereferences, as the first
access after the error will set hw->hw_addr to NULL, and subsequent
accesses will blindly dereference this now-NULL pointer.
This patch reinstates the IGC_REMOVED checks in igc_rd32/wr32(), and
implements IGC_REMOVED the way it is done for igb, by checking for the
unlikely() case of hw_addr being NULL. This change prevents the oopses
seen when a PCIe link flap occurs on an igc adapter.

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: ftrace: consistently handle PLTs.
Sometimes it is necessary to use a PLT entry to call an ftrace
trampoline. This is handled by ftrace_make_call() and ftrace_make_nop(),
with each having *almost* identical logic, but this is not handled by
ftrace_modify_call() since its introduction in commit:
3b23e4991fb66f6d ("arm64: implement ftrace with regs")
Due to this, if we ever were to call ftrace_modify_call() for a callsite
which requires a PLT entry for a trampoline, then either:
a) If the old addr requires a trampoline, ftrace_modify_call() will use
an out-of-range address to generate the 'old' branch instruction.
This will result in warnings from aarch64_insn_gen_branch_imm() and
ftrace_modify_code(), and no instructions will be modified. As
ftrace_modify_call() will return an error, this will result in
subsequent internal ftrace errors.
b) If the old addr does not require a trampoline, but the new addr does,
ftrace_modify_call() will use an out-of-range address to generate the
'new' branch instruction. This will result in warnings from
aarch64_insn_gen_branch_imm(), and ftrace_modify_code() will replace
the 'old' branch with a BRK. This will result in a kernel panic when
this BRK is later executed.
Practically speaking, case (a) is vastly more likely than case (b), and
typically this will result in internal ftrace errors that don't
necessarily affect the rest of the system. This can be demonstrated with
an out-of-tree test module which triggers ftrace_modify_call(), e.g.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: openvswitch: fix leak of nested actions
While parsing user-provided actions, openvswitch module may dynamically
allocate memory and store pointers in the internal copy of the actions.
So this memory has to be freed while destroying the actions.
Currently there are only two such actions: ct() and set(). However,
there are many actions that can hold nested lists of actions and
ovs_nla_free_flow_actions() just jumps over them leaking the memory.
For example, removal of the flow with the following actions will lead
to a leak of the memory allocated by nf_ct_tmpl_alloc():
actions:clone(ct(commit),0)
Non-freed set() action may also leak the 'dst' structure for the
tunnel info including device references.
Under certain conditions with a high rate of flow rotation that may
cause significant memory leak problem (2MB per second in reporter's
case). The problem is also hard to mitigate, because the user doesn't
have direct control over the datapath flows generated by OVS.
Fix that by iterating over all the nested actions and freeing
everything that needs to be freed recursively.
New build time assertion should protect us from this problem if new
actions will be added in the future.
Unfortunately, openvswitch module doesn't use NLA_F_NESTED, so all
attributes has to be explicitly checked. sample() and clone() actions
are mixing extra attributes into the user-provided action list. That
prevents some code generalization too.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: always check VF VSI pointer values
The ice_get_vf_vsi function can return NULL in some cases, such as if
handling messages during a reset where the VSI is being removed and
recreated.
Several places throughout the driver do not bother to check whether this
VSI pointer is valid. Static analysis tools maybe report issues because
they detect paths where a potentially NULL pointer could be dereferenced.
Fix this by checking the return value of ice_get_vf_vsi everywhere.

Summary
In the Linux kernel, the following vulnerability has been resolved:
efi: fix potential NULL deref in efi_mem_reserve_persistent
When iterating on a linked list, a result of memremap is dereferenced
without checking it for NULL.
This patch adds a check that falls back on allocating a new page in
case memremap doesn't succeed.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
[ardb: return -ENOMEM instead of breaking out of the loop]

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Fix possible deadlock in rfcomm_sk_state_change
syzbot reports a possible deadlock in rfcomm_sk_state_change [1].
While rfcomm_sock_connect acquires the sk lock and waits for
the rfcomm lock, rfcomm_sock_release could have the rfcomm
lock and hit a deadlock for acquiring the sk lock.
Here's a simplified flow:
rfcomm_sock_connect:
lock_sock(sk)
rfcomm_dlc_open:
rfcomm_lock()
rfcomm_sock_release:
rfcomm_sock_shutdown:
rfcomm_lock()
__rfcomm_dlc_close:
rfcomm_k_state_change:
lock_sock(sk)
This patch drops the sk lock before calling rfcomm_dlc_open to
avoid the possible deadlock and holds sk's reference count to
prevent use-after-free after rfcomm_dlc_open completes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix call trace observed during I/O with CMF enabled
The following was seen with CMF enabled:
BUG: using smp_processor_id() in preemptible
code: systemd-udevd/31711
kernel: caller is lpfc_update_cmf_cmd+0x214/0x420 [lpfc]
kernel: CPU: 12 PID: 31711 Comm: systemd-udevd
kernel: Call Trace:
kernel: <TASK>
kernel: dump_stack_lvl+0x44/0x57
kernel: check_preemption_disabled+0xbf/0xe0
kernel: lpfc_update_cmf_cmd+0x214/0x420 [lpfc]
kernel: lpfc_nvme_fcp_io_submit+0x23b4/0x4df0 [lpfc]
this_cpu_ptr() calls smp_processor_id() in a preemptible context.
Fix by using per_cpu_ptr() with raw_smp_processor_id() instead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: iscsi_tcp: Fix UAF during login when accessing the shost ipaddress
If during iscsi_sw_tcp_session_create() iscsi_tcp_r2tpool_alloc() fails,
userspace could be accessing the host's ipaddress attr. If we then free the
session via iscsi_session_teardown() while userspace is still accessing the
session we will hit a use after free bug.
Set the tcp_sw_host->session after we have completed session creation and
can no longer fail.

Summary
In the Linux kernel, the following vulnerability has been resolved:
regulator: da9121: Fix uninit-value in da9121_assign_chip_model()
KASAN report slab-out-of-bounds in __regmap_init as follows:
BUG: KASAN: slab-out-of-bounds in __regmap_init drivers/base/regmap/regmap.c:841
Read of size 1 at addr ffff88803678cdf1 by task xrun/9137
CPU: 0 PID: 9137 Comm: xrun Tainted: G W 5.18.0-rc2
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.13.0-1ubuntu1.1 04/01/2014

This happend when da9121 device is probe by da9121_i2c_id, but with
invalid dts. Thus, chip->subvariant_id is set to -EINVAL, and later
da9121_assign_chip_model() will access 'regmap' without init it.
Fix it by return -EINVAL from da9121_assign_chip_model() if
'chip->subvariant_id' is invalid.

Summary
In the Linux kernel, the following vulnerability has been resolved:
watch_queue: Fix NULL dereference in error cleanup
In watch_queue_set_size(), the error cleanup code doesn't take account of
the fact that __free_page() can't handle a NULL pointer when trying to free
up buffer pages that did get allocated.
Fix this by only calling __free_page() on the pages actually allocated.
Without the fix, this can lead to something like the following:
BUG: KASAN: null-ptr-deref in __free_pages+0x1f/0x1b0 mm/page_alloc.c:5473
Read of size 4 at addr 0000000000000034 by task syz-executor168/3599

Summary
In the Linux kernel, the following vulnerability has been resolved:
list: fix a data-race around ep->rdllist
ep_poll() first calls ep_events_available() with no lock held and checks
if ep->rdllist is empty by list_empty_careful(), which reads
rdllist->prev. Thus all accesses to it need some protection to avoid
store/load-tearing.
Note INIT_LIST_HEAD_RCU() already has the annotation for both prev
and next.
Commit bf3b9f6372c4 ("epoll: Add busy poll support to epoll with socket
fds.") added the first lockless ep_events_available(), and commit
c5a282e9635e ("fs/epoll: reduce the scope of wq lock in epoll_wait()")
made some ep_events_available() calls lockless and added single call under
a lock, finally commit e59d3c64cba6 ("epoll: eliminate unnecessary lock
for zero timeout") made the last ep_events_available() lockless.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nbd: fix race between nbd_alloc_config() and module removal
When nbd module is being removing, nbd_alloc_config() may be
called concurrently by nbd_genl_connect(), although try_module_get()
will return false, but nbd_alloc_config() doesn't handle it.
The race may lead to the leak of nbd_config and its related
resources (e.g, recv_workq) and oops in nbd_read_stat() due
to the unload of nbd module as shown below:
BUG: kernel NULL pointer dereference, address: 0000000000000040
Oops: 0000 [#1] SMP PTI
CPU: 5 PID: 13840 Comm: kworker/u17:33 Not tainted 5.14.0+ #1
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996)
Workqueue: knbd16-recv recv_work [nbd]
RIP: 0010:nbd_read_stat.cold+0x130/0x1a4 [nbd]
Call Trace:
recv_work+0x3b/0xb0 [nbd]
process_one_work+0x1ed/0x390
worker_thread+0x4a/0x3d0
kthread+0x12a/0x150
ret_from_fork+0x22/0x30
Fixing it by checking the return value of try_module_get()
in nbd_alloc_config(). As nbd_alloc_config() may return ERR_PTR(-ENODEV),
assign nbd->config only when nbd_alloc_config() succeeds to ensure
the value of nbd->config is binary (valid or NULL).
Also adding a debug message to check the reference counter
of nbd_config during module removal.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/kexec: fix memory leak of elf header buffer
This is reported by kmemleak detector:
unreferenced object 0xffffc900002a9000 (size 4096):
comm "kexec", pid 14950, jiffies 4295110793 (age 373.951s)

In crash_prepare_elf64_headers(), a buffer is allocated via vmalloc() to
store elf headers. While it's not freed back to system correctly when
kdump kernel is reloaded or unloaded. Then memory leak is caused. Fix it
by introducing x86 specific function arch_kimage_file_post_load_cleanup(),
and freeing the buffer there.
And also remove the incorrect elf header buffer freeing code. Before
calling arch specific kexec_file loading function, the image instance has
been initialized. So 'image->elf_headers' must be NULL. It doesn't make
sense to free the elf header buffer in the place.
Three different people have reported three bugs about the memory leak on
x86_64 inside Redhat.

Summary
In the Linux kernel, the following vulnerability has been resolved:
VMCI: Use threaded irqs instead of tasklets
The vmci_dispatch_dgs() tasklet function calls vmci_read_data()
which uses wait_event() resulting in invalid sleep in an atomic
context (and therefore potentially in a deadlock).
Use threaded irqs to fix this issue and completely remove usage
of tasklets.

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: isotp: split tx timer into transmission and timeout
The timer for the transmission of isotp PDUs formerly had two functions:
1. send two consecutive frames with a given time gap
2. monitor the timeouts for flow control frames and the echo frames
This led to larger txstate checks and potentially to a problem discovered
by syzbot which enabled the panic_on_warn feature while testing.
The former 'txtimer' function is split into 'txfrtimer' and 'txtimer'
to handle the two above functionalities with separate timer callbacks.
The two simplified timers now run in one-shot mode and make the state
transitions (especially with isotp_rcv_echo) better understandable.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: stmmac: dwc-qos: Disable split header for Tegra194
There is a long-standing issue with the Synopsys DWC Ethernet driver
for Tegra194 where random system crashes have been observed [0]. The
problem occurs when the split header feature is enabled in the stmmac
driver. In the bad case, a larger than expected buffer length is
received and causes the calculation of the total buffer length to
overflow. This results in a very large buffer length that causes the
kernel to crash. Why this larger buffer length is received is not clear,
however, the feedback from the NVIDIA design team is that the split
header feature is not supported for Tegra194. Therefore, disable split
header support for Tegra194 to prevent these random crashes from
occurring.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: Fix call trace in setup_tx_descriptors
After PF reset and ethtool -t there was call trace in dmesg
sometimes leading to panic. When there was some time, around 5
seconds, between reset and test there were no errors.
Problem was that pf reset calls i40e_vsi_close in prep_for_reset
and ethtool -t calls i40e_vsi_close in diag_test. If there was not
enough time between those commands the second i40e_vsi_close starts
before previous i40e_vsi_close was done which leads to crash.
Add check to diag_test if pf is in reset and don't start offline
tests if it is true.
Add netif_info("testing failed") into unhappy path of i40e_diag_test()

Summary
In the Linux kernel, the following vulnerability has been resolved:
tap: add missing verification for short frame
The cited commit missed to check against the validity of the frame length
in the tap_get_user_xdp() path, which could cause a corrupted skb to be
sent downstack. Even before the skb is transmitted, the
tap_get_user_xdp()-->skb_set_network_header() may assume the size is more
than ETH_HLEN. Once transmitted, this could either cause out-of-bound
access beyond the actual length, or confuse the underlayer with incorrect
or inconsistent header length in the skb metadata.
In the alternative path, tap_get_user() already prohibits short frame which
has the length less than Ethernet header size from being transmitted.
This is to drop any frame shorter than the Ethernet header size just like
how tap_get_user() does.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Implement ref count for SRB
The timeout handler and the done function are racing. When
qla2x00_async_iocb_timeout() starts to run it can be preempted by the
normal response path (via the firmware?). qla24xx_async_gpsc_sp_done()
releases the SRB unconditionally. When scheduling back to
qla2x00_async_iocb_timeout() qla24xx_async_abort_cmd() will access an freed
sp->qpair pointer:
qla2xxx [0000:83:00.0]-2871:0: Async-gpsc timeout - hdl=63d portid=234500 50:06:0e:80:08:77:b6:21.

qla2xxx [0000:83:00.0]-28d8:0: qla24xx_handle_gpsc_event 50:06:0e:80:08:77:b6:21 DS 7 LS 6 rc 0 login 1|1 rscn 1|0 lid 5
BUG: unable to handle kernel NULL pointer dereference at 0000000000000004
IP: qla24xx_async_abort_cmd+0x1b/0x1c0 [qla2xxx]
Obvious solution to this is to introduce a reference counter. One reference
is taken for the normal code path (the 'good' case) and one for the timeout
path. As we always race between the normal good case and the timeout/abort
handler we need to serialize it. Also we cannot assume any order between
the handlers. Since this is slow path we can use proper synchronization via
locks.
When we are able to cancel a timer (del_timer returns 1) we know there
can't be any error handling in progress because the timeout handler hasn't
expired yet, thus we can safely decrement the refcounter by one.
If we are not able to cancel the timer, we know an abort handler is
running. We have to make sure we call sp->done() in the abort handlers
before calling kref_put().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ARM: exynos: Fix refcount leak in exynos_map_pmu
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
of_node_put() checks null pointer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ceph: fix possible deadlock when holding Fwb to get inline_data
1, mount with wsync.
2, create a file with O_RDWR, and the request was sent to mds.0:
ceph_atomic_open()-->
ceph_mdsc_do_request(openc)
finish_open(file, dentry, ceph_open)-->
ceph_open()-->
ceph_init_file()-->
ceph_init_file_info()-->
ceph_uninline_data()-->
{
...
if (inline_version == 1 || /* initial version, no data */
inline_version == CEPH_INLINE_NONE)
goto out_unlock;
...
}
The inline_version will be 1, which is the initial version for the
new create file. And here the ci->i_inline_version will keep with 1,
it's buggy.
3, buffer write to the file immediately:
ceph_write_iter()-->
ceph_get_caps(file, need=Fw, want=Fb, ...);
generic_perform_write()-->
a_ops->write_begin()-->
ceph_write_begin()-->
netfs_write_begin()-->
netfs_begin_read()-->
netfs_rreq_submit_slice()-->
netfs_read_from_server()-->
rreq->netfs_ops->issue_read()-->
ceph_netfs_issue_read()-->
{
...
if (ci->i_inline_version != CEPH_INLINE_NONE &&
ceph_netfs_issue_op_inline(subreq))
return;
...
}
ceph_put_cap_refs(ci, Fwb);
The ceph_netfs_issue_op_inline() will send a getattr(Fsr) request to
mds.1.
4, then the mds.1 will request the rd lock for CInode::filelock from
the auth mds.0, the mds.0 will do the CInode::filelock state transation
from excl --> sync, but it need to revoke the Fxwb caps back from the
clients.
While the kernel client has aleady held the Fwb caps and waiting for
the getattr(Fsr).
It's deadlock!

Summary
In the Linux kernel, the following vulnerability has been resolved:
vrf: use RCU protection in l3mdev_l3_out()
l3mdev_l3_out() can be called without RCU being held:
raw_sendmsg()
ip_push_pending_frames()
ip_send_skb()
ip_local_out()
__ip_local_out()
l3mdev_ip_out()
Add rcu_read_lock() / rcu_read_unlock() pair to avoid
a potential UAF.

Summary
In the Linux kernel, the following vulnerability has been resolved:
irqchip/realtek-rtl: Fix refcount leak in map_interrupts
of_find_node_by_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
This function doesn't call of_node_put() in error path.
Call of_node_put() directly after of_property_read_u32() to cover
both normal path and error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc2: Fix memory leak in dwc2_hcd_init
usb_create_hcd will alloc memory for hcd, and we should
call usb_put_hcd to free it when platform_get_resource()
fails to prevent memory leak.
goto error2 label instead error1 to fix this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: davinci: vpif: fix use-after-free on driver unbind
The driver allocates and registers two platform device structures during
probe, but the devices were never deregistered on driver unbind.
This results in a use-after-free on driver unbind as the device
structures were allocated using devres and would be freed by driver
core when remove() returns.
Fix this by adding the missing deregistration calls to the remove()
callback and failing probe on registration errors.
Note that the platform device structures must be freed using a proper
release callback to avoid leaking associated resources like device
names.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: fix queue selection for mesh/OCB interfaces
When using iTXQ, the code assumes that there is only one vif queue for
broadcast packets, using the BE queue. Allowing non-BE queue marking
violates that assumption and txq->ac == skb_queue_mapping is no longer
guaranteed. This can cause issues with queue handling in the driver and
also causes issues with the recent ATF change, resulting in an AQL
underflow warning.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cachefiles: unmark inode in use in error path
Unmark inode in use if error encountered. If the in-use flag leakage
occurs in cachefiles_open_file(), Cachefiles will complain "Inode
already in use" when later another cookie with the same index key is
looked up.
If the in-use flag leakage occurs in cachefiles_create_tmpfile(), though
the "Inode already in use" warning won't be triggered, fix the leakage
anyway.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: pcm: oss: Fix race at SNDCTL_DSP_SYNC
There is a small race window at snd_pcm_oss_sync() that is called from
OSS PCM SNDCTL_DSP_SYNC ioctl; namely the function calls
snd_pcm_oss_make_ready() at first, then takes the params_lock mutex
for the rest. When the stream is set up again by another thread
between them, it leads to inconsistency, and may result in unexpected
results such as NULL dereference of OSS buffer as a fuzzer spotted
recently.
The fix is simply to cover snd_pcm_oss_make_ready() call into the same
params_lock mutex with snd_pcm_oss_make_ready_locked() variant.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: mdio: validate parameter addr in mdiobus_get_phy()
The caller may pass any value as addr, what may result in an out-of-bounds
access to array mdio_map. One existing case is stmmac_init_phy() that
may pass -1 as addr. Therefore validate addr before using it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: rt5645: Fix errorenous cleanup order
There is a logic error when removing rt5645 device as the function
rt5645_i2c_remove() first cancel the &rt5645->jack_detect_work and
delete the &rt5645->btn_check_timer latter. However, since the timer
handler rt5645_btn_check_callback() will re-queue the jack_detect_work,
this cleanup order is buggy.
That is, once the del_timer_sync in rt5645_i2c_remove is concurrently
run with the rt5645_btn_check_callback, the canceled jack_detect_work
will be rescheduled again, leading to possible use-after-free.
This patch fix the issue by placing the del_timer_sync function before
the cancel_delayed_work_sync.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/MCE/AMD: Fix memory leak when threshold_create_bank() fails
In mce_threshold_create_device(), if threshold_create_bank() fails, the
previously allocated threshold banks array @bp will be leaked because
the call to mce_threshold_remove_device() will not free it.
This happens because mce_threshold_remove_device() fetches the pointer
through the threshold_banks per-CPU variable but bp is written there
only after the bank creation is successful, and not before, when
threshold_create_bank() fails.
Add a helper which unwinds all the bank creation work previously done
and pass into it the previously allocated threshold banks array for
freeing.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/v3d: Fix null pointer dereference of pointer perfmon
In the unlikely event that pointer perfmon is null the WARN_ON return path
occurs after the pointer has already been deferenced. Fix this by only
dereferencing perfmon after it has been null checked.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers: tty: serial: Fix deadlock in sa1100_set_termios()
There is a deadlock in sa1100_set_termios(), which is shown
below:
(Thread 1) | (Thread 2)
| sa1100_enable_ms()
sa1100_set_termios() | mod_timer()
spin_lock_irqsave() //(1) | (wait a time)
... | sa1100_timeout()
del_timer_sync() | spin_lock_irqsave() //(2)
(wait timer to stop) | ...
We hold sport->port.lock in position (1) of thread 1 and
use del_timer_sync() to wait timer to stop, but timer handler
also need sport->port.lock in position (2) of thread 2. As a result,
sa1100_set_termios() will block forever.
This patch moves del_timer_sync() before spin_lock_irqsave()
in order to prevent the deadlock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ip: Fix data-races around sysctl_ip_prot_sock.
sysctl_ip_prot_sock is accessed concurrently, and there is always a chance
of data-race. So, all readers and writers need some basic protection to
avoid load/store-tearing.

The issue here is that board file loading happens after ath11k_pci_probe()
succesfully returns (ath11k initialisation happends asynchronously) and the
suspend handler is still enabled, of course failing as ath11k is not properly
initialised. Fix this by checking ATH11K_FLAG_QMI_FAIL during both suspend and
resume.

dax: make sure inodes are flushed before destroy cache
A bug can be triggered by following command
$ modprobe nd_pmem && modprobe -r nd_pmem
[ 10.060014] BUG dax_cache (Not tainted): Objects remaining in dax_cache on __kmem_cache_shutdown()

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix null pointer dereference after failing to issue FLOGI and PLOGI
If lpfc_issue_els_flogi() fails and returns non-zero status, the node
reference count is decremented to trigger the release of the nodelist
structure. However, if there is a prior registration or dev-loss-evt work
pending, the node may be released prematurely. When dev-loss-evt
completes, the released node is referenced causing a use-after-free null
pointer dereference.
Similarly, when processing non-zero ELS PLOGI completion status in
lpfc_cmpl_els_plogi(), the ndlp flags are checked for a transport
registration before triggering node removal. If dev-loss-evt work is
pending, the node may be released prematurely and a subsequent call to
lpfc_dev_loss_tmo_handler() results in a use after free ndlp dereference.
Add test for pending dev-loss before decrementing the node reference count
for FLOGI, PLOGI, PRLI, and ADISC handling.

It may happen as follows:
1. write inline_data inode
vfs_write
new_sync_write
ext4_file_write_iter
ext4_buffered_write_iter
generic_perform_write
ext4_da_write_begin
ext4_da_write_inline_data_begin -> If inline data size too
small will allocate block to write, then mapping will has
dirty page
ext4_da_convert_inline_data_to_extent ->clear EXT4_STATE_MAY_INLINE_DATA
2. fallocate
do_vfs_ioctl
ioctl_preallocate
vfs_fallocate
ext4_fallocate
ext4_convert_inline_data
ext4_convert_inline_data_nolock
ext4_map_blocks -> fail will goto restore data
ext4_restore_inline_data
ext4_create_inline_data
ext4_write_inline_data
ext4_set_inode_state -> set inode EXT4_STATE_MAY_INLINE_DATA
3. writepages
__ext4_ioctl
ext4_alloc_da_blocks
filemap_flush
filemap_fdatawrite_wbc
do_writepages
ext4_writepages
if (ext4_has_inline_data(inode))
BUG_ON(ext4_test_inode_state(inode, EXT4_STATE_MAY_INLINE_DATA))
The root cause of this issue is we destory inline data until call
ext4_writepages under delay allocation mode. But there maybe already
convert from inline to extent. To solve this issue, we call
filemap_flush first..

Summary
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: renesas: rzn1: Fix possible null-ptr-deref in sh_pfc_map_resources()
It will cause null-ptr-deref when using 'res', if platform_get_resource()
returns NULL, so move using 'res' after devm_ioremap_resource() that
will check it to avoid null-ptr-deref.
And use devm_platform_get_and_ioremap_resource() to simplify code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mxser: fix xmit_buf leak in activate when LSR == 0xff
When LSR is 0xff in ->activate() (rather unlike), we return an error.
Provided ->shutdown() is not called when ->activate() fails, nothing
actually frees the buffer in this case.
Fix this by properly freeing the buffer in a designated label. We jump
there also from the "!info->type" if now too.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sysctl: Fix data races in proc_douintvec().
A sysctl variable is accessed concurrently, and there is always a chance
of data-race. So, all readers and writers need some basic protection to
avoid load/store-tearing.
This patch changes proc_douintvec() to use READ_ONCE() and WRITE_ONCE()
internally to fix data-races on the sysctl side. For now, proc_douintvec()
itself is tolerant to a data-race, but we still need to add annotations on
the other subsystem's side.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Make sure trace_printk() can output as soon as it can be used
Currently trace_printk() can be used as soon as early_trace_init() is
called from start_kernel(). But if a crash happens, and
"ftrace_dump_on_oops" is set on the kernel command line, all you get will
be:
[ 0.456075] <idle>-0 0dN.2. 347519us : Unknown type 6
[ 0.456075] <idle>-0 0dN.2. 353141us : Unknown type 6
[ 0.456075] <idle>-0 0dN.2. 358684us : Unknown type 6
This is because the trace_printk() event (type 6) hasn't been registered
yet. That gets done via an early_initcall(), which may be early, but not
early enough.
Instead of registering the trace_printk() event (and other ftrace events,
which are not trace events) via an early_initcall(), have them registered at
the same time that trace_printk() can be used. This way, if there is a
crash before early_initcall(), then the trace_printk()s will actually be
useful.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix insufficient bounds propagation from adjust_scalar_min_max_vals
Kuee reported a corner case where the tnum becomes constant after the call
to __reg_bound_offset(), but the register's bounds are not, that is, its
min bounds are still not equal to the register's max bounds.
This in turn allows to leak pointers through turning a pointer register as
is into an unknown scalar via adjust_ptr_min_max_vals().
Before:
func#0 @0
0: R1=ctx(off=0,imm=0,umax=0,var_off=(0x0; 0x0)) R10=fp(off=0,imm=0,umax=0,var_off=(0x0; 0x0))
0: (b7) r0 = 1 ; R0_w=scalar(imm=1,umin=1,umax=1,var_off=(0x1; 0x0))

2: (87) r3 = -r3 ; R3_w=scalar()
3: (87) r3 = -r3 ; R3_w=scalar()
4: (47) r3 |= 32767 ; R3_w=scalar(smin=-9223372036854743041,umin=32767,var_off=(0x7fff; 0xffffffffffff8000),s32_min=-2147450881)
5: (75) if r3 s>= 0x0 goto pc+1 ; R3_w=scalar(umin=9223372036854808575,var_off=(0x8000000000007fff; 0x7fffffffffff8000),s32_min=-2147450881,u32_min=32767)
6: (95) exit
from 5 to 7: R0=scalar(imm=1,umin=1,umax=1,var_off=(0x1; 0x0)) R1=ctx(off=0,imm=0,umax=0,var_off=(0x0; 0x0)) R3=scalar(umin=32767,umax=9223372036854775807,var_off=(0x7fff; 0x7fffffffffff8000),s32_min=-2147450881) R10=fp(off=0,imm=0,umax=0,var_off=(0x0; 0x0))
7: (d5) if r3 s<= 0x8000 goto pc+1 ; R3=scalar(umin=32769,umax=9223372036854775807,var_off=(0x7fff; 0x7fffffffffff8000),s32_min=-2147450881,u32_min=32767)
8: (95) exit
from 7 to 9: R0=scalar(imm=1,umin=1,umax=1,var_off=(0x1; 0x0)) R1=ctx(off=0,imm=0,umax=0,var_off=(0x0; 0x0)) R3=scalar(umin=32767,umax=32768,var_off=(0x7fff; 0x8000)) R10=fp(off=0,imm=0,umax=0,var_off=(0x0; 0x0))
9: (07) r3 += -32767 ; R3_w=scalar(imm=0,umax=1,var_off=(0x0; 0x0)) <--- [*]
10: (95) exit
What can be seen here is that R3=scalar(umin=32767,umax=32768,var_off=(0x7fff;
0x8000)) after the operation R3 += -32767 results in a 'malformed' constant, that
is, R3_w=scalar(imm=0,umax=1,var_off=(0x0; 0x0)). Intersecting with var_off has
not been done at that point via __update_reg_bounds(), which would have improved
the umax to be equal to umin.
Refactor the tnum <> min/max bounds information flow into a reg_bounds_sync()
helper and use it consistently everywhere. After the fix, bounds have been
corrected to R3_w=scalar(imm=0,umax=0,var_off=(0x0; 0x0)) and thus the register
is regarded as a 'proper' constant scalar of 0.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dp: populate connector of struct dp_panel
DP CTS test case 4.2.2.6 has valid edid with bad checksum on purpose
and expect DP source return correct checksum. During drm edid read,
correct edid checksum is calculated and stored at
connector::real_edid_checksum.
The problem is struct dp_panel::connector never be assigned, instead the
connector is stored in struct msm_dp::connector. When we run compliance
testing test case 4.2.2.6 dp_panel_handle_sink_request() won't have a valid
edid set in struct dp_panel::edid so we'll try to use the connectors
real_edid_checksum and hit a NULL pointer dereference error because the
connector pointer is never assigned.
Changes in V2:
-- populate panel connector at msm_dp_modeset_init() instead of at dp_panel_read_sink_caps()
Changes in V3:
-- remove unhelpful kernel crash trace commit text
-- remove renaming dp_display parameter to dp
Changes in V4:
-- add more details to commit text
Changes in v10:
-- group into one series
Changes in v11:
-- drop drm/msm/dp: dp_link_parse_sink_count() return immediately if aux read

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix resource leak in lpfc_sli4_send_seq_to_ulp()
If no handler is found in lpfc_complete_unsol_iocb() to match the rctl of a
received frame, the frame is dropped and resources are leaked.
Fix by returning resources when discarding an unhandled frame type. Update
lpfc_fc_frame_check() handling of NOP basic link service.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ath11k: free peer for station when disconnect from AP for QCA6390/WCN6855
Commit b4a0f54156ac ("ath11k: move peer delete after vdev stop of station
for QCA6390 and WCN6855") is to fix firmware crash by changing the WMI
command sequence, but actually skip all the peer delete operation, then
it lead commit 58595c9874c6 ("ath11k: Fixing dangling pointer issue upon
peer delete failure") not take effect, and then happened a use-after-free
warning from KASAN. because the peer->sta is not set to NULL and then used
later.
Change to only skip the WMI_PEER_DELETE_CMDID for QCA6390/WCN6855.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: zynqmp_dma: In struct zynqmp_dma_chan fix desc_size data type
In zynqmp_dma_alloc/free_chan_resources functions there is a
potential overflow in the below expressions.
dma_alloc_coherent(chan->dev, (2 * chan->desc_size *
ZYNQMP_DMA_NUM_DESCS),
&chan->desc_pool_p, GFP_KERNEL);
dma_free_coherent(chan->dev,(2 * ZYNQMP_DMA_DESC_SIZE(chan) *
ZYNQMP_DMA_NUM_DESCS),
chan->desc_pool_v, chan->desc_pool_p);
The arguments desc_size and ZYNQMP_DMA_NUM_DESCS were 32 bit. Though
this overflow condition is not observed but it is a potential problem
in the case of 32-bit multiplication. Hence fix it by changing the
desc_size data type to size_t.
In addition to coverity fix it also reuse ZYNQMP_DMA_DESC_SIZE macro in
dma_alloc_coherent API argument.
Addresses-Coverity: Event overflow_before_widen.

Summary
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: renesas: core: Fix possible null-ptr-deref in sh_pfc_map_resources()
It will cause null-ptr-deref when using 'res', if platform_get_resource()
returns NULL, so move using 'res' after devm_ioremap_resource() that
will check it to avoid null-ptr-deref.
And use devm_platform_get_and_ioremap_resource() to simplify code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: act_ct: fix ref leak when switching zones
When switching zones or network namespaces without doing a ct clear in
between, it is now leaking a reference to the old ct entry. That's
because tcf_ct_skb_nfct_cached() returns false and
tcf_ct_flow_table_lookup() may simply overwrite it.
The fix is to, as the ct entry is not reusable, free it already at
tcf_ct_skb_nfct_cached().

The above warning triggered because the current imc-pmu code uses mutex
lock in interrupt disabled sections. The function mutex_lock()
internally calls __might_resched(), which will check if IRQs are
disabled and in case IRQs are disabled, it will trigger the warning.
Fix the issue by changing the mutex lock to spinlock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ibmvnic: Don't reference skb after sending to VIOS
Previously, after successfully flushing the xmit buffer to VIOS,
the tx_bytes stat was incremented by the length of the skb.
It is invalid to access the skb memory after sending the buffer to
the VIOS because, at any point after sending, the VIOS can trigger
an interrupt to free this memory. A race between reading skb->len
and freeing the skb is possible (especially during LPM) and will
result in use-after-free:

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: host: Stop setting the ACPI companion
It is no longer needed. The sysdev pointer is now used when
assigning the ACPI companions to the xHCI ports and USB
devices.
Assigning the ACPI companion here resulted in the
fwnode->secondary pointer to be replaced also for the parent
dwc3 device since the primary fwnode (the ACPI companion)
was shared. That was unintentional and it created potential
side effects like resource leaks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: rt7*-sdw: harden jack_detect_handler
Realtek headset codec drivers typically check if the card is
instantiated before proceeding with the jack detection.
The rt700, rt711 and rt711-sdca are however missing a check on the
card pointer, which can lead to NULL dereferences encountered in
driver bind/unbind tests.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sysctl: Fix data-races in proc_dou8vec_minmax().
A sysctl variable is accessed concurrently, and there is always a chance
of data-race. So, all readers and writers need some basic protection to
avoid load/store-tearing.
This patch changes proc_dou8vec_minmax() to use READ_ONCE() and
WRITE_ONCE() internally to fix data-races on the sysctl side. For now,
proc_dou8vec_minmax() itself is tolerant to a data-race, but we still
need to add annotations on the other subsystem's side.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix premature hw access after PCI error
After a recoverable PCI error has been detected and recovered, qla driver
needs to check to see if the error condition still persist and/or wait
for the OS to give the resume signal.

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: clk-rcg2: Update logic to calculate D value for RCG
The display pixel clock has a requirement on certain newer platforms to
support M/N as (2/3) and the final D value calculated results in
underflow errors.
As the current implementation does not check for D value is within
the accepted range for a given M & N value. Update the logic to
calculate the final D value based on the range.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: dvbdev: prevent the risk of out of memory access
The dvbdev contains a static variable used to store dvb minors.
The behavior of it depends if CONFIG_DVB_DYNAMIC_MINORS is set
or not. When not set, dvb_register_device() won't check for
boundaries, as it will rely that a previous call to
dvb_register_adapter() would already be enforcing it.
On a similar way, dvb_device_open() uses the assumption
that the register functions already did the needed checks.
This can be fragile if some device ends using different
calls. This also generate warnings on static check analysers
like Coverity.
So, add explicit guards to prevent potential risk of OOM issues.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: ccree - Fix use after free in cc_cipher_exit()
kfree_sensitive(ctx_p->user.key) will free the ctx_p->user.key. But
ctx_p->user.key is still used in the next line, which will lead to a
use after free.
We can call kfree_sensitive() after dev_dbg() to avoid the uaf.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: bgmac: Fix refcount leak in bcma_mdio_mii_register
of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Fix more uncharged while msg has more_data
In tcp_bpf_send_verdict(), if msg has more data after
tcp_bpf_sendmsg_redir():
tcp_bpf_send_verdict()
tosend = msg->sg.size //msg->sg.size = 22220
case __SK_REDIRECT:
sk_msg_return() //uncharged msg->sg.size(22220) sk->sk_forward_alloc
tcp_bpf_sendmsg_redir() //after tcp_bpf_sendmsg_redir, msg->sg.size=11000
goto more_data;
tosend = msg->sg.size //msg->sg.size = 11000
case __SK_REDIRECT:
sk_msg_return() //uncharged msg->sg.size(11000) to sk->sk_forward_alloc
The msg->sg.size(11000) has been uncharged twice, to fix we can charge the
remaining msg->sg.size before goto more data.
This issue can cause the following info:

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: fix dangling sco_conn and use-after-free in sco_sock_timeout
Connecting the same socket twice consecutively in sco_sock_connect()
could lead to a race condition where two sco_conn objects are created
but only one is associated with the socket. If the socket is closed
before the SCO connection is established, the timer associated with the
dangling sco_conn object won't be canceled. As the sock object is being
freed, the use-after-free problem happens when the timer callback
function sco_sock_timeout() accesses the socket. Here's the call trace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/mediatek: Fix NULL pointer dereference when printing dev_name
When larbdev is NULL (in the case I hit, the node is incorrectly set
iommus = <&iommu NUM>), it will cause device_link_add() fail and
kernel crashes when we try to print dev_name(larbdev).
Let's fail the probe if a larbdev is NULL to avoid invalid inputs from
dts.
It should work for normal correct setting and avoid the crash caused
by my incorrect setting.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: mdio: unexport __init-annotated mdio_bus_init()
EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.
modpost used to detect it, but it has been broken for a decade.
Recently, I fixed modpost so it started to warn it again, then this
showed up in linux-next builds.
There are two ways to fix it:
- Remove __init
- Remove EXPORT_SYMBOL
I chose the latter for this case because the only in-tree call-site,
drivers/net/phy/phy_device.c is never compiled as modular.
(CONFIG_PHYLIB is boolean)

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: tun: unlink NAPI from device on destruction
Syzbot found a race between tun file and device destruction.
NAPIs live in struct tun_file which can get destroyed before
the netdev so we have to del them explicitly. The current
code is missing deleting the NAPI if the queue was detached
first.

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: Fix potential deadlock in blk_ia_range_sysfs_show()
When being read, a sysfs attribute is already protected against removal
with the kobject node active reference counter. As a result, in
blk_ia_range_sysfs_show(), there is no need to take the queue sysfs
lock when reading the value of a range attribute. Using the queue sysfs
lock in this function creates a potential deadlock situation with the
disk removal, something that a lockdep signals with a splat when the
device is removed:
[ 760.703551] Possible unsafe locking scenario:
[ 760.703551]
[ 760.703554] CPU0 CPU1
[ 760.703556] ---- ----
[ 760.703558] lock(&q->sysfs_lock);
[ 760.703565] lock(kn->active#385);
[ 760.703573] lock(&q->sysfs_lock);
[ 760.703579] lock(kn->active#385);
[ 760.703587]
[ 760.703587] *** DEADLOCK ***
Solve this by removing the mutex_lock()/mutex_unlock() calls from
blk_ia_range_sysfs_show().

---[ end trace d4b8409def9b8b1f ]---
The reason for this warning is the attempt to get the chip->dev reference
in tpm_common_write() although the reference counter is already zero.
Since commit 8979b02aaf1d ("tpm: Fix reference count to main device") the
extra reference used to prevent a premature zero counter is never taken,
because the required TPM_CHIP_FLAG_TPM2 flag is never set.
Fix this by moving the TPM 2 character device handling from
tpm_chip_alloc() to tpm_add_char_device() which is called at a later point
in time when the flag has been set in case of TPM2.
Commit fdc915f7f719 ("tpm: expose spaces via a device link /dev/tpmrm<n>")
already introduced function tpm_devs_release() to release the extra
reference but did not implement the required put on chip->devs that results
in the call of this function.
Fix this by putting chip->devs in tpm_chip_unregister().
Finally move the new implementation for the TPM 2 handling into a new
function to avoid multiple checks for the TPM_CHIP_FLAG_TPM2 flag in the
good case and error cases.

Summary
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: Fix the svc_deferred_event trace class
Fix a NULL deref crash that occurs when an svc_rqst is deferred
while the sunrpc tracing subsystem is enabled. svc_revisit() sets
dr->xprt to NULL, so it can't be relied upon in the tracepoint to
provide the remote's address.
Unfortunately we can't revert the "svc_deferred_class" hunk in
commit ece200ddd54b ("sunrpc: Save remote presentation address in
svc_xprt for trace events") because there is now a specific check
of event format specifiers for unsafe dereferences. The warning
that check emits is:
event svc_defer_recv has unsafe dereference of argument 1
A "%pISpc" format specifier with a "struct sockaddr *" is indeed
flagged by this check.
Instead, take the brute-force approach used by the svcrdma_qp_error
tracepoint. Convert the dr::addr field into a presentation address
in the TP_fast_assign() arm of the trace event, and store that as
a string. This fix can be backported to -stable kernels.
In the meantime, commit c6ced22997ad ("tracing: Update print fmt
check to handle new __get_sockaddr() macro") is now in v5.18, so
this wonky fix can be replaced with __sockaddr() and friends
properly during the v5.19 merge window.

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: compat: Do not treat syscall number as ESR_ELx for a bad syscall
If a compat process tries to execute an unknown system call above the
__ARM_NR_COMPAT_END number, the kernel sends a SIGILL signal to the
offending process. Information about the error is printed to dmesg in
compat_arm_syscall() -> arm64_notify_die() -> arm64_force_sig_fault() ->
arm64_show_signal().
arm64_show_signal() interprets a non-zero value for
current->thread.fault_code as an exception syndrome and displays the
message associated with the ESR_ELx.EC field (bits 31:26).
current->thread.fault_code is set in compat_arm_syscall() ->
arm64_notify_die() with the bad syscall number instead of a valid ESR_ELx
value. This means that the ESR_ELx.EC field has the value that the user set
for the syscall number and the kernel can end up printing bogus exception
messages*. For example, for the syscall number 0x68000000, which evaluates
to ESR_ELx.EC value of 0x1A (ESR_ELx_EC_FPAC) the kernel prints this error:
[ 18.349161] syscall[300]: unhandled exception: ERET/ERETAA/ERETAB, ESR 0x68000000, Oops - bad compat syscall(2) in syscall[10000+50000]
[ 18.350639] CPU: 2 PID: 300 Comm: syscall Not tainted 5.18.0-rc1 #79
[ 18.351249] Hardware name: Pine64 RockPro64 v2.0 (DT)
[..]
which is misleading, as the bad compat syscall has nothing to do with
pointer authentication.
Stop arm64_show_signal() from printing exception syndrome information by
having compat_arm_syscall() set the ESR_ELx value to 0, as it has no
meaning for an invalid system call number. The example above now becomes:
[ 19.935275] syscall[301]: unhandled exception: Oops - bad compat syscall(2) in syscall[10000+50000]
[ 19.936124] CPU: 1 PID: 301 Comm: syscall Not tainted 5.18.0-rc1-00005-g7e08006d4102 #80
[ 19.936894] Hardware name: Pine64 RockPro64 v2.0 (DT)
[..]
which although shows less information because the syscall number,
wrongfully advertised as the ESR value, is missing, it is better than
showing plainly wrong information. The syscall number can be easily
obtained with strace.
*A 32-bit value above or equal to 0x8000_0000 is interpreted as a negative
integer in compat_arm_syscal() and the condition scno < __ARM_NR_COMPAT_END
evaluates to true; the syscall will exit to userspace in this case with the
ENOSYS error code instead of arm64_notify_die() being called.

Information about the error is printed to dmesg in\ncompat_arm_syscall() -\u003e arm64_notify_die() -\u003e arm64_force_sig_fault() -\u003e\narm64_show_signal().\n\narm64_show_signal() interprets a non-zero value for\ncurrent-\u003ethread.fault_code as an exception syndrome and displays the\nmessage associated with the ESR_ELx.EC field (bits 31:26).\ncurrent-\u003ethread.fault_code is set in compat_arm_syscall() -\u003e\narm64_notify_die() with the bad syscall number instead of a valid ESR_ELx\nvalue. This means that the ESR_ELx.EC field has the value that the user set\nfor the syscall number and the kernel can end up printing bogus exception\nmessages*. For example, for the syscall number 0x68000000, which evaluates\nto ESR_ELx.EC value of 0x1A (ESR_ELx_EC_FPAC) the kernel prints this error:\n\n[ 18.349161] syscall[300]: unhandled exception: ERET/ERETAA/ERETAB, ESR 0x68000000, Oops - bad compat syscall(2) in syscall[10000+50000]\n[ 18.350639] CPU: 2 PID: 300 Comm: syscall Not tainted 5.18.0-rc1 #79\n[ 18.351249] Hardware name: Pine64 RockPro64 v2.0 (DT)\n[..]\n\nwhich is misleading, as the bad compat syscall has nothing to do with\npointer authentication.\n\nStop arm64_show_signal() from printing exception syndrome information by\nhaving compat_arm_syscall() set the ESR_ELx value to 0, as it has no\nmeaning for an invalid system call number. The example above now becomes:\n\n[ 19.935275] syscall[301]: unhandled exception: Oops - bad compat syscall(2) in syscall[10000+50000]\n[ 19.936124] CPU: 1 PID: 301 Comm: syscall Not tainted 5.18.0-rc1-00005-g7e08006d4102 #80\n[ 19.936894] Hardware name: Pine64 RockPro64 v2.0 (DT)\n[..]\n\nwhich although shows less information because the syscall number,\nwrongfully advertised as the ESR value, is missing, it is better than\nshowing plainly wrong information. The syscall number can be easily\nobtained with strace.\n\n*A 32-bit value above or equal to 0x8000_0000 is interpreted as a negative\ninteger in compat_arm_syscal() and the condition scno \u003c __ARM_NR_COMPAT_END\nevaluates to true; the syscall will exit to userspace in this case with the\nENOSYS error code instead of arm64_notify_die() being called."

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Drop WARNs that assert a triple fault never "escapes" from L2
Remove WARNs that sanity check that KVM never lets a triple fault for L2
escape and incorrectly end up in L1. In normal operation, the sanity
check is perfectly valid, but it incorrectly assumes that it's impossible
for userspace to induce KVM_REQ_TRIPLE_FAULT without bouncing through
KVM_RUN (which guarantees kvm_check_nested_state() will see and handle
the triple fault).
The WARN can currently be triggered if userspace injects a machine check
while L2 is active and CR4.MCE=0. And a future fix to allow save/restore
of KVM_REQ_TRIPLE_FAULT, e.g. so that a synthesized triple fault isn't
lost on migration, will make it trivially easy for userspace to trigger
the WARN.
Clearing KVM_REQ_TRIPLE_FAULT when forcibly leaving guest mode is
tempting, but wrong, especially if/when the request is saved/restored,
e.g. if userspace restores events (including a triple fault) and then
restores nested state (which may forcibly leave guest mode). Ignoring
the fact that KVM doesn't currently provide the necessary APIs, it's
userspace's responsibility to manage pending events during save/restore.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: xfrm: unexport __init-annotated xfrm4_protocol_init()
EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.
modpost used to detect it, but it has been broken for a decade.
Recently, I fixed modpost so it started to warn it again, then this
showed up in linux-next builds.
There are two ways to fix it:
- Remove __init
- Remove EXPORT_SYMBOL
I chose the latter for this case because the only in-tree call-site,
net/ipv4/xfrm4_policy.c is never compiled as modular.
(CONFIG_XFRM is boolean)

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtlwifi: remove unused check_buddy_priv
Commit 2461c7d60f9f ("rtlwifi: Update header file") introduced a global
list of private data structures.
Later on, commit 26634c4b1868 ("rtlwifi Modify existing bits to match
vendor version 2013.02.07") started adding the private data to that list at
probe time and added a hook, check_buddy_priv to find the private data from
a similar device.
However, that function was never used.
Besides, though there is a lock for that list, it is never used. And when
the probe fails, the private data is never removed from the list. This
would cause a second probe to access freed memory.
Remove the unused hook, structures and members, which will prevent the
potential race condition on the list and its corruption during a second
probe when probe fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: stmmac: fix altr_tse_pcs function when using a fixed-link
When using a fixed-link, the altr_tse_pcs driver crashes
due to null-pointer dereference as no phy_device is provided to
tse_pcs_fix_mac_speed function. Fix this by adding a check for
phy_dev before calling the tse_pcs_fix_mac_speed() function.
Also clean up the tse_pcs_fix_mac_speed function a bit. There is
no need to check for splitter_base and sgmii_adapter_base
because the driver will fail if these 2 variables are not
derived from the device tree.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix potential double free in create_var_ref()
In create_var_ref(), init_var_ref() is called to initialize the fields
of variable ref_field, which is allocated in the previous function call
to create_hist_field(). Function init_var_ref() allocates the
corresponding fields such as ref_field->system, but frees these fields
when the function encounters an error. The caller later calls
destroy_hist_field() to conduct error handling, which frees the fields
and the variable itself. This results in double free of the fields which
are already freed in the previous function.
Fix this by storing NULL to the corresponding fields when they are freed
in init_var_ref().

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btmtksdio: Fix kernel oops in btmtksdio_interrupt
Fix the following kernel oops in btmtksdio_interrrupt
[ 14.339134] btmtksdio_interrupt+0x28/0x54
[ 14.339139] process_sdio_pending_irqs+0x68/0x1a0
[ 14.339144] sdio_irq_work+0x40/0x70
[ 14.339154] process_one_work+0x184/0x39c
[ 14.339160] worker_thread+0x228/0x3e8
[ 14.339168] kthread+0x148/0x3ac
[ 14.339176] ret_from_fork+0x10/0x30
That happened because hdev->power_on is already called before
sdio_set_drvdata which btmtksdio_interrupt handler relies on is not
properly set up.
The details are shown as the below: hci_register_dev would run
queue_work(hdev->req_workqueue, &hdev->power_on) as WQ_HIGHPRI
workqueue_struct to complete the power-on sequeunce and thus hci_power_on
may run before sdio_set_drvdata is done in btmtksdio_probe.
The hci_dev_do_open in hci_power_on would initialize the device and enable
the interrupt and thus it is possible that btmtksdio_interrupt is being
called right before sdio_set_drvdata is filled out.
When btmtksdio_interrupt is being called and sdio_set_drvdata is not filled
, the kernel oops is going to happen because btmtksdio_interrupt access an
uninitialized pointer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gtp: Suppress list corruption splat in gtp_net_exit_batch_rtnl().
Brad Spengler reported the list_del() corruption splat in
gtp_net_exit_batch_rtnl(). [0]
Commit eb28fd76c0a0 ("gtp: Destroy device along with udp socket's netns
dismantle.") added the for_each_netdev() loop in gtp_net_exit_batch_rtnl()
to destroy devices in each netns as done in geneve and ip tunnels.
However, this could trigger ->dellink() twice for the same device during
->exit_batch_rtnl().
Say we have two netns A & B and gtp device B that resides in netns B but
whose UDP socket is in netns A.
1. cleanup_net() processes netns A and then B.
2. gtp_net_exit_batch_rtnl() finds the device B while iterating
netns A's gn->gtp_dev_list and calls ->dellink().
[ device B is not yet unlinked from netns B
as unregister_netdevice_many() has not been called. ]
3. gtp_net_exit_batch_rtnl() finds the device B while iterating
netns B's for_each_netdev() and calls ->dellink().
gtp_dellink() cleans up the device's hash table, unlinks the dev from
gn->gtp_dev_list, and calls unregister_netdevice_queue().
Basically, calling gtp_dellink() multiple times is fine unless
CONFIG_DEBUG_LIST is enabled.
Let's remove for_each_netdev() in gtp_net_exit_batch_rtnl() and
delegate the destruction to default_device_exit_batch() as done
in bareudp.

Summary
In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8712: fix a potential memory leak in r871xu_drv_init()
In r871xu_drv_init(), if r8712_init_drv_sw() fails, then the memory
allocated by r8712_alloc_io_queue() in r8712_usb_dvobj_init() is not
properly released as there is no action will be performed by
r8712_usb_dvobj_deinit().
To properly release it, we should call r8712_free_io_queue() in
r8712_usb_dvobj_deinit().
Besides, in r871xu_dev_remove(), r8712_usb_dvobj_deinit() will be called
by r871x_dev_unload() under condition `padapter->bup` and
r8712_free_io_queue() is called by r8712_free_drv_sw().
However, r8712_usb_dvobj_deinit() does not rely on `padapter->bup` and
calling r8712_free_io_queue() in r8712_free_drv_sw() is negative for
better understading the code.
So I move r8712_usb_dvobj_deinit() into r871xu_dev_remove(), and remove
r8712_free_io_queue() from r8712_free_drv_sw().

Summary
In the Linux kernel, the following vulnerability has been resolved:
platform/x86: thinkpad_acpi: Fix a memory leak of EFCH MMIO resource
Unlike release_mem_region(), a call to release_resource() does not
free the resource, so it has to be freed explicitly to avoid a memory
leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: PAD: fix crash in exit_round_robin()
The kernel occasionally crashes in cpumask_clear_cpu(), which is called
within exit_round_robin(), because when executing clear_bit(nr, addr) with
nr set to 0xffffffff, the address calculation may cause misalignment within
the memory, leading to access to an invalid memory address.

To fix this, ensure that tsk_in_cpu[tsk_index] != -1 before calling
cpumask_clear_cpu() in exit_round_robin(), just as it is done in
round_robin_cpu().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ima: Fix potential memory leak in ima_init_crypto()
On failure to allocate the SHA1 tfm, IMA fails to initialize and exits
without freeing the ima_algo_array. Add the missing kfree() for
ima_algo_array to avoid the potential memory leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: musb: sunxi: Fix accessing an released usb phy
Commit 6ed05c68cbca ("usb: musb: sunxi: Explicitly release USB PHY on
exit") will cause that usb phy @glue->xceiv is accessed after released.
1) register platform driver @sunxi_musb_driver
// get the usb phy @glue->xceiv
sunxi_musb_probe() -> devm_usb_get_phy().
2) register and unregister platform driver @musb_driver
musb_probe() -> sunxi_musb_init()
use the phy here
//the phy is released here
musb_remove() -> sunxi_musb_exit() -> devm_usb_put_phy()
3) register @musb_driver again
musb_probe() -> sunxi_musb_init()
use the phy here but the phy has been released at 2).
...
Fixed by reverting the commit, namely, removing devm_usb_put_phy()
from sunxi_musb_exit().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: pcm: Fix races among concurrent hw_params and hw_free calls
Currently we have neither proper check nor protection against the
concurrent calls of PCM hw_params and hw_free ioctls, which may result
in a UAF. Since the existing PCM stream lock can't be used for
protecting the whole ioctl operations, we need a new mutex to protect
those racy calls.
This patch introduced a new mutex, runtime->buffer_mutex, and applies
it to both hw_params and hw_free ioctl code paths. Along with it, the
both functions are slightly modified (the mmap_count check is moved
into the state-check block) for code simplicity.

Along with it, the\nboth functions are slightly modified (the mmap_count check is moved\ninto the state-check block) for code simplicity."

Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio_console: eliminate anonymous module_init & module_exit
Eliminate anonymous module_init() and module_exit(), which can lead to
confusion or ambiguity when reading System.map, crashes/oops/bugs,
or an initcall_debug log.
Give each of these init and exit functions unique driver-specific
names to eliminate the anonymous names.
Example 1: (System.map)
ffffffff832fc78c t init
ffffffff832fc79e t init
ffffffff832fc8f8 t init
Example 2: (initcall_debug log)
calling init+0x0/0x12 @ 1
initcall init+0x0/0x12 returned 0 after 15 usecs
calling init+0x0/0x60 @ 1
initcall init+0x0/0x60 returned 0 after 2 usecs
calling init+0x0/0x9a @ 1
initcall init+0x0/0x9a returned 0 after 74 usecs

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: target: tcmu: Fix possible page UAF
tcmu_try_get_data_page() looks up pages under cmdr_lock, but it does not
take refcount properly and just returns page pointer. When
tcmu_try_get_data_page() returns, the returned page may have been freed by
tcmu_blocks_release().
We need to get_page() under cmdr_lock to avoid concurrent
tcmu_blocks_release().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ath11k: Change max no of active probe SSID and BSSID to fw capability
The maximum number of SSIDs in a for active probe requests is currently
reported as 16 (WLAN_SCAN_PARAMS_MAX_SSID) when registering the driver.
The scan_req_params structure only has the capacity to hold 10 SSIDs.
This leads to a buffer overflow which can be triggered from
wpa_supplicant in userspace. When copying the SSIDs into the
scan_req_params structure in the ath11k_mac_op_hw_scan route, it can
overwrite the extraie pointer.
Firmware supports 16 ssid * 4 bssid, for each ssid 4 bssid combo probe
request will be sent, so totally 64 probe requests supported. So
set both max ssid and bssid to 16 and 4 respectively. Remove the
redundant macros of ssid and bssid.
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.7.0.1-01300-QCAHKSWPL_SILICONZ-1

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: Check the count value of channel spec to prevent out-of-bounds reads
This patch fixes slab-out-of-bounds reads in brcmfmac that occur in
brcmf_construct_chaninfo() and brcmf_enable_bw40_2g() when the count
value of channel specifications provided by the device is greater than
the length of 'list->element[]', decided by the size of the 'list'
allocated with kzalloc(). The patch adds checks that make the functions
free the buffer and return -EINVAL if that is the case. Note that the
negative return is handled by the caller, brcmf_setup_wiphybands() or
brcmf_cfg80211_attach().
Found by a modified version of syzkaller.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: inet6: do not leave a dangling sk pointer in inet6_create()
sock_init_data() attaches the allocated sk pointer to the provided sock
object. If inet6_create() fails later, the sk object is released, but the
sock object retains the dangling sk pointer, which may cause use-after-free
later.
Clear the sock sk pointer on error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Skip task with pid=1 in send_signal_common()
The following kernel panic can be triggered when a task with pid=1 attaches
a prog that attempts to send killing signal to itself, also see [1] for more
details:
Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b
CPU: 3 PID: 1 Comm: systemd Not tainted 6.1.0-09652-g59fe41b5255f #148

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ipv6: unexport __init-annotated seg6_hmac_init()
EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.
modpost used to detect it, but it has been broken for a decade.
Recently, I fixed modpost so it started to warn it again, then this
showed up in linux-next builds.
There are two ways to fix it:
- Remove __init
- Remove EXPORT_SYMBOL
I chose the latter for this case because the caller (net/ipv6/seg6.c)
and the callee (net/ipv6/seg6_hmac.c) belong to the same module.
It seems an internal function call in ipv6.ko.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/khugepaged: fix ->anon_vma race
If an ->anon_vma is attached to the VMA, collapse_and_free_pmd() requires
it to be locked.
Page table traversal is allowed under any one of the mmap lock, the
anon_vma lock (if the VMA is associated with an anon_vma), and the
mapping lock (if the VMA is associated with a mapping); and so to be
able to remove page tables, we must hold all three of them.
retract_page_tables() bails out if an ->anon_vma is attached, but does
this check before holding the mmap lock (as the comment above the check
explains).
If we racily merged an existing ->anon_vma (shared with a child
process) from a neighboring VMA, subsequent rmap traversals on pages
belonging to the child will be able to see the page tables that we are
concurrently removing while assuming that nothing else can access them.
Repeat the ->anon_vma check once we hold the mmap lock to ensure that
there really is no concurrent page table access.
Hitting this bug causes a lockdep warning in collapse_and_free_pmd(),
in the line "lockdep_assert_held_write(&vma->anon_vma->root->rwsem)".
It can also lead to use-after-free access.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp_bpf: Fix the sk_mem_uncharge logic in tcp_bpf_sendmsg
The current sk memory accounting logic in __SK_REDIRECT is pre-uncharging
tosend bytes, which is either msg->sg.size or a smaller value apply_bytes.
Potential problems with this strategy are as follows:
- If the actual sent bytes are smaller than tosend, we need to charge some
bytes back, as in line 487, which is okay but seems not clean.
- When tosend is set to apply_bytes, as in line 417, and (ret < 0), we may
miss uncharging (msg->sg.size - apply_bytes) bytes.
[...]
415 tosend = msg->sg.size;
416 if (psock->apply_bytes && psock->apply_bytes < tosend)
417 tosend = psock->apply_bytes;
[...]
443 sk_msg_return(sk, msg, tosend);
444 release_sock(sk);
446 origsize = msg->sg.size;
447 ret = tcp_bpf_sendmsg_redir(sk_redir, redir_ingress,
448 msg, tosend, flags);
449 sent = origsize - msg->sg.size;
[...]
454 lock_sock(sk);
455 if (unlikely(ret < 0)) {
456 int free = sk_msg_free_nocharge(sk, msg);
458 if (!cork)
459 *copied -= free;
460 }
[...]
487 if (eval == __SK_REDIRECT)
488 sk_mem_charge(sk, tosend - sent);
[...]
When running the selftest test_txmsg_redir_wait_sndmem with txmsg_apply,
the following warning will be reported:

---[ end trace 0000000000000000 ]---
In __SK_REDIRECT, a more concise way is delaying the uncharging after sent
bytes are finalized, and uncharge this value. When (ret < 0), we shall
invoke sk_msg_free.
Same thing happens in case __SK_DROP, when tosend is set to apply_bytes,
we may miss uncharging (msg->sg.size - apply_bytes) bytes. The same
warning will be reported in selftest.
[...]
468 case __SK_DROP:
469 default:
470 sk_msg_free_partial(sk, msg, tosend);
471 sk_msg_apply_bytes(psock, tosend);
472 *copied -= (tosend + delta);
473 return -EACCES;
[...]
So instead of sk_msg_free_partial we can do sk_msg_free here.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: octeontx2 - remove CONFIG_DM_CRYPT check
No issues were found while using the driver with dm-crypt enabled. So
CONFIG_DM_CRYPT check in the driver can be removed.
This also fixes the NULL pointer dereference in driver release if
CONFIG_DM_CRYPT is enabled.
...
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: pcm: Check for null pointer of pointer substream before dereferencing it
Pointer substream is being dereferenced on the assignment of pointer card
before substream is being null checked with the macro PCM_RUNTIME_CHECK.
Although PCM_RUNTIME_CHECK calls BUG_ON, it still is useful to perform the
the pointer check before card is assigned.

Summary
In the Linux kernel, the following vulnerability has been resolved:
afs: Fix dynamic root getattr
The recent patch to make afs_getattr consult the server didn't account
for the pseudo-inodes employed by the dynamic root-type afs superblock
not having a volume or a server to access, and thus an oops occurs if
such a directory is stat'd.
Fix this by checking to see if the vnode->volume pointer actually points
anywhere before following it in afs_getattr().
This can be tested by stat'ing a directory in /afs. It may be
sufficient just to do "ls /afs" and the oops looks something like:
BUG: kernel NULL pointer dereference, address: 0000000000000020
...
RIP: 0010:afs_getattr+0x8b/0x14b
...
Call Trace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: atmel: Fix error handling in sam9x5_wm8731_driver_probe
The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
This function only calls of_node_put() in the regular path.
And it will cause refcount leak in error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mtd: rawnand: intel: fix possible null-ptr-deref in ebu_nand_probe()
It will cause null-ptr-deref when using 'res', if platform_get_resource()
returns NULL, so move using 'res' after devm_ioremap_resource() that
will check it to avoid null-ptr-deref.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: E-Switch, pair only capable devices
OFFLOADS paring using devcom is possible only on devices
that support LAG. Filter based on lag capabilities.
This fixes an issue where mlx5_get_next_phys_dev() was
called without holding the interface lock.
This issue was found when commit
bc4c2f2e0179 ("net/mlx5: Lag, filter non compatible devices")
added an assert that verifies the interface lock is held.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: stk1160: If start stream fails, return buffers with VB2_BUF_STATE_QUEUED
If the callback 'start_streaming' fails, then all
queued buffers in the driver should be returned with
state 'VB2_BUF_STATE_QUEUED'. Currently, they are
returned with 'VB2_BUF_STATE_ERROR' which is wrong.
Fix this. This also fixes the warning:

Summary
In the Linux kernel, the following vulnerability has been resolved:
jffs2: fix memory leak in jffs2_do_mount_fs
If jffs2_build_filesystem() in jffs2_do_mount_fs() returns an error,
we can observe the following kmemleak report:

released. Call jffs2_sum_exit() to release these resources to solve
the problem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: sch_sfq: don't allow 1 packet limit
The current implementation does not work correctly with a limit of
1. iproute2 actually checks for this and this patch adds the check in
kernel as well.
This fixes the following syzkaller reported crash:
UBSAN: array-index-out-of-bounds in net/sched/sch_sfq.c:210:6
index 65535 is out of range for type 'struct sfq_head[128]'
CPU: 0 PID: 2569 Comm: syz-executor101 Not tainted 5.10.0-smp-DEV #1

The crash can be also be reproduced with the following (with a tc
recompiled to allow for sfq limits of 1):
tc qdisc add dev dummy0 handle 1: root tbf rate 1Kbit burst 100b lat 1s
../iproute2-6.9.0/tc/tc qdisc add dev dummy0 handle 2: parent 1:10 sfq limit 1
ifconfig dummy0 up
ping -I dummy0 -f -c2 -W0.1 8.8.8.8
sleep 1
Scenario that triggers the crash:
* the first packet is sent and queued in TBF and SFQ; qdisc qlen is 1
* TBF dequeues: it peeks from SFQ which moves the packet to the
gso_skb list and keeps qdisc qlen set to 1. TBF is out of tokens so
it schedules itself for later.
* the second packet is sent and TBF tries to queues it to SFQ. qdisc
qlen is now 2 and because the SFQ limit is 1 the packet is dropped
by SFQ. At this point qlen is 1, and all of the SFQ slots are empty,
however q->tail is not NULL.
At this point, assuming no more packets are queued, when sch_dequeue
runs again it will decrement the qlen for the current empty slot
causing an underflow and the subsequent out of bounds access.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iscsi_ibft: Fix UBSAN shift-out-of-bounds warning in ibft_attr_show_nic()
When performing an iSCSI boot using IPv6, iscsistart still reads the
/sys/firmware/ibft/ethernetX/subnet-mask entry. Since the IPv6 prefix
length is 64, this causes the shift exponent to become negative,
triggering a UBSAN warning. As the concept of a subnet mask does not
apply to IPv6, the value is set to ~0 to suppress the warning message.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: avoid cycles in directory h-tree
A maliciously corrupted filesystem can contain cycles in the h-tree
stored inside a directory. That can easily lead to the kernel corrupting
tree nodes that were already verified under its hands while doing a node
split and consequently accessing unallocated memory. Fix the problem by
verifying traversed block numbers are unique.

Summary
In the Linux kernel, the following vulnerability has been resolved:
be2net: Fix buffer overflow in be_get_module_eeprom
be_cmd_read_port_transceiver_data assumes that it is given a buffer that
is at least PAGE_DATA_LEN long, or twice that if the module supports SFF
8472. However, this is not always the case.
Fix this by passing the desired offset and length to
be_cmd_read_port_transceiver_data so that we only copy the bytes once.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bnxt: Do not read past the end of test names
Test names were being concatenated based on a offset beyond the end of
the first name, which tripped the buffer overflow detection logic:
detected buffer overflow in strnlen
[...]
Call Trace:
bnxt_ethtool_init.cold+0x18/0x18
Refactor struct hwrm_selftest_qlist_output to use an actual array,
and adjust the concatenation to use snprintf() rather than a series of
strncat() calls.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum: Guard against invalid local ports
When processing events generated by the device's firmware, the driver
protects itself from events reported for non-existent local ports, but
not for the CPU port (local port 0), which exists, but does not have all
the fields as any local port.
This can result in a NULL pointer dereference when trying access
'struct mlxsw_sp_port' fields which are not initialized for CPU port.
Commit 63b08b1f6834 ("mlxsw: spectrum: Protect driver from buggy firmware")
already handled such issue by bailing early when processing a PUDE event
reported for the CPU port.
Generalize the approach by moving the check to a common function and
making use of it in all relevant places.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers: staging: rtl8192u: Fix deadlock in ieee80211_beacons_stop()
There is a deadlock in ieee80211_beacons_stop(), which is shown below:
(Thread 1) | (Thread 2)
| ieee80211_send_beacon()
ieee80211_beacons_stop() | mod_timer()
spin_lock_irqsave() //(1) | (wait a time)
... | ieee80211_send_beacon_cb()
del_timer_sync() | spin_lock_irqsave() //(2)
(wait timer to stop) | ...
We hold ieee->beacon_lock in position (1) of thread 1 and use
del_timer_sync() to wait timer to stop, but timer handler
also need ieee->beacon_lock in position (2) of thread 2.
As a result, ieee80211_beacons_stop() will block forever.
This patch extracts del_timer_sync() from the protection of
spin_lock_irqsave(), which could let timer handler to obtain
the needed lock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: Intel: Fix NULL ptr dereference when ENOMEM
Do not call snd_dma_free_pages() when snd_dma_alloc_pages() returns
-ENOMEM because it leads to a NULL pointer dereference bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
efi: Do not import certificates from UEFI Secure Boot for T2 Macs
On Apple T2 Macs, when Linux attempts to read the db and dbx efi variables
at early boot to load UEFI Secure Boot certificates, a page fault occurs
in Apple firmware code and EFI runtime services are disabled with the
following logs:
[Firmware Bug]: Page fault caused by firmware at PA: 0xffffb1edc0068000

efi: Froze efi_rts_wq and disabled EFI Runtime Services

efi: EFI Runtime Services are disabled!
integrity: Couldn't get size: 0x8000000000000015

integrity: Couldn't get size: 0x8000000000000015
integrity: Couldn't get mokx list
integrity: Couldn't get size: 0x80000000
So we avoid reading these UEFI variables and thus prevent the crash.

Summary
In the Linux kernel, the following vulnerability has been resolved:
md: Don't set mddev private to NULL in raid0 pers->free
In normal stop process, it does like this:
do_md_stop
|
__md_stop (pers->free(); mddev->private=NULL)
|
md_free (free mddev)
__md_stop sets mddev->private to NULL after pers->free. The raid device
will be stopped and mddev memory is free. But in reshape, it doesn't
free the mddev and mddev will still be used in new raid.
In reshape, it first sets mddev->private to new_pers and then runs
old_pers->free(). Now raid0 sets mddev->private to NULL in raid0_free.
The new raid can't work anymore. It will panic when dereference
mddev->private because of NULL pointer dereference.
It can panic like this:

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: tun: Fix use-after-free in tun_detach()
syzbot reported use-after-free in tun_detach() [1]. This causes call
trace like below:
==================================================================
BUG: KASAN: use-after-free in notifier_call_chain+0x1ee/0x200 kernel/notifier.c:75

The cause of the issue is that sock_put() from __tun_detach() drops
last reference count for struct net, and then notifier_call_chain()
from netdev_state_change() accesses that struct net.
This patch fixes the issue by calling sock_put() from tun_detach()
after all necessary accesses for the struct net has done.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: sd: Fix potential NULL pointer dereference
If sd_probe() sees an early error before sdkp->device is initialized,
sd_zbc_release_disk() is called. This causes a NULL pointer dereference
when sd_is_zoned() is called inside that function. Avoid this by removing
the call to sd_zbc_release_disk() in sd_probe() error path.
This change is safe and does not result in zone information memory leakage
because the zone information for a zoned disk is allocated only when
sd_revalidate_disk() is called, at which point sdkp->disk_dev is fully set,
resulting in sd_disk_release() being called when needed to cleanup a disk
zone information using sd_zbc_release_disk().

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/radeon: fix uninitialized size issue in radeon_vce_cs_parse()
On the off chance that command stream passed from userspace via
ioctl() call to radeon_vce_cs_parse() is weirdly crafted and
first command to execute is to encode (case 0x03000001), the function
in question will attempt to call radeon_vce_cs_reloc() with size
argument that has not been properly initialized. Specifically, 'size'
will point to 'tmp' variable before the latter had a chance to be
assigned any value.
Play it safe and init 'tmp' with 0, thus ensuring that
radeon_vce_cs_reloc() will catch an early error in cases like these.
Found by Linux Verification Center (linuxtesting.org) with static
analysis tool SVACE.
(cherry picked from commit 2d52de55f9ee7aaee0e09ac443f77855989c6b68)

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_event: Ignore multiple conn complete events
When one of the three connection complete events is received multiple
times for the same handle, the device is registered multiple times which
leads to memory corruptions. Therefore, consequent events for a single
connection are ignored.
The conn->state can hold different values, therefore HCI_CONN_HANDLE_UNSET
is introduced to identify new connections. To make sure the events do not
contain this or another invalid handle HCI_CONN_HANDLE_MAX and checks
are introduced.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ARM: meson: Fix refcount leak in meson_smp_prepare_cpus
of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: ibmvfc: Allocate/free queue resource only during probe/remove
Currently, the sub-queues and event pool resources are allocated/freed for
every CRQ connection event such as reset and LPM. This exposes the driver
to a couple issues. First the inefficiency of freeing and reallocating
memory that can simply be resued after being sanitized. Further, a system
under memory pressue runs the risk of allocation failures that could result
in a crippled driver. Finally, there is a race window where command
submission/compeletion can try to pull/return elements from/to an event
pool that is being deleted or already has been deleted due to the lack of
host state around freeing/allocating resources. The following is an example
of list corruption following a live partition migration (LPM):

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvdimm: Fix firmware activation deadlock scenarios
Lockdep reports the following deadlock scenarios for CXL root device
power-management, device_prepare(), operations, and device_shutdown()
operations for 'nd_region' devices:
Chain exists of:
&nvdimm_region_key --> &nvdimm_bus->reconfig_mutex --> system_transition_mutex
Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock(system_transition_mutex);
lock(&nvdimm_bus->reconfig_mutex);
lock(system_transition_mutex);
lock(&nvdimm_region_key);
Chain exists of:
&cxl_nvdimm_bridge_key --> acpi_scan_lock --> &cxl_root_key
Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock(&cxl_root_key);
lock(acpi_scan_lock);
lock(&cxl_root_key);
lock(&cxl_nvdimm_bridge_key);
These stem from holding nvdimm_bus_lock() over hibernate_quiet_exec()
which walks the entire system device topology taking device_lock() along
the way. The nvdimm_bus_lock() is protecting against unregistration,
multiple simultaneous ops callers, and preventing activate_show() from
racing activate_store(). For the first 2, the lock is redundant.
Unregistration already flushes all ops users, and sysfs already prevents
multiple threads to be active in an ops handler at the same time. For
the last userspace should already be waiting for its last
activate_store() to complete, and does not need activate_show() to flush
the write side, so this lock usage can be deleted in these attributes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: add accessors to read/set tp->snd_cwnd
We had various bugs over the years with code
breaking the assumption that tp->snd_cwnd is greater
than zero.
Lately, syzbot reported the WARN_ON_ONCE(!tp->prior_cwnd) added
in commit 8b8a321ff72c ("tcp: fix zero cwnd in tcp_cwnd_reduction")
can trigger, and without a repro we would have to spend
considerable time finding the bug.
Instead of complaining too late, we want to catch where
and when tp->snd_cwnd is set to an illegal value.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drbd: Fix five use after free bugs in get_initial_state
In get_initial_state, it calls notify_initial_state_done(skb,..) if
cb->args[5]==1. If genlmsg_put() failed in notify_initial_state_done(),
the skb will be freed by nlmsg_free(skb).
Then get_initial_state will goto out and the freed skb will be used by
return value skb->len, which is a uaf bug.
What's worse, the same problem goes even further: skb can also be
freed in the notify_*_state_change -> notify_*_state calls below.
Thus 4 additional uaf bugs happened.
My patch lets the problem callee functions: notify_initial_state_done
and notify_*_state_change return an error code if errors happen.
So that the error codes could be propagated and the uaf bugs can be avoid.
v2 reports a compilation warning. This v3 fixed this warning and built
successfully in my local environment with no additional warnings.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: staging: media: zoran: calculate the right buffer number for zoran_reap_stat_com
On the case tmp_dcim=1, the index of buffer is miscalculated.
This generate a NULL pointer dereference later.
So let's fix the calcul and add a check to prevent this to reappear.

One way to trigger this is:
1. load a livepatch that patches kernel function xxx;
2. run bpftrace -e 'kfunc:xxx {}', this will fail (expected for now);
3. repeat #2 => gpf.
This is because the entry is added to direct_functions, but not removed.
Fix this by remove the entry from direct_functions when
register_ftrace_direct fails.
Also remove the last trailing space from ftrace.c, so we don't have to
worry about it anymore.

Summary
In the Linux kernel, the following vulnerability has been resolved:
udp: fix race between close() and udp_abort()
Kaustubh reported and diagnosed a panic in udp_lib_lookup().
The root cause is udp_abort() racing with close(). Both
racing functions acquire the socket lock, but udp{v6}_destroy_sock()
release it before performing destructive actions.
We can't easily extend the socket lock scope to avoid the race,
instead use the SOCK_DEAD flag to prevent udp_abort from doing
any action when the critical race happens.
Diagnosed-and-tested-by: Kaustubh Pandey <kapandey@codeaurora.org>

Summary
In the Linux kernel, the following vulnerability has been resolved:
ata: libata-core: fix NULL pointer deref in ata_host_alloc_pinfo()
In an unlikely (and probably wrong?) case that the 'ppi' parameter of
ata_host_alloc_pinfo() points to an array starting with a NULL pointer,
there's going to be a kernel oops as the 'pi' local variable won't get
reassigned from the initial value of NULL. Initialize 'pi' instead to
'&ata_dummy_port_info' to fix the possible kernel oops for good...
Found by Linux Verification Center (linuxtesting.org) with the SVACE static
analysis tool.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86/mmu: Zap _all_ roots when unmapping gfn range in TDP MMU
Zap both valid and invalid roots when zapping/unmapping a gfn range, as
KVM must ensure it holds no references to the freed page after returning
from the unmap operation. Most notably, the TDP MMU doesn't zap invalid
roots in mmu_notifier callbacks. This leads to use-after-free and other
issues if the mmu_notifier runs to completion while an invalid root
zapper yields as KVM fails to honor the requirement that there must be
_no_ references to the page after the mmu_notifier returns.
The bug is most easily reproduced by hacking KVM to cause a collision
between set_nx_huge_pages() and kvm_mmu_notifier_release(), but the bug
exists between kvm_mmu_notifier_invalidate_range_start() and memslot
updates as well. Invalidating a root ensures pages aren't accessible by
the guest, and KVM won't read or write page data itself, but KVM will
trigger e.g. kvm_set_pfn_dirty() when zapping SPTEs, and thus completing
a zap of an invalid root _after_ the mmu_notifier returns is fatal.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/arm-smmu-v3-sva: Fix mm use-after-free
We currently call arm64_mm_context_put() without holding a reference to
the mm, which can result in use-after-free. Call mmgrab()/mmdrop() to
ensure the mm only gets freed after we unpinned the ASID.

The Oops happens because the I2C client data does not point to
max9286_priv anymore but to v4l2_subdev. The change happened in
max9286_init() which calls v4l2_i2c_subdev_init() later on...
Besides fixing the max9286_remove() function, remove the call to
i2c_set_clientdata() in max9286_probe(), to avoid confusion, and make
the necessary changes to max9286_init() so that it doesn't have to use
i2c_get_clientdata() in order to fetch the pointer to priv.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: Fix signed integer overflow in l2tp_ip6_sendmsg
When len >= INT_MAX - transhdrlen, ulen = len + transhdrlen will be
overflow. To fix, we can follow what udpv6 does and subtract the
transhdrlen from the max.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: atmel: Fix error handling in snd_proto_probe
The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
This function only calls of_node_put() in the regular path.
And it will cause refcount leak in error paths.
Fix this by calling of_node_put() in error handling too.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tty: goldfish: Use tty_port_destroy() to destroy port
In goldfish_tty_probe(), the port initialized through tty_port_init()
should be destroyed in error paths.In goldfish_tty_remove(), qtty->port
also should be destroyed or else might leak resources.
Fix the above by calling tty_port_destroy().

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: ti-vpe: cal: Fix a NULL pointer dereference in cal_ctx_v4l2_init_formats()
In cal_ctx_v4l2_init_formats(), devm_kzalloc() is assigned to
ctx->active_fmt and there is a dereference of it after that, which could
lead to NULL pointer dereference on failure of devm_kzalloc().
Fix this bug by adding a NULL check of ctx->active_fmt.
This bug was found by a static analyzer.
Builds with 'make allyesconfig' show no new warnings, and our static
analyzer no longer warns about this code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
macsec: fix UAF bug for real_dev
Create a new macsec device but not get reference to real_dev. That can
not ensure that real_dev is freed after macsec. That will trigger the
UAF bug for real_dev as following:

After commit faab39f63c1f ("net: allow out-of-order netdev unregistration")
and commit e5f80fcf869a ("ipv6: give an IPv6 dev to blackhole_netdev"), we
can add dev_hold_track() in macsec_dev_init() and dev_put_track() in
macsec_free_netdev() to fix the problem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: oss: Fix PCM OSS buffer allocation overflow
We've got syzbot reports hitting INT_MAX overflow at vmalloc()
allocation that is called from snd_pcm_plug_alloc(). Although we
apply the restrictions to input parameters, it's based only on the
hw_params of the underlying PCM device. Since the PCM OSS layer
allocates a temporary buffer for the data conversion, the size may
become unexpectedly large when more channels or higher rates is given;
in the reported case, it went over INT_MAX, hence it hits WARN_ON().
This patch is an attempt to avoid such an overflow and an allocation
for too large buffers. First off, it adds the limit of 1MB as the
upper bound for period bytes. This must be large enough for all use
cases, and we really don't want to handle a larger temporary buffer
than this size. The size check is performed at two places, where the
original period bytes is calculated and where the plugin buffer size
is calculated.
In addition, the driver uses array_size() and array3_size() for
multiplications to catch overflows for the converted period size and
buffer bytes.

Although we\napply the restrictions to input parameters, it\u0027s based only on the\nhw_params of the underlying PCM device. Since the PCM OSS layer\nallocates a temporary buffer for the data conversion, the size may\nbecome unexpectedly large when more channels or higher rates is given;\nin the reported case, it went over INT_MAX, hence it hits WARN_ON().\n\nThis patch is an attempt to avoid such an overflow and an allocation\nfor too large buffers. First off, it adds the limit of 1MB as the\nupper bound for period bytes. This must be large enough for all use\ncases, and we really don\u0027t want to handle a larger temporary buffer\nthan this size. The size check is performed at two places, where the\noriginal period bytes is calculated and where the plugin buffer size\nis calculated.\n\nIn addition, the driver uses array_size() and array3_size() for\nmultiplications to catch overflows for the converted period size and\nbuffer bytes."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: fix LGR and link use-after-free issue
We encountered a LGR/link use-after-free issue, which manifested as
the LGR/link refcnt reaching 0 early and entering the clear process,
making resource access unsafe.
refcount_t: addition on 0; use-after-free.
WARNING: CPU: 14 PID: 107447 at lib/refcount.c:25 refcount_warn_saturate+0x9c/0x140

Call trace:

process_one_work+0x1b8/0x420
worker_thread+0x158/0x510
kthread+0x114/0x118
It is caused by repeated release of LGR/link refcnt. One suspect is that
smc_conn_free() is called repeatedly because some smc_conn_free() from
server listening path are not protected by sock lock.
e.g.
Calls under socklock | smc_listen_work
-------------------------------------------------------
lock_sock(sk) | smc_conn_abort
smc_conn_free | \- smc_conn_free
\- smcr_link_put | \- smcr_link_put (duplicated)
release_sock(sk)
So here add sock lock protection in smc_listen_work() path, making it
exclusive with other connection operations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix scheduling while atomic
The driver makes a call into midlayer (fc_remote_port_delete) which can put
the thread to sleep. The thread that originates the call is in interrupt
context. The combination of the two trigger a crash. Schedule the call in
non-interrupt context where it is more safe.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bfq: Make sure bfqg for which we are queueing requests is online
Bios queued into BFQ IO scheduler can be associated with a cgroup that
was already offlined. This may then cause insertion of this bfq_group
into a service tree. But this bfq_group will get freed as soon as last
bio associated with it is completed leading to use after free issues for
service tree users. Fix the problem by making sure we always operate on
online bfq_group. If the bfq_group associated with the bio is not
online, we pick the first online parent.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Fix memleak in sk_psock_queue_msg
If tcp_bpf_sendmsg is running during a tear down operation we may enqueue
data on the ingress msg queue while tear down is trying to free it.
sk1 (redirect sk2) sk2
------------------- ---------------
tcp_bpf_sendmsg()
tcp_bpf_send_verdict()
tcp_bpf_sendmsg_redir()
bpf_tcp_ingress()
sock_map_close()
lock_sock()
lock_sock() ... blocking
sk_psock_stop
sk_psock_clear_state(psock, SK_PSOCK_TX_ENABLED);
release_sock(sk);
lock_sock()
sk_mem_charge()
get_page()
sk_psock_queue_msg()
sk_psock_test_state(psock, SK_PSOCK_TX_ENABLED);
drop_sk_msg()
release_sock()
While drop_sk_msg(), the msg has charged memory form sk by sk_mem_charge
and has sg pages need to put. To fix we use sk_msg_free() and then kfee()
msg.
This issue can cause the following info:

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: isotp: sanitize CAN ID checks in isotp_bind()
Syzbot created an environment that lead to a state machine status that
can not be reached with a compliant CAN ID address configuration.
The provided address information consisted of CAN ID 0x6000001 and 0xC28001
which both boil down to 11 bit CAN IDs 0x001 in sending and receiving.
Sanitize the SFF/EFF CAN ID values before performing the address checks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
driver core: fix deadlock in __device_attach
In __device_attach function, The lock holding logic is as follows:
...
__device_attach
device_lock(dev) // get lock dev
async_schedule_dev(__device_attach_async_helper, dev); // func
async_schedule_node
async_schedule_node_domain(func)
entry = kzalloc(sizeof(struct async_entry), GFP_ATOMIC);
/* when fail or work limit, sync to execute func, but
__device_attach_async_helper will get lock dev as
well, which will lead to A-A deadlock. */
if (!entry || atomic_read(&entry_count) > MAX_WORK) {
func;
else
queue_work_node(node, system_unbound_wq, &entry->work)
device_unlock(dev)
As shown above, when it is allowed to do async probes, because of
out of memory or work limit, async work is not allowed, to do
sync execute instead. it will lead to A-A deadlock because of
__device_attach_async_helper getting lock dev.
To fix the deadlock, move the async_schedule_dev outside device_lock,
as we can see, in async_schedule_node_domain, the parameter of
queue_work_node is system_unbound_wq, so it can accept concurrent
operations. which will also not change the code logic, and will
not lead to deadlock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfc: nci: add flush_workqueue to prevent uaf
Our detector found a concurrent use-after-free bug when detaching an
NCI device. The main reason for this bug is the unexpected scheduling
between the used delayed mechanism (timer and workqueue).
The race can be demonstrated below:
Thread-1 Thread-2
| nci_dev_up()
| nci_open_device()
| __nci_request(nci_reset_req)
| nci_send_cmd
| queue_work(cmd_work)
nci_unregister_device() |
nci_close_device() | ...
del_timer_sync(cmd_timer)[1] |
... | Worker
nci_free_device() | nci_cmd_work()
kfree(ndev)[3] | mod_timer(cmd_timer)[2]
In short, the cleanup routine thought that the cmd_timer has already
been detached by [1] but the mod_timer can re-attach the timer [2], even
it is already released [3], resulting in UAF.
This UAF is easy to trigger, crash trace by POC is like below

Summary
In the Linux kernel, the following vulnerability has been resolved:
exfat: check if cluster num is valid
Syzbot reported slab-out-of-bounds read in exfat_clear_bitmap.
This was triggered by reproducer calling truncute with size 0,
which causes the following trace:
BUG: KASAN: slab-out-of-bounds in exfat_clear_bitmap+0x147/0x490 fs/exfat/balloc.c:174

Move the is_valid_cluster() helper from fatent.c to a common
header to make it reusable in other *.c files. And add is_valid_cluster()
to validate if cluster number is within valid range in exfat_clear_bitmap()
and exfat_set_bitmap().

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: isp1760: Fix out-of-bounds array access
Running the driver through kasan gives an interesting splat:
BUG: KASAN: global-out-of-bounds in isp1760_register+0x180/0x70c
Read of size 20 at addr f1db2e64 by task swapper/0/1
(...)
isp1760_register from isp1760_plat_probe+0x1d8/0x220
(...)
This happens because the loop reading the regmap fields for the
different ISP1760 variants look like this:
for (i = 0; i < HC_FIELD_MAX; i++) { ... }
Meaning it expects the arrays to be at least HC_FIELD_MAX - 1 long.
However the arrays isp1760_hc_reg_fields[], isp1763_hc_reg_fields[],
isp1763_hc_volatile_ranges[] and isp1763_dc_volatile_ranges[] are
dynamically sized during compilation.
Fix this by putting an empty assignment to the [HC_FIELD_MAX]
and [DC_FIELD_MAX] array member at the end of each array.
This will make the array one member longer than it needs to be,
but avoids the risk of overwriting whatever is inside
[HC_FIELD_MAX - 1] and is simple and intuitive to read. Also
add comments explaining what is going on.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: hisi_sas: Free irq vectors in order for v3 HW
If the driver probe fails to request the channel IRQ or fatal IRQ, the
driver will free the IRQ vectors before freeing the IRQs in free_irq(),
and this will cause a kernel BUG like this:
------------[ cut here ]------------
kernel BUG at drivers/pci/msi.c:369!
Internal error: Oops - BUG: 0 [#1] PREEMPT SMP
Call trace:
free_msi_irqs+0x118/0x13c
pci_disable_msi+0xfc/0x120

---[ end trace b88990335b610c11 ]---
So we use devm_add_action() to control the order in which we free the
vectors.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: pm8001: Fix tag leaks on error
In pm8001_chip_set_dev_state_req(), pm8001_chip_fw_flash_update_req(),
pm80xx_chip_phy_ctl_req() and pm8001_chip_reg_dev_req() add missing calls
to pm8001_tag_free() to free the allocated tag when pm8001_mpi_build_cmd()
fails.
Similarly, in pm8001_exec_internal_task_abort(), if the chip ->task_abort
method fails, the tag allocated for the abort request task must be
freed. Add the missing call to pm8001_tag_free().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: wcd934x: Add missing of_node_put() in wcd934x_codec_parse_data
The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
This is similar to commit 64b92de9603f
("ASoC: wcd9335: fix a leaked reference by adding missing of_node_put")

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Move cfg_log_verbose check before calling lpfc_dmp_dbg()
In an attempt to log message 0126 with LOG_TRACE_EVENT, the following hard
lockup call trace hangs the system.
Call Trace:
_raw_spin_lock_irqsave+0x32/0x40
lpfc_dmp_dbg.part.32+0x28/0x220 [lpfc]
lpfc_cmpl_els_fdisc+0x145/0x460 [lpfc]
lpfc_sli_cancel_jobs+0x92/0xd0 [lpfc]
lpfc_els_flush_cmd+0x43c/0x670 [lpfc]
lpfc_els_flush_all_cmd+0x37/0x60 [lpfc]
lpfc_sli4_async_event_proc+0x956/0x1720 [lpfc]
lpfc_do_work+0x1485/0x1d70 [lpfc]
kthread+0x112/0x130
ret_from_fork+0x1f/0x40
Kernel panic - not syncing: Hard LOCKUP
The same CPU tries to claim the phba->port_list_lock twice.
Move the cfg_log_verbose checks as part of the lpfc_printf_vlog() and
lpfc_printf_log() macros before calling lpfc_dmp_dbg(). There is no need
to take the phba->port_list_lock within lpfc_dmp_dbg().
