Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Fix use-after-free bugs caused by sco_sock_timeout
When the sco connection is established and then, the sco socket
is releasing, timeout_work will be scheduled to judge whether
the sco disconnection is timeout. The sock will be deallocated
later, but it is dereferenced again in sco_sock_timeout. As a
result, the use-after-free bugs will happen. The root cause is
shown below:
Cleanup Thread | Worker Thread
sco_sock_release |
sco_sock_close |
__sco_sock_close |
sco_sock_set_timer |
schedule_delayed_work |
sco_sock_kill | (wait a time)
sock_put(sk) //FREE | sco_sock_timeout
| sock_hold(sk) //USE
The KASAN report triggered by POC is shown below:

Summary
In the Linux kernel, the following vulnerability has been resolved:
tomoyo: fix UAF write bug in tomoyo_write_control()
Since tomoyo_write_control() updates head->write_buf when write()
of long lines is requested, we need to fetch head->write_buf after
head->io_sem is held. Otherwise, concurrent write() requests can
cause use-after-free-write and double-free problems.

Summary
In the Linux kernel, the following vulnerability has been resolved:
hsr: Prevent use after free in prp_create_tagged_frame()
The prp_fill_rct() function can fail. In that situation, it frees the
skb and returns NULL. Meanwhile on the success path, it returns the
original skb. So it's straight forward to fix bug by using the returned
value.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: fix a memory corruption
iwl_fw_ini_trigger_tlv::data is a pointer to a __le32, which means that
if we copy to iwl_fw_ini_trigger_tlv::data + offset while offset is in
bytes, we'll write past the buffer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/hfi1: Fix sdma.h tx->num_descs off-by-one error
Unfortunately the commit `fd8958efe877` introduced another error
causing the `descs` array to overflow. This reults in further crashes
easily reproducible by `sendmsg` system call.

}
If an SDMA send consists of exactly 6 descriptors and requires dword
padding (in the 7th descriptor), the sdma_txreq descriptor array is not
properly expanded and the packet will overflow into the container
structure. This results in a panic when the send completion runs. The
exact panic varies depending on what elements of the container structure
get corrupted. The fix is to use the correct expression in
_pad_sdma_tx_descs() to test the need to expand the descriptor array.
With this patch the crashes are no longer reproducible and the machine is
stable.

Summary
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Fix garbage collector racing against connect()
Garbage collector does not take into account the risk of embryo getting
enqueued during the garbage collection. If such embryo has a peer that
carries SCM_RIGHTS, two consecutive passes of scan_children() may see a
different set of children. Leading to an incorrectly elevated inflight
count, and then a dangling pointer within the gc_inflight_list.
sockets are AF_UNIX/SOCK_STREAM
S is an unconnected socket
L is a listening in-flight socket bound to addr, not in fdtable
V's fd will be passed via sendmsg(), gets inflight count bumped
connect(S, addr) sendmsg(S, [V]); close(V) __unix_gc()
---------------- ------------------------- -----------
NS = unix_create1()
skb1 = sock_wmalloc(NS)
L = unix_find_other(addr)
unix_state_lock(L)
unix_peer(S) = NS
// V count=1 inflight=0
NS = unix_peer(S)
skb2 = sock_alloc()
skb_queue_tail(NS, skb2[V])
// V became in-flight
// V count=2 inflight=1
close(V)
// V count=1 inflight=1
// GC candidate condition met
for u in gc_inflight_list:
if (total_refs == inflight_refs)
add u to gc_candidates
// gc_candidates={L, V}
for u in gc_candidates:
scan_children(u, dec_inflight)
// embryo (skb1) was not
// reachable from L yet, so V's
// inflight remains unchanged
__skb_queue_tail(L, skb1)
unix_state_unlock(L)
for u in gc_candidates:
if (u.inflight)
scan_children(u, inc_inflight_move_tail)
// V count=1 inflight=2 (!)
If there is a GC-candidate listening socket, lock/unlock its state. This
makes GC wait until the end of any ongoing connect() to that socket. After
flipping the lock, a possibly SCM-laden embryo is already enqueued. And if
there is another embryo coming, it can not possibly carry SCM_RIGHTS. At
this point, unix_inflight() can not happen because unix_gc_lock is already
taken. Inflight graph remains unaffected.

Summary
A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This could allow a local unprivileged user to escalate their privileges on the system.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix a potential use-after-free in bpf_link_free()
After commit 1a80dbcb2dba, bpf_link can be freed by
link->ops->dealloc_deferred, but the code still tests and uses
link->ops->dealloc afterward, which leads to a use-after-free as
reported by syzbot. Actually, one of them should be sufficient, so
just call one of them instead of both. Also add a WARN_ON() in case
of any problematic implementation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: nfc: fix races in nfc_llcp_sock_get() and nfc_llcp_sock_get_sn()
Sili Luo reported a race in nfc_llcp_sock_get(), leading to UAF.
Getting a reference on the socket found in a lookup while
holding a lock should happen before releasing the lock.
nfc_llcp_sock_get_sn() has a similar problem.
Finally nfc_llcp_recv_snl() needs to make sure the socket
found by nfc_llcp_sock_from_sn() does not disappear.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Protect against int overflow for stack access size
This patch re-introduces protection against the size of access to stack
memory being negative; the access size can appear negative as a result
of overflowing its signed int representation. This should not actually
happen, as there are other protections along the way, but we should
protect against it anyway. One code path was missing such protections
(fixed in the previous patch in the series), causing out-of-bounds array
accesses in check_stack_range_initialized(). This patch causes the
verification of a program with such a non-sensical access size to fail.
This check used to exist in a more indirect way, but was inadvertendly
removed in a833a17aeac7.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: make sure that WRITTEN is set on all metadata blocks
We previously would call btrfs_check_leaf() if we had the check
integrity code enabled, which meant that we could only run the extended
leaf checks if we had WRITTEN set on the header flags.
This leaves a gap in our checking, because we could end up with
corruption on disk where WRITTEN isn't set on the leaf, and then the
extended leaf checks don't get run which we rely on to validate all of
the item pointers to make sure we don't access memory outside of the
extent buffer.
However, since 732fab95abe2 ("btrfs: check-integrity: remove
CONFIG_BTRFS_FS_CHECK_INTEGRITY option") we no longer call
btrfs_check_leaf() from btrfs_mark_buffer_dirty(), which means we only
ever call it on blocks that are being written out, and thus have WRITTEN
set, or that are being read in, which should have WRITTEN set.
Add checks to make sure we have WRITTEN set appropriately, and then make
sure __btrfs_check_leaf() always does the item checking. This will
protect us from file systems that have been corrupted and no longer have
WRITTEN set on some of the blocks.
This was hit on a crafted image tweaking the WRITTEN bit and reported by
KASAN as out-of-bound access in the eb accessors. The example is a dir
item at the end of an eb.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: make sure that WRITTEN is set on all metadata blocks\n\nWe previously would call btrfs_check_leaf() if we had the check\nintegrity code enabled, which meant that we could only run the extended\nleaf checks if we had WRITTEN set on the header flags.\n\nThis leaves a gap in our checking, because we could end up with\ncorruption on disk where WRITTEN isn\u0027t set on the leaf, and then the\nextended leaf checks don\u0027t get run which we rely on to validate all of\nthe item pointers to make sure we don\u0027t access memory outside of the\nextent buffer.\n\nHowever, since 732fab95abe2 (\"btrfs: check-integrity: remove\nCONFIG_BTRFS_FS_CHECK_INTEGRITY option\") we no longer call\nbtrfs_check_leaf() from btrfs_mark_buffer_dirty(), which means we only\never call it on blocks that are being written out, and thus have WRITTEN\nset, or that are being read in, which should have WRITTEN set.\n\nAdd checks to make sure we have WRITTEN set appropriately, and then make\nsure __btrfs_check_leaf() always does the item checking. This will\nprotect us from file systems that have been corrupted and no longer have\nWRITTEN set on some of the blocks.\n\nThis was hit on a crafted image tweaking the WRITTEN bit and reported by\nKASAN as out-of-bound access in the eb accessors.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: do not leave a dangling sk pointer, when socket creation fails
It is possible to trigger a use-after-free by:
* attaching an fentry probe to __sock_release() and the probe calling the
bpf_get_socket_cookie() helper
* running traceroute -I 1.1.1.1 on a freshly booted VM
A KASAN enabled kernel will log something like below (decoded and stripped):
==================================================================

Summary
In the Linux kernel, the following vulnerability has been resolved:
tty: Fix out-of-bound vmalloc access in imageblit
This issue happens when a userspace program does an ioctl
FBIOPUT_VSCREENINFO passing the fb_var_screeninfo struct
containing only the fields xres, yres, and bits_per_pixel
with values.
If this struct is the same as the previous ioctl, the
vc_resize() detects it and doesn't call the resize_screen(),
leaving the fb_var_screeninfo incomplete. And this leads to
the updatescrollmode() calculates a wrong value to
fbcon_display->vrows, which makes the real_y() return a
wrong value of y, and that value, eventually, causes
the imageblit to access an out-of-bound address value.
To solve this issue I made the resize_screen() be called
even if the screen does not need any resizing, so it will
"fix and fill" the fb_var_screeninfo independently.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: Use refcount_inc_not_zero() in tcp_twsk_unique().
Anderson Nascimento reported a use-after-free splat in tcp_twsk_unique()
with nice analysis.
Since commit ec94c2696f0b ("tcp/dccp: avoid one atomic operation for
timewait hashdance"), inet_twsk_hashdance() sets TIME-WAIT socket's
sk_refcnt after putting it into ehash and releasing the bucket lock.
Thus, there is a small race window where other threads could try to
reuse the port during connect() and call sock_hold() in tcp_twsk_unique()
for the TIME-WAIT socket with zero refcnt.
If that happens, the refcnt taken by tcp_twsk_unique() is overwritten
and sock_put() will cause underflow, triggering a real use-after-free
somewhere else.
To avoid the use-after-free, we need to use refcount_inc_not_zero() in
tcp_twsk_unique() and give up on reusing the port if it returns false.
[0]:
refcount_t: addition on 0; use-after-free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/ipv6: avoid possible UAF in ip6_route_mpath_notify()
syzbot found another use-after-free in ip6_route_mpath_notify() [1]
Commit f7225172f25a ("net/ipv6: prevent use after free in
ip6_route_mpath_notify") was not able to fix the root cause.
We need to defer the fib6_info_release() calls after
ip6_route_mpath_notify(), in the cleanup phase.

addr ffff888112fc713c is located in stack of task handler2/1367 at offset 180 in frame:

for IPv4 packets, ovs_fragment() uses a temporary struct dst_entry. Then,
in the following call graph:
ip_do_fragment()
ip_skb_dst_mtu()
ip_dst_mtu_maybe_forward()
ip_mtu_locked()
the pointer to struct dst_entry is used as pointer to struct rtable: this
turns the access to struct members like rt_mtu_locked into an OOB read in
the stack. Fix this changing the temporary variable used for IPv4 packets
in ovs_fragment(), similarly to what is done for IPv6 few lines below.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipvlan: Fix out-of-bound bugs caused by unset skb->mac_header
If an AF_PACKET socket is used to send packets through ipvlan and the
default xmit function of the AF_PACKET socket is changed from
dev_queue_xmit() to packet_direct_xmit() via setsockopt() with the option
name of PACKET_QDISC_BYPASS, the skb->mac_header may not be reset and
remains as the initial value of 65535, this may trigger slab-out-of-bounds
bugs as following:
=================================================================
UG: KASAN: slab-out-of-bounds in ipvlan_xmit_mode_l2+0xdb/0x330 [ipvlan]
PU: 2 PID: 1768 Comm: raw_send Kdump: loaded Not tainted 6.0.0-rc4+ #6
ardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc33
all Trace:

print_report.cold+0x4f/0x112
kasan_report+0xa3/0x130

__x64_sys_sendto+0x74/0x90
do_syscall_64+0x3b/0x90
entry_SYSCALL_64_after_hwframe+0x63/0xcd
The root cause is:
1. packet_snd() only reset skb->mac_header when sock->type is SOCK_RAW
and skb->protocol is not specified as in packet_parse_headers()
2. packet_direct_xmit() doesn't reset skb->mac_header as dev_queue_xmit()
In this case, skb->mac_header is 65535 when ipvlan_xmit_mode_l2() is
called. So when ipvlan_xmit_mode_l2() gets mac header with eth_hdr() which
use "skb->head + skb->mac_header", out-of-bound access occurs.
This patch replaces eth_hdr() with skb_eth_hdr() in ipvlan_xmit_mode_l2()
and reset mac header in multicast to solve this out-of-bound bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/9p: only translate RWX permissions for plain 9P2000
Garbage in plain 9P2000's perm bits is allowed through, which causes it
to be able to set (among others) the suid bit. This was presumably not
the intent since the unix extended bits are handled explicitly and
conditionally on .u.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: fix race between tx work scheduling and socket close
Similarly to previous commit, the submitting thread (recvmsg/sendmsg)
may exit as soon as the async crypto handler calls complete().
Reorder scheduling the work before calling complete().
This seems more logical in the first place, as it's
the inverse order of what the submitting thread will do.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: amdgpu_ttm_gart_bind set gtt bound flag
Otherwise after the GTT bo is released, the GTT and gart space is freed
but amdgpu_ttm_backend_unbind will not clear the gart page table entry
and leave valid mapping entry pointing to the stale system page. Then
if GPU access the gart address mistakely, it will read undefined value
instead page fault, harder to debug and reproduce the real issue.

CWE
- CWE-416 - Use After Free
Summary
A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate filters in case of a perfect hashes while deleting the underlying structure which can later lead to double freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root.
We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gpiolib: cdev: Fix use after free in lineinfo_changed_notify
The use-after-free issue occurs as follows: when the GPIO chip device file
is being closed by invoking gpio_chrdev_release(), watched_lines is freed
by bitmap_free(), but the unregistration of lineinfo_changed_nb notifier
chain failed due to waiting write rwsem. Additionally, one of the GPIO
chip's lines is also in the release process and holds the notifier chain's
read rwsem. Consequently, a race condition leads to the use-after-free of
watched_lines.
Here is the typical stack when issue happened:
[free]
gpio_chrdev_release()
--> bitmap_free(cdev->watched_lines) <-- freed
--> blocking_notifier_chain_unregister()
--> down_write(&nh->rwsem) <-- waiting rwsem
--> __down_write_common()
--> rwsem_down_write_slowpath()
--> schedule_preempt_disabled()
--> schedule()
[use]
st54spi_gpio_dev_release()
--> gpio_free()
--> gpiod_free()
--> gpiod_free_commit()
--> gpiod_line_state_notify()
--> blocking_notifier_call_chain()
--> down_read(&nh->rwsem); <-- held rwsem
--> notifier_call_chain()
--> lineinfo_changed_notify()
--> test_bit(xxxx, cdev->watched_lines) <-- use after free
The side effect of the use-after-free issue is that a GPIO line event is
being generated for userspace where it shouldn't. However, since the chrdev
is being closed, userspace won't have the chance to read that event anyway.
To fix the issue, call the bitmap_free() function after the unregistration
of lineinfo_changed_nb notifier chain.

Consequently, a race condition leads to the use-after-free of\nwatched_lines.\n\nHere is the typical stack when issue happened:\n\n[free]\ngpio_chrdev_release()\n --\u003e bitmap_free(cdev-\u003ewatched_lines) \u003c-- freed\n --\u003e blocking_notifier_chain_unregister()\n --\u003e down_write(\u0026nh-\u003erwsem) \u003c-- waiting rwsem\n --\u003e __down_write_common()\n --\u003e rwsem_down_write_slowpath()\n --\u003e schedule_preempt_disabled()\n --\u003e schedule()\n\n[use]\nst54spi_gpio_dev_release()\n --\u003e gpio_free()\n --\u003e gpiod_free()\n --\u003e gpiod_free_commit()\n --\u003e gpiod_line_state_notify()\n --\u003e blocking_notifier_call_chain()\n --\u003e down_read(\u0026nh-\u003erwsem); \u003c-- held rwsem\n --\u003e notifier_call_chain()\n --\u003e lineinfo_changed_notify()\n --\u003e test_bit(xxxx, cdev-\u003ewatched_lines) \u003c-- use after free\n\nThe side effect of the use-after-free issue is that a GPIO line event is\nbeing generated for userspace where it shouldn\u0027t.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gem: Really move i915_gem_context.link under ref protection
i915_perf assumes that it can use the i915_gem_context reference to
protect its i915->gem.contexts.list iteration. However, this requires
that we do not remove the context from the list until after we drop the
final reference and release the struct. If, as currently, we remove the
context from the list during context_close(), the link.next pointer may
be poisoned while we are holding the context reference and cause a GPF:

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: fix underflow in parse_server_interfaces()
In this loop, we step through the buffer and after each item we check
if the size_left is greater than the minimum size we need. However,
the problem is that "bytes_left" is type ssize_t while sizeof() is type
size_t. That means that because of type promotion, the comparison is
done as an unsigned and if we have negative bytes left the loop
continues instead of ending.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/client: Fully protect modes[] with dev->mode_config.mutex
The modes[] array contains pointers to modes on the connectors'
mode lists, which are protected by dev->mode_config.mutex.
Thus we need to extend modes[] the same protection or by the
time we use it the elements may already be pointing to
freed/reused memory.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sched: flower: protect fl_walk() with rcu
Patch that refactored fl_walk() to use idr_for_each_entry_continue_ul()
also removed rcu protection of individual filters which causes following
use-after-free when filter is deleted concurrently. Fix fl_walk() to obtain
rcu read lock while iterating and taking the filter reference and temporary
release the lock while calling arg->fn() callback that can sleep.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-rdma: destroy cm id before destroy qp to avoid use after free
We should always destroy cm_id before destroy qp to avoid to get cma
event after qp was destroyed, which may lead to use after free.
In RDMA connection establishment error flow, don't destroy qp in cm
event handler.Just report cm_error to upper level, qp will be destroy
in nvme_rdma_alloc_queue() after destroy cm id.

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:
ipv6: fix another slab-out-of-bounds in fib6_nh_flush_exceptions
While running the self-tests on a KASAN enabled kernel, I observed a
slab-out-of-bounds splat very similar to the one reported in
commit 821bbf79fe46 ("ipv6: Fix KASAN: slab-out-of-bounds Read in
fib6_nh_flush_exceptions").
We additionally need to take care of fib6_metrics initialization
failure when the caller provides an nh.
The fix is similar, explicitly free the route instead of calling
fib6_info_release on a half-initialized object.
