Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix race between transaction aborts and fsyncs leading to use-after-free
There is a race between a task aborting a transaction during a commit,
a task doing an fsync and the transaction kthread, which leads to an
use-after-free of the log root tree. When this happens, it results in a
stack trace like the following:
BTRFS info (device dm-0): forced readonly
BTRFS warning (device dm-0): Skipping commit of aborted transaction.
BTRFS: error (device dm-0) in cleanup_transaction:1958: errno=-5 IO failure
BTRFS warning (device dm-0): lost page write due to IO error on /dev/mapper/error-test (-5)
BTRFS warning (device dm-0): Skipping commit of aborted transaction.
BTRFS warning (device dm-0): direct IO failed ino 261 rw 0,0 sector 0xa4e8 len 4096 err no 10
BTRFS error (device dm-0): error writing primary super block to device 1
BTRFS warning (device dm-0): direct IO failed ino 261 rw 0,0 sector 0x12e000 len 4096 err no 10
BTRFS warning (device dm-0): direct IO failed ino 261 rw 0,0 sector 0x12e008 len 4096 err no 10
BTRFS warning (device dm-0): direct IO failed ino 261 rw 0,0 sector 0x12e010 len 4096 err no 10
BTRFS: error (device dm-0) in write_all_supers:4110: errno=-5 IO failure (1 errors while writing supers)
BTRFS: error (device dm-0) in btrfs_sync_log:3308: errno=-5 IO failure

The steps that lead to this crash are the following:
1) We are at transaction N;
2) We have two tasks with a transaction handle attached to transaction N.
Task A and Task B. Task B is doing an fsync;
3) Task B is at btrfs_sync_log(), and has saved fs_info->log_root_tree
into a local variable named 'log_root_tree' at the top of
btrfs_sync_log(). Task B is about to call write_all_supers(), but
before that...
4) Task A calls btrfs_commit_transaction(), and after it sets the
transaction state to TRANS_STATE_COMMIT_START, an error happens before
it w

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix hashtab overflow check on 32-bit arches
The hashtab code relies on roundup_pow_of_two() to compute the number of
hash buckets, and contains an overflow check by checking if the
resulting value is 0. However, on 32-bit arches, the roundup code itself
can overflow by doing a 32-bit left-shift of an unsigned long value,
which is undefined behaviour, so it is not guaranteed to truncate
neatly. This was triggered by syzbot on the DEVMAP_HASH type, which
contains the same check, copied from the hashtab code. So apply the same
fix to hashtab, by moving the overflow check to before the roundup.

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: rp2: use 'request_firmware' instead of 'request_firmware_nowait'
In 'rp2_probe', the driver registers 'rp2_uart_interrupt' then calls
'rp2_fw_cb' through 'request_firmware_nowait'. In 'rp2_fw_cb', if the
firmware don't exists, function just return without initializing ports
of 'rp2_card'. But now the interrupt handler function has been
registered, and when an interrupt comes, 'rp2_uart_interrupt' may access
those ports then causing NULL pointer dereference or other bugs.
Because the driver does some initialization work in 'rp2_fw_cb', in
order to make the driver ready to handle interrupts, 'request_firmware'
should be used instead of asynchronous 'request_firmware_nowait'.
This report reveals it:
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Fix RX consumer index logic in the error path.
In bnxt_rx_pkt(), the RX buffers are expected to complete in order.
If the RX consumer index indicates an out of order buffer completion,
it means we are hitting a hardware bug and the driver will abort all
remaining RX packets and reset the RX ring. The RX consumer index
that we pass to bnxt_discard_rx() is not correct. We should be
passing the current index (tmp_raw_cons) instead of the old index
(raw_cons). This bug can cause us to be at the wrong index when
trying to abort the next RX packet. It can crash like this:
#0 [ffff9bbcdf5c39a8] machine_kexec at ffffffff9b05e007
#1 [ffff9bbcdf5c3a00] __crash_kexec at ffffffff9b111232

Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/hfi1: Fix a memleak in init_credit_return
When dma_alloc_coherent fails to allocate dd->cr_base[i].va,
init_credit_return should deallocate dd->cr_base and
dd->cr_base[i] that allocated before. Or those resources
would be never freed and a memleak is triggered.

Summary
In the Linux kernel, the following vulnerability has been resolved:
smb3: fix temporary data corruption in collapse range
collapse range doesn't discard the affected cached region
so can risk temporarily corrupting the file data. This
fixes xfstest generic/031
I also decided to merge a minor cleanup to this into the same patch
(avoiding rereading inode size repeatedly unnecessarily) to make it
clearer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix memory ordering between normal and ordered work functions
Ordered work functions aren't guaranteed to be handled by the same thread
which executed the normal work functions. The only way execution between
normal/ordered functions is synchronized is via the WORK_DONE_BIT,
unfortunately the used bitops don't guarantee any ordering whatsoever.
This manifested as seemingly inexplicable crashes on ARM64, where
async_chunk::inode is seen as non-null in async_cow_submit which causes
submit_compressed_extents to be called and crash occurs because
async_chunk::inode suddenly became NULL. The call trace was similar to:
pc : submit_compressed_extents+0x38/0x3d0
lr : async_cow_submit+0x50/0xd0
sp : ffff800015d4bc20
<registers omitted for brevity>
Call trace:
submit_compressed_extents+0x38/0x3d0
async_cow_submit+0x50/0xd0
run_ordered_work+0xc8/0x280
btrfs_work_helper+0x98/0x250
process_one_work+0x1f0/0x4ac
worker_thread+0x188/0x504
kthread+0x110/0x114
ret_from_fork+0x10/0x18
Fix this by adding respective barrier calls which ensure that all
accesses preceding setting of WORK_DONE_BIT are strictly ordered before
setting the flag. At the same time add a read barrier after reading of
WORK_DONE_BIT in run_ordered_work which ensures all subsequent loads
would be strictly ordered after reading the bit. This in turn ensures
are all accesses before WORK_DONE_BIT are going to be strictly ordered
before any access that can occur in ordered_func.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rt2x00: restart beacon queue when hardware reset
When a hardware reset is triggered, all registers are reset, so all
queues are forced to stop in hardware interface. However, mac80211
will not automatically stop the queue. If we don't manually stop the
beacon queue, the queue will be deadlocked and unable to start again.
This patch fixes the issue where Apple devices cannot connect to the
AP after calling ieee80211_restart_hw().

Summary
In the Linux kernel, the following vulnerability has been resolved:
tun: limit printing rate when illegal packet received by tun dev
vhost_worker will call tun call backs to receive packets. If too many
illegal packets arrives, tun_do_read will keep dumping packet contents.
When console is enabled, it will costs much more cpu time to dump
packet and soft lockup will be detected.
net_ratelimit mechanism can be used to limit the dumping rate.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs: sysfs: Fix reference leak in sysfs_break_active_protection()
The sysfs_break_active_protection() routine has an obvious reference
leak in its error path. If the call to kernfs_find_and_get() fails then
kn will be NULL, so the companion sysfs_unbreak_active_protection()
routine won't get called (and would only cause an access violation by
trying to dereference kn->parent if it was called). As a result, the
reference to kobj acquired at the start of the function will never be
released.
Fix the leak by adding an explicit kobject_put() call when kn is NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/ipoib: Fix mcast list locking
Releasing the `priv->lock` while iterating the `priv->multicast_list` in
`ipoib_mcast_join_task()` opens a window for `ipoib_mcast_dev_flush()` to
remove the items while in the middle of iteration. If the mcast is removed
while the lock was dropped, the for loop spins forever resulting in a hard
lockup (as was reported on RHEL 4.18.0-372.75.1.el8_6 kernel):
Task A (kworker/u72:2 below) | Task B (kworker/u72:0 below)
-----------------------------------+-----------------------------------
ipoib_mcast_join_task(work) | ipoib_ib_dev_flush_light(work)
spin_lock_irq(&priv->lock) | __ipoib_ib_dev_flush(priv, ...)
list_for_each_entry(mcast, | ipoib_mcast_dev_flush(dev = priv->dev)
&priv->multicast_list, list) |
ipoib_mcast_join(dev, mcast) |
spin_unlock_irq(&priv->lock) |
| spin_lock_irqsave(&priv->lock, flags)
| list_for_each_entry_safe(mcast, tmcast,
| &priv->multicast_list, list)
| list_del(&mcast->list);
| list_add_tail(&mcast->list, &remove_list)
| spin_unlock_irqrestore(&priv->lock, flags)
spin_lock_irq(&priv->lock) |
| ipoib_mcast_remove_list(&remove_list)
(Here, `mcast` is no longer on the | list_for_each_entry_safe(mcast, tmcast,
`priv->multicast_list` and we keep | remove_list, list)
spinning on the `remove_list` of | >>> wait_for_completion(&mcast->done)
the other thread which is blocked |
and the list is still valid on |
it's stack.)
Fix this by keeping the lock held and changing to GFP_ATOMIC to prevent
eventual sleeps.
Unfortunately we could not reproduce the lockup and confirm this fix but
based on the code review I think this fix should address such lockups.

Summary
In the Linux kernel, the following vulnerability has been resolved:
md/raid1: properly indicate failure when ending a failed write request
This patch addresses a data corruption bug in raid1 arrays using bitmaps.
Without this fix, the bitmap bits for the failed I/O end up being cleared.
Since we are in the failure leg of raid1_end_write_request, the request
either needs to be retried (R1BIO_WriteError) or failed (R1BIO_Degraded).

Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: Fix kernel crash during module removal
The driver incorrectly frees client instance and subsequent
i40e module removal leads to kernel crash.
Reproducer:
1. Do ethtool offline test followed immediately by another one
host# ethtool -t eth0 offline; ethtool -t eth0 offline
2. Remove recursively irdma module that also removes i40e module
host# modprobe -r irdma

Two offline tests cause IRDMA driver failure (ETIMEDOUT) and this
failure is indicated back to i40e_client_subtask() that calls
i40e_client_del_instance() to free client instance referenced
by pf->cinst and sets this pointer to NULL. During the module
removal i40e_remove() calls i40e_lan_del_device() that dereferences
pf->cinst that is NULL -> crash.
Do not remove client instance when client open callbacks fails and
just clear __I40E_CLIENT_INSTANCE_OPENED bit. The driver also needs
to take care about this situation (when netdev is up and client
is NOT opened) in i40e_notify_client_of_netdev_close() and
calls client close callback only when __I40E_CLIENT_INSTANCE_OPENED
is set.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ceph: fix deadlock or deadcode of misusing dget()
The lock order is incorrect between denty and its parent, we should
always make sure that the parent get the lock first.
But since this deadcode is never used and the parent dir will always
be set from the callers, let's just remove it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
do_sys_name_to_handle(): use kzalloc() to fix kernel-infoleak
syzbot identified a kernel information leak vulnerability in
do_sys_name_to_handle() and issued the following report [1].

Per Chuck Lever's suggestion, use kzalloc() instead of kmalloc() to
solve the problem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/dasd: fix double module refcount decrement
Once the discipline is associated with the device, deleting the device
takes care of decrementing the module's refcount. Doing it manually on
this error path causes refcount to artificially decrease on each error
while it should just stay the same.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/srp: Do not call scsi_done() from srp_abort()
After scmd_eh_abort_handler() has called the SCSI LLD eh_abort_handler
callback, it performs one of the following actions:
* Call scsi_queue_insert().
* Call scsi_finish_command().
* Call scsi_eh_scmd_add().
Hence, SCSI abort handlers must not call scsi_done(). Otherwise all
the above actions would trigger a use-after-free. Hence remove the
scsi_done() call from srp_abort(). Keep the srp_free_req() call
before returning SUCCESS because we may not see the command again if
SUCCESS is returned.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/64s: Fix crashes when toggling entry flush barrier
The entry flush mitigation can be enabled/disabled at runtime via a
debugfs file (entry_flush), which causes the kernel to patch itself to
enable/disable the relevant mitigations.
However depending on which mitigation we're using, it may not be safe to
do that patching while other CPUs are active. For example the following
crash:
sleeper[15639]: segfault (11) at c000000000004c20 nip c000000000004c20 lr c000000000004c20
Shows that we returned to userspace with a corrupted LR that points into
the kernel, due to executing the partially patched call to the fallback
entry flush (ie. we missed the LR restore).
Fix it by doing the patching under stop machine. The CPUs that aren't
doing the patching will be spinning in the core of the stop machine
logic. That is currently sufficient for our purposes, because none of
the patching we do is to that code or anywhere in the vicinity.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ARM: 9064/1: hw_breakpoint: Do not directly check the event's overflow_handler hook
The commit 1879445dfa7b ("perf/core: Set event's default
::overflow_handler()") set a default event->overflow_handler in
perf_event_alloc(), and replace the check event->overflow_handler with
is_default_overflow_handler(), but one is missing.
Currently, the bp->overflow_handler can not be NULL. As a result,
enable_single_step() is always not invoked.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PM / devfreq: Fix buffer overflow in trans_stat_show
Fix buffer overflow in trans_stat_show().
Convert simple snprintf to the more secure scnprintf with size of
PAGE_SIZE.
Add condition checking if we are exceeding PAGE_SIZE and exit early from
loop. Also add at the end a warning that we exceeded PAGE_SIZE and that
stats is disabled.
Return -EFBIG in the case where we don't have enough space to write the
full transition table.
Also document in the ABI that this function can return -EFBIG error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: core: Do core softreset when switch mode
According to the programming guide, to switch mode for DRD controller,
the driver needs to do the following.
To switch from device to host:
1. Reset controller with GCTL.CoreSoftReset
2. Set GCTL.PrtCapDir(host mode)
3. Reset the host with USBCMD.HCRESET
4. Then follow up with the initializing host registers sequence
To switch from host to device:
1. Reset controller with GCTL.CoreSoftReset
2. Set GCTL.PrtCapDir(device mode)
3. Reset the device with DCTL.CSftRst
4. Then follow up with the initializing registers sequence
Currently we're missing step 1) to do GCTL.CoreSoftReset and step 3) of
switching from host to device. John Stult reported a lockup issue seen
with HiKey960 platform without these steps[1]. Similar issue is observed
with Ferry's testing platform[2].
So, apply the required steps along with some fixes to Yu Chen's and John
Stultz's version. The main fixes to their versions are the missing wait
for clocks synchronization before clearing GCTL.CoreSoftReset and only
apply DCTL.CSftRst when switching from host to device.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: core: Fix scsi_mode_sense() buffer length handling
Several problems exist with scsi_mode_sense() buffer length handling:
1) The allocation length field of the MODE SENSE(10) command is 16-bits,
occupying bytes 7 and 8 of the CDB. With this command, access to mode
pages larger than 255 bytes is thus possible. However, the CDB
allocation length field is set by assigning len to byte 8 only, thus
truncating buffer length larger than 255.
2) If scsi_mode_sense() is called with len smaller than 8 with
sdev->use_10_for_ms set, or smaller than 4 otherwise, the buffer length
is increased to 8 and 4 respectively, and the buffer is zero filled
with these increased values, thus corrupting the memory following the
buffer.
Fix these 2 problems by using put_unaligned_be16() to set the allocation
length field of MODE SENSE(10) CDB and by returning an error when len is
too small.
Furthermore, if len is larger than 255B, always try MODE SENSE(10) first,
even if the device driver did not set sdev->use_10_for_ms. In case of
invalid opcode error for MODE SENSE(10), access to mode pages larger than
255 bytes are not retried using MODE SENSE(6). To avoid buffer length
overflows for the MODE_SENSE(10) case, check that len is smaller than 65535
bytes.
While at it, also fix the folowing:
* Use get_unaligned_be16() to retrieve the mode data length and block
descriptor length fields of the mode sense reply header instead of using
an open coded calculation.
* Fix the kdoc dbd argument explanation: the DBD bit stands for Disable
Block Descriptor, which is the opposite of what the dbd argument
description was.

With this command, access to mode\n pages larger than 255 bytes is thus possible. However, the CDB\n allocation length field is set by assigning len to byte 8 only, thus\n truncating buffer length larger than 255.\n\n 2) If scsi_mode_sense() is called with len smaller than 8 with\n sdev-\u003euse_10_for_ms set, or smaller than 4 otherwise, the buffer length\n is increased to 8 and 4 respectively, and the buffer is zero filled\n with these increased values, thus corrupting the memory following the\n buffer.\n\nFix these 2 problems by using put_unaligned_be16() to set the allocation\nlength field of MODE SENSE(10) CDB and by returning an error when len is\ntoo small.\n\nFurthermore, if len is larger than 255B, always try MODE SENSE(10) first,\neven if the device driver did not set sdev-\u003euse_10_for_ms. In case of\ninvalid opcode error for MODE SENSE(10), access to mode pages larger than\n255 bytes are not retried using MODE SENSE(6). To avoid buffer length\noverflows for the MODE_SENSE(10) case, check that len is smaller than 65535\nbytes.\n\nWhile at it, also fix the folowing:\n\n * Use get_unaligned_be16() to retrieve the mode data length and block\n descriptor length fields of the mode sense reply header instead of using\n an open coded calculation.\n\n * Fix the kdoc dbd argument explanation: the DBD bit stands for Disable\n Block Descriptor, which is the opposite of what the dbd argument\n description was."

CWE
- CWE-416 - Use After Free
Summary
A flaw was found in the ATA over Ethernet (AoE) driver in the Linux kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on `struct net_device`, and a use-after-free can be triggered by racing between the free on the struct and the access through the `skbtxq` global queue. This could lead to a denial of service condition or potential code execution.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/bnx2x: Prevent access to a freed page in page_pool
Fix race condition leading to system crash during EEH error handling
During EEH error recovery, the bnx2x driver's transmit timeout logic
could cause a race condition when handling reset tasks. The
bnx2x_tx_timeout() schedules reset tasks via bnx2x_sp_rtnl_task(),
which ultimately leads to bnx2x_nic_unload(). In bnx2x_nic_unload()
SGEs are freed using bnx2x_free_rx_sge_range(). However, this could
overlap with the EEH driver's attempt to reset the device using
bnx2x_io_slot_reset(), which also tries to free SGEs. This race
condition can result in system crashes due to accessing freed memory
locations in bnx2x_free_rx_sge()
799 static inline void bnx2x_free_rx_sge(struct bnx2x *bp,
800 struct bnx2x_fastpath *fp, u16 index)
801 {
802 struct sw_rx_page *sw_buf = &fp->rx_page_ring[index];
803 struct page *page = sw_buf->page;
....
where sw_buf was set to NULL after the call to dma_unmap_page()
by the preceding thread.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: fix a crash if ->get_sset_count() fails
If ds->ops->get_sset_count() fails then it "count" is a negative error
code such as -EOPNOTSUPP. Because "i" is an unsigned int, the negative
error code is type promoted to a very high value and the loop will
corrupt memory until the system crashes.
Fix this by checking for error codes and changing the type of "i" to
just int.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: fix null pointer dereference on pointer cs_desc
The pointer cs_desc return from snd_usb_find_clock_source could
be null, so there is a potential null pointer dereference issue.
Fix this by adding a null check before dereference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: sis: Error out if pixclock equals zero
The userspace program could pass any values to the driver through
ioctl() interface. If the driver doesn't check the value of pixclock,
it may cause divide-by-zero error.
In sisfb_check_var(), var->pixclock is used as a divisor to caculate
drate before it is checked against zero. Fix this by checking it
at the beginning.
This is similar to CVE-2022-3061 in i740fb which was fixed by
commit 15cf0b8.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: hub: Guard against accesses to uninitialized BOS descriptors
Many functions in drivers/usb/core/hub.c and drivers/usb/core/hub.h
access fields inside udev->bos without checking if it was allocated and
initialized. If usb_get_bos_descriptor() fails for whatever
reason, udev->bos will be NULL and those accesses will result in a
crash:

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: hso: fix null-ptr-deref during tty device unregistration
Multiple ttys try to claim the same the minor number causing a double
unregistration of the same device. The first unregistration succeeds
but the next one results in a null-ptr-deref.
The get_free_serial_index() function returns an available minor number
but doesn't assign it immediately. The assignment is done by the caller
later. But before this assignment, calls to get_free_serial_index()
would return the same minor number.
Fix this by modifying get_free_serial_index to assign the minor number
immediately after one is found to be and rename it to obtain_minor()
to better reflect what it does. Similary, rename set_serial_by_index()
to release_minor() and modify it to free up the minor number of the
given hso_serial. Every obtain_minor() should have corresponding
release_minor() call.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: remove device from smcd_dev_list after failed device_add()
If the device_add() for a smcd_dev fails, there's no cleanup step that
rolls back the earlier list_add(). The device subsequently gets freed,
and we end up with a corrupted list.
Add some error handling that removes the device from the list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Drivers: hv: vmbus: Use after free in __vmbus_open()
The "open_info" variable is added to the &vmbus_connection.chn_msg_list,
but the error handling frees "open_info" without removing it from the
list. This will result in a use after free. First remove it from the
list, and then free it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mtd: require write permissions for locking and badblock ioctls
MEMLOCK, MEMUNLOCK and OTPLOCK modify protection bits. Thus require
write permission. Depending on the hardware MEMLOCK might even be
write-once, e.g. for SPI-NOR flashes with their WP# tied to GND. OTPLOCK
is always write-once.
MEMSETBADBLOCK modifies the bad block table.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Prevent deadlock while disabling aRFS
When disabling aRFS under the `priv->state_lock`, any scheduled
aRFS works are canceled using the `cancel_work_sync` function,
which waits for the work to end if it has already started.
However, while waiting for the work handler, the handler will
try to acquire the `state_lock` which is already acquired.
The worker acquires the lock to delete the rules if the state
is down, which is not the worker's responsibility since
disabling aRFS deletes the rules.
Add an aRFS state variable, which indicates whether the aRFS is
enabled and prevent adding rules when the aRFS is disabled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nbd: Fix NULL pointer in flush_workqueue
Open /dev/nbdX first, the config_refs will be 1 and
the pointers in nbd_device are still null. Disconnect
/dev/nbdX, then reference a null recv_workq. The
protection by config_refs in nbd_genl_disconnect is useless.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm-crypt: don't modify the data when using authenticated encryption
It was said that authenticated encryption could produce invalid tag when
the data that is being encrypted is modified [1]. So, fix this problem by
copying the data into the clone bio first and then encrypt them inside the
clone bio.
This may reduce performance, but it is needed to prevent the user from
corrupting the device by writing data with O_DIRECT and modifying them at
the same time.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix memory leak in ext4_fill_super
Buffer head references must be released before calling kill_bdev();
otherwise the buffer head (and its page referenced by b_data) will not
be freed by kill_bdev, and subsequently that bh will be leaked.
If blocksizes differ, sb_set_blocksize() will kill current buffers and
page cache by using kill_bdev(). And then super block will be reread
again but using correct blocksize this time. sb_set_blocksize() didn't
fully free superblock page and buffer head, and being busy, they were
not freed and instead leaked.
This can easily be reproduced by calling an infinite loop of:
systemctl start <ext4_on_lvm>.mount, and
systemctl stop <ext4_on_lvm>.mount
... since systemd creates a cgroup for each slice which it mounts, and
the bh leak get amplified by a dying memory cgroup that also never
gets freed, and memory consumption is much more easily noticed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFS: fix an incorrect limit in filelayout_decode_layout()
The "sizeof(struct nfs_fh)" is two bytes too large and could lead to
memory corruption. It should be NFS_MAXFHSIZE because that's the size
of the ->data[] buffer.
I reversed the size of the arguments to put the variable on the left.

Summary
In the Linux kernel, the following vulnerability has been resolved:
thermal: Fix NULL pointer dereferences in of_thermal_ functions
of_parse_thermal_zones() parses the thermal-zones node and registers a
thermal_zone device for each subnode. However, if a thermal zone is
consuming a thermal sensor and that thermal sensor device hasn't probed
yet, an attempt to set trip_point_*_temp for that thermal zone device
can cause a NULL pointer dereference. Fix it.
console:/sys/class/thermal/thermal_zone87 # echo 120000 > trip_point_0_temp
...
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000020

While at it, fix the possible NULL pointer dereference in other
functions as well: of_thermal_get_temp(), of_thermal_set_emul_temp(),
of_thermal_get_trend().

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm rq: fix double free of blk_mq_tag_set in dev remove after table load fails
When loading a device-mapper table for a request-based mapped device,
and the allocation/initialization of the blk_mq_tag_set for the device
fails, a following device remove will cause a double free.
E.g. (dmesg):
device-mapper: core: Cannot initialize queue for request-based dm-mq mapped device
device-mapper: ioctl: unable to set up device queue for new table.
Unable to handle kernel pointer dereference in virtual kernel address space
Failing address: 0305e098835de000 TEID: 0305e098835de803
Fault in home space mode while using kernel ASCE.

Kernel panic - not syncing: Fatal exception: panic_on_oops
When allocation/initialization of the blk_mq_tag_set fails in
dm_mq_init_request_queue(), it is uninitialized/freed, but the pointer
is not reset to NULL; so when dev_remove() later gets into
dm_mq_cleanup_mapped_device() it sees the pointer and tries to
uninitialize and free it again.
Fix this by setting the pointer to NULL in dm_mq_init_request_queue()
error-handling. Also set it to NULL in dm_mq_cleanup_mapped_device().

Summary
In the Linux kernel, the following vulnerability has been resolved:
aoe: fix the potential use-after-free problem in aoecmd_cfg_pkts
This patch is against CVE-2023-6270. The description of cve is:
A flaw was found in the ATA over Ethernet (AoE) driver in the Linux
kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on
`struct net_device`, and a use-after-free can be triggered by racing
between the free on the struct and the access through the `skbtxq`
global queue. This could lead to a denial of service condition or
potential code execution.
In aoecmd_cfg_pkts(), it always calls dev_put(ifp) when skb initial
code is finished. But the net_device ifp will still be used in
later tx()->dev_queue_xmit() in kthread. Which means that the
dev_put(ifp) should NOT be called in the success path of skb
initial code in aoecmd_cfg_pkts(). Otherwise tx() may run into
use-after-free because the net_device is freed.
This patch removed the dev_put(ifp) in the success path in
aoecmd_cfg_pkts(), and added dev_put() after skb xmit in tx().

Summary
In the Linux kernel, the following vulnerability has been resolved:
tipc: skb_linearize the head skb when reassembling msgs
It's not a good idea to append the frag skb to a skb's frag_list if
the frag_list already has skbs from elsewhere, such as this skb was
created by pskb_copy() where the frag_list was cloned (all the skbs
in it were skb_get'ed) and shared by multiple skbs.
However, the new appended frag skb should have been only seen by the
current skb. Otherwise, it will cause use after free crashes as this
appended frag skb are seen by multiple skbs but it only got skb_get
called once.
The same thing happens with a skb updated by pskb_may_pull() with a
skb_cloned skb. Li Shuang has reported quite a few crashes caused
by this when doing testing over macvlan devices:

...
This patch is to fix it by linearizing the head skb if it has frag_list
set in tipc_buf_append(). Note that we choose to do this before calling
skb_unshare(), as __skb_linearize() will avoid skb_copy(). Also, we can
not just drop the frag_list either as the early time.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix link down processing to address NULL pointer dereference
If an FC link down transition while PLOGIs are outstanding to fabric well
known addresses, outstanding ABTS requests may result in a NULL pointer
dereference. Driver unload requests may hang with repeated "2878" log
messages.
The Link down processing results in ABTS requests for outstanding ELS
requests. The Abort WQEs are sent for the ELSs before the driver had set
the link state to down. Thus the driver is sending the Abort with the
expectation that an ABTS will be sent on the wire. The Abort request is
stalled waiting for the link to come up. In some conditions the driver may
auto-complete the ELSs thus if the link does come up, the Abort completions
may reference an invalid structure.
Fix by ensuring that Abort set the flag to avoid link traffic if issued due
to conditions where the link failed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: s390: vsie: fix race during shadow creation
Right now it is possible to see gmap->private being zero in
kvm_s390_vsie_gmap_notifier resulting in a crash. This is due to the
fact that we add gmap->private == kvm after creation:
static int acquire_gmap_shadow(struct kvm_vcpu *vcpu,
struct vsie_page *vsie_page)
{
[...]
gmap = gmap_shadow(vcpu->arch.gmap, asce, edat);
if (IS_ERR(gmap))
return PTR_ERR(gmap);
gmap->private = vcpu->kvm;
Let children inherit the private field of the parent.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix double-free of blocks due to wrong extents moved_len
In ext4_move_extents(), moved_len is only updated when all moves are
successfully executed, and only discards orig_inode and donor_inode
preallocations when moved_len is not zero. When the loop fails to exit
after successfully moving some extents, moved_len is not updated and
remains at 0, so it does not discard the preallocations.
If the moved extents overlap with the preallocated extents, the
overlapped extents are freed twice in ext4_mb_release_inode_pa() and
ext4_process_freed_data() (as described in commit 94d7c16cbbbd ("ext4:
Fix double-free of blocks with EXT4_IOC_MOVE_EXT")), and bb_free is
incremented twice. Hence when trim is executed, a zero-division bug is
triggered in mb_update_avg_fragment_size() because bb_free is not zero
and bb_fragments is zero.
Therefore, update move_len after each extent move to avoid the issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
userfaultfd: release page in error path to avoid BUG_ON
Consider the following sequence of events:
1. Userspace issues a UFFD ioctl, which ends up calling into
shmem_mfill_atomic_pte(). We successfully account the blocks, we
shmem_alloc_page(), but then the copy_from_user() fails. We return
-ENOENT. We don't release the page we allocated.
2. Our caller detects this error code, tries the copy_from_user() after
dropping the mmap_lock, and retries, calling back into
shmem_mfill_atomic_pte().
3. Meanwhile, let's say another process filled up the tmpfs being used.
4. So shmem_mfill_atomic_pte() fails to account blocks this time, and
immediately returns - without releasing the page.
This triggers a BUG_ON in our caller, which asserts that the page
should always be consumed, unless -ENOENT is returned.
To fix this, detect if we have such a "dangling" page when accounting
fails, and if so, release it before returning.

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/dasd: fix Oops in dasd_alias_get_start_dev due to missing pavgroup
Fix Oops in dasd_alias_get_start_dev() function caused by the pavgroup
pointer being NULL.
The pavgroup pointer is checked on the entrance of the function but
without the lcu->lock being held. Therefore there is a race window
between dasd_alias_get_start_dev() and _lcu_update() which sets
pavgroup to NULL with the lcu->lock held.
Fix by checking the pavgroup pointer with lcu->lock held.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: go7007: fix a memleak in go7007_load_encoder
In go7007_load_encoder, bounce(i.e. go->boot_fw), is allocated without
a deallocation thereafter. After the following call chain:
saa7134_go7007_init
|-> go7007_boot_encoder
|-> go7007_load_encoder
|-> kfree(go)
go is freed and thus bounce is leaked.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NTB: fix possible name leak in ntb_register_device()
If device_register() fails in ntb_register_device(), the device name
allocated by dev_set_name() should be freed. As per the comment in
device_register(), callers should use put_device() to give up the
reference in the error path. So fix this by calling put_device() in the
error path so that the name can be freed in kobject_cleanup().
As a result of this, put_device() in the error path of
ntb_register_device() is removed and the actual error is returned.

Summary
In the Linux kernel, the following vulnerability has been resolved:
platform/x86: dell-smbios-wmi: Fix oops on rmmod dell_smbios
init_dell_smbios_wmi() only registers the dell_smbios_wmi_driver on systems
where the Dell WMI interface is supported. While exit_dell_smbios_wmi()
unregisters it unconditionally, this leads to the following oops:
[ 175.722921] ------------[ cut here ]------------
[ 175.722925] Unexpected driver unregister!
[ 175.722939] WARNING: CPU: 1 PID: 3630 at drivers/base/driver.c:194 driver_unregister+0x38/0x40
...
[ 175.723089] Call Trace:
[ 175.723094] cleanup_module+0x5/0xedd [dell_smbios]
...
[ 175.723148] ---[ end trace 064c34e1ad49509d ]---
Make the unregister happen on the same condition the register happens
to fix this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-tpg: fix some memleaks in tpg_alloc
In tpg_alloc, resources should be deallocated in each and every
error-handling paths, since they are allocated in for statements.
Otherwise there would be memleaks because tpg_free is called only when
tpg_alloc return 0.

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:

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:
netlabel: fix out-of-bounds memory accesses
There are two array out-of-bounds memory accesses, one in
cipso_v4_map_lvl_valid(), the other in netlbl_bitmap_walk(). Both
errors are embarassingly simple, and the fixes are straightforward.
As a FYI for anyone backporting this patch to kernels prior to v4.8,
you'll want to apply the netlbl_bitmap_walk() patch to
cipso_v4_bitmap_walk() as netlbl_bitmap_walk() doesn't exist before
Linux v4.8.

The system was under memory stress where driver was not able to allocate an
SRB to carry out error recovery of cable pull. The failure to flush causes
upper layer to start modifying scsi_cmnd. When the system frees up some
memory, the subsequent cable pull trigger another command flush. At this
point the driver access a null pointer when attempting to DMA unmap the
SGL.
Add a check to make sure commands are flush back on session tear down to
prevent the null pointer access.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Reserve extra IRQ vectors
Commit a6dcfe08487e ("scsi: qla2xxx: Limit interrupt vectors to number of
CPUs") lowers the number of allocated MSI-X vectors to the number of CPUs.
That breaks vector allocation assumptions in qla83xx_iospace_config(),
qla24xx_enable_msix() and qla2x00_iospace_config(). Either of the functions
computes maximum number of qpairs as:
ha->max_qpairs = ha->msix_count - 1 (MB interrupt) - 1 (default
response queue) - 1 (ATIO, in dual or pure target mode)
max_qpairs is set to zero in case of two CPUs and initiator mode. The
number is then used to allocate ha->queue_pair_map inside
qla2x00_alloc_queues(). No allocation happens and ha->queue_pair_map is
left NULL but the driver thinks there are queue pairs available.
qla2xxx_queuecommand() tries to find a qpair in the map and crashes:
if (ha->mqenable) {
uint32_t tag;
uint16_t hwq;
struct qla_qpair *qpair = NULL;
tag = blk_mq_unique_tag(cmd->request);
hwq = blk_mq_unique_tag_to_hwq(tag);
qpair = ha->queue_pair_map[hwq]; # <- HERE
if (qpair)
return qla2xxx_mqueuecommand(host, cmd, qpair);
}

The driver should allocate enough vectors to provide every CPU it's own HW
queue and still handle reserved (MB, RSP, ATIO) interrupts.
The change fixes the crash on dual core VM and prevents unbalanced QP
allocation where nr_hw_queues is two less than the number of CPUs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ceph: prevent use-after-free in encode_cap_msg()
In fs/ceph/caps.c, in encode_cap_msg(), "use after free" error was
caught by KASAN at this line - 'ceph_buffer_get(arg->xattr_buf);'. This
implies before the refcount could be increment here, it was freed.
In same file, in "handle_cap_grant()" refcount is decremented by this
line - 'ceph_buffer_put(ci->i_xattrs.blob);'. It appears that a race
occurred and resource was freed by the latter line before the former
line could increment it.
encode_cap_msg() is called by __send_cap() and __send_cap() is called by
ceph_check_caps() after calling __prep_cap(). __prep_cap() is where
arg->xattr_buf is assigned to ci->i_xattrs.blob. This is the spot where
the refcount must be increased to prevent "use after free" error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-mq: fix IO hang from sbitmap wakeup race
In blk_mq_mark_tag_wait(), __add_wait_queue() may be re-ordered
with the following blk_mq_get_driver_tag() in case of getting driver
tag failure.
Then in __sbitmap_queue_wake_up(), waitqueue_active() may not observe
the added waiter in blk_mq_mark_tag_wait() and wake up nothing, meantime
blk_mq_mark_tag_wait() can't get driver tag successfully.
This issue can be reproduced by running the following test in loop, and
fio hang can be observed in < 30min when running it on my test VM
in laptop.
modprobe -r scsi_debug
modprobe scsi_debug delay=0 dev_size_mb=4096 max_queue=1 host_max_queue=1 submit_queues=4
dev=`ls -d /sys/bus/pseudo/drivers/scsi_debug/adapter*/host*/target*/*/block/* | head -1 | xargs basename`
fio --filename=/dev/"$dev" --direct=1 --rw=randrw --bs=4k --iodepth=1 \
--runtime=100 --numjobs=40 --time_based --name=test \
--ioengine=libaio
Fix the issue by adding one explicit barrier in blk_mq_mark_tag_wait(), which
is just fine in case of running out of tag.

Summary
In the Linux kernel, the following vulnerability has been resolved:
pid: take a reference when initializing `cad_pid`
During boot, kernel_init_freeable() initializes `cad_pid` to the init
task's struct pid. Later on, we may change `cad_pid` via a sysctl, and
when this happens proc_do_cad_pid() will increment the refcount on the
new pid via get_pid(), and will decrement the refcount on the old pid
via put_pid(). As we never called get_pid() when we initialized
`cad_pid`, we decrement a reference we never incremented, can therefore
free the init task's struct pid early. As there can be dangling
references to the struct pid, we can later encounter a use-after-free
(e.g. when delivering signals).
This was spotted when fuzzing v5.13-rc3 with Syzkaller, but seems to
have been around since the conversion of `cad_pid` to struct pid in
commit 9ec52099e4b8 ("[PATCH] replace cad_pid by a struct pid") from the
pre-KASAN stone age of v2.6.19.
Fix this by getting a reference to the init task's struct pid when we
assign it to `cad_pid`.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\npid: take a reference when initializing `cad_pid`\n\nDuring boot, kernel_init_freeable() initializes `cad_pid` to the init\ntask\u0027s struct pid. Later on, we may change `cad_pid` via a sysctl, and\nwhen this happens proc_do_cad_pid() will increment the refcount on the\nnew pid via get_pid(), and will decrement the refcount on the old pid\nvia put_pid(). As we never called get_pid() when we initialized\n`cad_pid`, we decrement a reference we never incremented, can therefore\nfree the init task\u0027s struct pid early. As there can be dangling\nreferences to the struct pid, we can later encounter a use-after-free\n(e.g. when delivering signals).\n\nThis was spotted when fuzzing v5.13-rc3 with Syzkaller, but seems to\nhave been around since the conversion of `cad_pid` to struct pid in\ncommit 9ec52099e4b8 (\"[PATCH] replace cad_pid by a struct pid\") from the\npre-KASAN stone age of v2.6.19.\n\nFix this by getting a reference to the init task\u0027s struct pid when we\nassign it to `cad_pid`.\n\nFull KASAN splat below.\n\n ==================================================================\n BUG: KASAN: use-after-free in ns_of_pid include/linux/pid.h:153 [inline]\n BUG: KASAN: use-after-free in task_active_pid_ns+0xc0/0xc8 kernel/pid.c:509\n Read of size 4 at addr ffff23794dda0004 by task syz-executor.0/273\n\n CPU: 1 PID: 273 Comm: syz-executor.0 Not tainted 5.12.0-00001-g9aef892b2d15 #1\n Hardware name: linux,dummy-virt (DT)\n Call trace:\n ns_of_pid include/linux/pid.h:153 [inline]\n task_active_pid_ns+0xc0/0xc8 kernel/pid.c:509\n do_notify_parent+0x308/0xe60 kernel/signal.c:1950\n exit_notify kernel/exit.c:682 [inline]\n do_exit+0x2334/0x2bd0 kernel/exit.c:845\n do_group_exit+0x108/0x2c8 kernel/exit.c:922\n get_signal+0x4e4/0x2a88 kernel/signal.c:2781\n do_signal arch/arm64/kernel/signal.c:882 [inline]\n do_notify_resume+0x300/0x970 arch/arm64/kernel/signal.c:936\n work_pending+0xc/0x2dc\n\n Allocated by task 0:\n slab_post_alloc_hook+0x50/0x5c0 mm/slab.h:516\n slab_alloc_node mm/slub.c:2907 [inline]\n slab_alloc mm/slub.c:2915 [inline]\n kmem_cache_alloc+0x1f4/0x4c0 mm/slub.c:2920\n alloc_pid+0xdc/0xc00 kernel/pid.c:180\n copy_process+0x2794/0x5e18 kernel/fork.c:2129\n kernel_clone+0x194/0x13c8 kernel/fork.c:2500\n kernel_thread+0xd4/0x110 kernel/fork.c:2552\n rest_init+0x44/0x4a0 init/main.c:687\n arch_call_rest_init+0x1c/0x28\n start_kernel+0x520/0x554 init/main.c:1064\n 0x0\n\n Freed by task 270:\n slab_free_hook mm/slub.c:1562 [inline]\n slab_free_freelist_hook+0x98/0x260 mm/slub.c:1600\n slab_free mm/slub.c:3161 [inline]\n kmem_cache_free+0x224/0x8e0 mm/slub.c:3177\n put_pid.part.4+0xe0/0x1a8 kernel/pid.c:114\n put_pid+0x30/0x48 kernel/pid.c:109\n proc_do_cad_pid+0x190/0x1b0 kernel/sysctl.c:1401\n proc_sys_call_handler+0x338/0x4b0 fs/proc/proc_sysctl.c:591\n proc_sys_write+0x34/0x48 fs/proc/proc_sysctl.c:617\n call_write_iter include/linux/fs.h:1977 [inline]\n new_sync_write+0x3ac/0x510 fs/read_write.c:518\n vfs_write fs/read_write.c:605 [inline]\n vfs_write+0x9c4/0x1018 fs/read_write.c:585\n ksys_write+0x124/0x240 fs/read_write.c:658\n __do_sys_write fs/read_write.c:670 [inline]\n __se_sys_write fs/read_write.c:667 [inline]\n __arm64_sys_write+0x78/0xb0 fs/read_write.c:667\n __invoke_syscall arch/arm64/kernel/syscall.c:37 [inline]\n invoke_syscall arch/arm64/kernel/syscall.c:49 [inline]\n el0_svc_common.constprop.1+0x16c/0x388 arch/arm64/kernel/syscall.c:129\n do_el0_svc+0xf8/0x150 arch/arm64/kernel/syscall.c:168\n el0_svc+0x28/0x38 arch/arm64/kernel/entry-common.c:416\n el0_sync_handler+0x134/0x180 arch/arm64/kernel/entry-common.c:432\n el0_sync+0x154/0x180 arch/arm64/kernel/entry.S:701\n\n The buggy address belongs to the object at ffff23794dda0000\n which belongs to the cache pid of size 224\n The buggy address is located 4 bytes inside of\n 224-byte region [ff\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: sc16is7xx: convert from _raw_ to _noinc_ regmap functions for FIFO
The SC16IS7XX IC supports a burst mode to access the FIFOs where the
initial register address is sent ($00), followed by all the FIFO data
without having to resend the register address each time. In this mode, the
IC doesn't increment the register address for each R/W byte.
The regmap_raw_read() and regmap_raw_write() are functions which can
perform IO over multiple registers. They are currently used to read/write
from/to the FIFO, and although they operate correctly in this burst mode on
the SPI bus, they would corrupt the regmap cache if it was not disabled
manually. The reason is that when the R/W size is more than 1 byte, these
functions assume that the register address is incremented and handle the
cache accordingly.
Convert FIFO R/W functions to use the regmap _noinc_ versions in order to
remove the manual cache control which was a workaround when using the
_raw_ versions. FIFO registers are properly declared as volatile so
cache will not be used/updated for FIFO accesses.

In this mode, the\nIC doesn\u0027t increment the register address for each R/W byte.\n\nThe regmap_raw_read() and regmap_raw_write() are functions which can\nperform IO over multiple registers. They are currently used to read/write\nfrom/to the FIFO, and although they operate correctly in this burst mode on\nthe SPI bus, they would corrupt the regmap cache if it was not disabled\nmanually. The reason is that when the R/W size is more than 1 byte, these\nfunctions assume that the register address is incremented and handle the\ncache accordingly.\n\nConvert FIFO R/W functions to use the regmap _noinc_ versions in order to\nremove the manual cache control which was a workaround when using the\n_raw_ versions. FIFO registers are properly declared as volatile so\ncache will not be used/updated for FIFO accesses."

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: sunxi-ng: Unregister clocks/resets when unbinding
Currently, unbinding a CCU driver unmaps the device's MMIO region, while
leaving its clocks/resets and their providers registered. This can cause
a page fault later when some clock operation tries to perform MMIO. Fix
this by separating the CCU initialization from the memory allocation,
and then using a devres callback to unregister the clocks and resets.
This also fixes a memory leak of the `struct ccu_reset`, and uses the
correct owner (the specific platform driver) for the clocks and resets.
Early OF clock providers are never unregistered, and limited error
handling is possible, so they are mostly unchanged. The error reporting
is made more consistent by moving the message inside of_sunxi_ccu_probe.

This can cause\na page fault later when some clock operation tries to perform MMIO. Fix\nthis by separating the CCU initialization from the memory allocation,\nand then using a devres callback to unregister the clocks and resets.\n\nThis also fixes a memory leak of the `struct ccu_reset`, and uses the\ncorrect owner (the specific platform driver) for the clocks and resets.\n\nEarly OF clock providers are never unregistered, and limited error\nhandling is possible, so they are mostly unchanged. The error reporting\nis made more consistent by moving the message inside of_sunxi_ccu_probe."

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSv4: Fix a NULL pointer dereference in pnfs_mark_matching_lsegs_return()
Commit de144ff4234f changes _pnfs_return_layout() to call
pnfs_mark_matching_lsegs_return() passing NULL as the struct
pnfs_layout_range argument. Unfortunately,
pnfs_mark_matching_lsegs_return() doesn't check if we have a value here
before dereferencing it, causing an oops.
I'm able to hit this crash consistently when running connectathon basic
tests on NFS v4.1/v4.2 against Ontap.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: usbtv: Remove useless locks in usbtv_video_free()
Remove locks calls in usbtv_video_free() because
are useless and may led to a deadlock as reported here:
https://syzkaller.appspot.com/x/bisect.txt?x=166dc872180000
Also remove usbtv_stop() call since it will be called when
unregistering the device.
Before 'c838530d230b' this issue would only be noticed if you
disconnect while streaming and now it is noticeable even when
disconnecting while not streaming.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm: bridge/panel: Cleanup connector on bridge detach
If we don't call drm_connector_cleanup() manually in
panel_bridge_detach(), the connector will be cleaned up with the other
DRM objects in the call to drm_mode_config_cleanup(). However, since our
drm_connector is devm-allocated, by the time drm_mode_config_cleanup()
will be called, our connector will be long gone. Therefore, the
connector must be cleaned up when the bridge is detached to avoid
use-after-free conditions.
v2: Cleanup connector only if it was created
v3: Add FIXME
v4: (Use connector->dev) directly in if() block

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: rfcomm: Fix null-ptr-deref in rfcomm_check_security
During our fuzz testing of the connection and disconnection process at the
RFCOMM layer, we discovered this bug. By comparing the packets from a
normal connection and disconnection process with the testcase that
triggered a KASAN report. We analyzed the cause of this bug as follows:
1. In the packets captured during a normal connection, the host sends a
`Read Encryption Key Size` type of `HCI_CMD` packet
(Command Opcode: 0x1408) to the controller to inquire the length of
encryption key.After receiving this packet, the controller immediately
replies with a Command Completepacket (Event Code: 0x0e) to return the
Encryption Key Size.
2. In our fuzz test case, the timing of the controller's response to this
packet was delayed to an unexpected point: after the RFCOMM and L2CAP
layers had disconnected but before the HCI layer had disconnected.
3. After receiving the Encryption Key Size Response at the time described
in point 2, the host still called the rfcomm_check_security function.
However, by this time `struct l2cap_conn *conn = l2cap_pi(sk)->chan->conn;`
had already been released, and when the function executed
`return hci_conn_security(conn->hcon, d->sec_level, auth_type, d->out);`,
specifically when accessing `conn->hcon`, a null-ptr-deref error occurred.
To fix this bug, check if `sk->sk_state` is BT_CLOSED before calling
rfcomm_recv_frame in rfcomm_process_rx.

By comparing the packets from a\nnormal connection and disconnection process with the testcase that\ntriggered a KASAN report. We analyzed the cause of this bug as follows:\n\n1. In the packets captured during a normal connection, the host sends a\n`Read Encryption Key Size` type of `HCI_CMD` packet\n(Command Opcode: 0x1408) to the controller to inquire the length of\nencryption key.After receiving this packet, the controller immediately\nreplies with a Command Completepacket (Event Code: 0x0e) to return the\nEncryption Key Size.\n\n2. In our fuzz test case, the timing of the controller\u0027s response to this\npacket was delayed to an unexpected point: after the RFCOMM and L2CAP\nlayers had disconnected but before the HCI layer had disconnected.\n\n3. After receiving the Encryption Key Size Response at the time described\nin point 2, the host still called the rfcomm_check_security function.\nHowever, by this time `struct l2cap_conn *conn = l2cap_pi(sk)-\u003echan-\u003econn;`\nhad already been released, and when the function executed\n`return hci_conn_security(conn-\u003ehcon, d-\u003esec_level, auth_type, d-\u003eout);`,\nspecifically when accessing `conn-\u003ehcon`, a null-ptr-deref error occurred.\n\nTo fix this bug, check if `sk-\u003esk_state` is BT_CLOSED before calling\nrfcomm_recv_frame in rfcomm_process_rx."

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: Stop looking for coalesced MMIO zones if the bus is destroyed
Abort the walk of coalesced MMIO zones if kvm_io_bus_unregister_dev()
fails to allocate memory for the new instance of the bus. If it can't
instantiate a new bus, unregister_dev() destroys all devices _except_ the
target device. But, it doesn't tell the caller that it obliterated the
bus and invoked the destructor for all devices that were on the bus. In
the coalesced MMIO case, this can result in a deleted list entry
dereference due to attempting to continue iterating on coalesced_zones
after future entries (in the walk) have been deleted.
Opportunistically add curly braces to the for-loop, which encompasses
many lines but sneaks by without braces due to the guts being a single
if statement.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/64s: Fix pte update for kernel memory on radix
When adding a PTE a ptesync is needed to order the update of the PTE
with subsequent accesses otherwise a spurious fault may be raised.
radix__set_pte_at() does not do this for performance gains. For
non-kernel memory this is not an issue as any faults of this kind are
corrected by the page fault handler. For kernel memory these faults
are not handled. The current solution is that there is a ptesync in
flush_cache_vmap() which should be called when mapping from the
vmalloc region.
However, map_kernel_page() does not call flush_cache_vmap(). This is
troublesome in particular for code patching with Strict RWX on radix.
In do_patch_instruction() the page frame that contains the instruction
to be patched is mapped and then immediately patched. With no ordering
or synchronization between setting up the PTE and writing to the page
it is possible for faults.
As the code patching is done using __put_user_asm_goto() the resulting
fault is obscured - but using a normal store instead it can be seen:
BUG: Unable to handle kernel data access on write at 0xc008000008f24a3c

https://lore.kernel.org/linuxppc-dev/15AC5B0E-A221-4B8C-9039-FA96B8EF7C88@lca.pw/
Chris Riedl suggested a reliable way to reproduce the issue:
$ mount -t debugfs none /sys/kernel/debug
$ (while true; do echo function > /sys/kernel/debug/tracing/current_tracer ; echo nop > /sys/kernel/debug/tracing/current_tracer ; done) &
Turning ftrace on and off does a large amount of code patching which
in usually less then 5min will crash giving a trace like:

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\npowerpc/64s: Fix pte update for kernel memory on radix\n\nWhen adding a PTE a ptesync is needed to order the update of the PTE\nwith subsequent accesses otherwise a spurious fault may be raised.\n\nradix__set_pte_at() does not do this for performance gains. For\nnon-kernel memory this is not an issue as any faults of this kind are\ncorrected by the page fault handler. For kernel memory these faults\nare not handled. The current solution is that there is a ptesync in\nflush_cache_vmap() which should be called when mapping from the\nvmalloc region.\n\nHowever, map_kernel_page() does not call flush_cache_vmap(). This is\ntroublesome in particular for code patching with Strict RWX on radix.\nIn do_patch_instruction() the page frame that contains the instruction\nto be patched is mapped and then immediately patched. With no ordering\nor synchronization between setting up the PTE and writing to the page\nit is possible for faults.\n\nAs the code patching is done using __put_user_asm_goto() the resulting\nfault is obscured - but using a normal store instead it can be seen:\n\n BUG: Unable to handle kernel data access on write at 0xc008000008f24a3c\n Faulting instruction address: 0xc00000000008bd74\n Oops: Kernel access of bad area, sig: 11 [#1]\n LE PAGE_SIZE=64K MMU=Radix SMP NR_CPUS=2048 NUMA PowerNV\n Modules linked in: nop_module(PO+) [last unloaded: nop_module]\n CPU: 4 PID: 757 Comm: sh Tainted: P O 5.10.0-rc5-01361-ge3c1b78c8440-dirty #43\n NIP: c00000000008bd74 LR: c00000000008bd50 CTR: c000000000025810\n REGS: c000000016f634a0 TRAP: 0300 Tainted: P O (5.10.0-rc5-01361-ge3c1b78c8440-dirty)\n MSR: 9000000000009033 \u003cSF,HV,EE,ME,IR,DR,RI,LE\u003e CR: 44002884 XER: 00000000\n CFAR: c00000000007c68c DAR: c008000008f24a3c DSISR: 42000000 IRQMASK: 1\n\nThis results in the kind of issue reported here:\n https://lore.kernel.org/linuxppc-dev/15AC5B0E-A221-4B8C-9039-FA96B8EF7C88@lca.pw/\n\nChris Riedl suggested a reliable way to reproduce the issue:\n $ mount -t debugfs none /sys/kernel/debug\n $ (while true; do echo function \u003e /sys/kernel/debug/tracing/current_tracer ; echo nop \u003e /sys/kernel/debug/tracing/current_tracer ; done) \u0026\n\nTurning ftrace on and off does a large amount of code patching which\nin usually less then 5min will crash giving a trace like:\n\n ftrace-powerpc: (____ptrval____): replaced (4b473b11) != old (60000000)\n ------------[ ftrace bug ]------------\n ftrace failed to modify\n [\u003cc000000000bf8e5c\u003e] napi_busy_loop+0xc/0x390\n actual: 11:3b:47:4b\n Setting ftrace call site to call ftrace function\n ftrace record flags: 80000001\n (1)\n expected tramp: c00000000006c96c\n ------------[ cut here ]------------\n WARNING: CPU: 4 PID: 809 at kernel/trace/ftrace.c:2065 ftrace_bug+0x28c/0x2e8\n Modules linked in: nop_module(PO-) [last unloaded: nop_module]\n CPU: 4 PID: 809 Comm: sh Tainted: P O 5.10.0-rc5-01360-gf878ccaf250a #1\n NIP: c00000000024f334 LR: c00000000024f330 CTR: c0000000001a5af0\n REGS: c000000004c8b760 TRAP: 0700 Tainted: P O (5.10.0-rc5-01360-gf878ccaf250a)\n MSR: 900000000282b033 \u003cSF,HV,VEC,VSX,EE,FP,ME,IR,DR,RI,LE\u003e CR: 28008848 XER: 20040000\n CFAR: c0000000001a9c98 IRQMASK: 0\n GPR00: c00000000024f330 c000000004c8b9f0 c000000002770600 0000000000000022\n GPR04: 00000000ffff7fff c000000004c8b6d0 0000000000000027 c0000007fe9bcdd8\n GPR08: 0000000000000023 ffffffffffffffd8 0000000000000027 c000000002613118\n GPR12: 0000000000008000 c0000007fffdca00 0000000000000000 0000000000000000\n GPR16: 0000000023ec37c5 0000000000000000 0000000000000000 0000000000000008\n GPR20: c000000004c8bc90 c0000000027a2d20 c000000004c8bcd0 c000000002612fe8\n GPR24: 0000000000000038 0000000000000030 0000000000000028 0000000000000020\n GPR28: c000000000ff1b68 c000000000bf8e5c c00000000312f700 c000000000fbb9b0\n NIP ftrace_bug+0x28c/0x2e8\n LR ftrace_bug+0x288/0x2e8\n Call T\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: sr: fix out-of-bounds read when setting HMAC data.
The SRv6 layer allows defining HMAC data that can later be used to sign IPv6
Segment Routing Headers. This configuration is realised via netlink through
four attributes: SEG6_ATTR_HMACKEYID, SEG6_ATTR_SECRET, SEG6_ATTR_SECRETLEN and
SEG6_ATTR_ALGID. Because the SECRETLEN attribute is decoupled from the actual
length of the SECRET attribute, it is possible to provide invalid combinations
(e.g., secret = "", secretlen = 64). This case is not checked in the code and
with an appropriately crafted netlink message, an out-of-bounds read of up
to 64 bytes (max secret length) can occur past the skb end pointer and into
skb_shared_info:

The OOB data can then be read back from userspace by dumping HMAC state. This
commit fixes this by ensuring SECRETLEN cannot exceed the actual length of
SECRET.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/hyperv: Fix NULL deref in set_hv_tscchange_cb() if Hyper-V setup fails
Check for a valid hv_vp_index array prior to derefencing hv_vp_index when
setting Hyper-V's TSC change callback. If Hyper-V setup failed in
hyperv_init(), the kernel will still report that it's running under
Hyper-V, but will have silently disabled nearly all functionality.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - ADF_STATUS_PF_RUNNING should be set after adf_dev_init
ADF_STATUS_PF_RUNNING is (only) used and checked by adf_vf2pf_shutdown()
before calling adf_iov_putmsg()->mutex_lock(vf2pf_lock), however the
vf2pf_lock is initialized in adf_dev_init(), which can fail and when it
fail, the vf2pf_lock is either not initialized or destroyed, a subsequent
use of vf2pf_lock will cause issue.
To fix this issue, only set this flag if adf_dev_init() returns 0.

Summary
In the Linux kernel, the following vulnerability has been resolved:
geneve: make sure to pull inner header in geneve_rx()
syzbot triggered a bug in geneve_rx() [1]
Issue is similar to the one I fixed in commit 8d975c15c0cd
("ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()")
We have to save skb->network_header in a temporary variable
in order to be able to recompute the network_header pointer
after a pskb_inet_may_pull() call.
pskb_inet_may_pull() makes sure the needed headers are in skb->head.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: Destroy I/O bus devices on unregister failure _after_ sync'ing SRCU
If allocating a new instance of an I/O bus fails when unregistering a
device, wait to destroy the device until after all readers are guaranteed
to see the new null bus. Destroying devices before the bus is nullified
could lead to use-after-free since readers expect the devices on their
reference of the bus to remain valid.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm: Don't unref the same fb many times by mistake due to deadlock handling
If we get a deadlock after the fb lookup in drm_mode_page_flip_ioctl()
we proceed to unref the fb and then retry the whole thing from the top.
But we forget to reset the fb pointer back to NULL, and so if we then
get another error during the retry, before the fb lookup, we proceed
the unref the same fb again without having gotten another reference.
The end result is that the fb will (eventually) end up being freed
while it's still in use.
Reset fb to NULL once we've unreffed it to avoid doing it again
until we've done another fb lookup.
This turned out to be pretty easy to hit on a DG2 when doing async
flips (and CONFIG_DEBUG_WW_MUTEX_SLOWPATH=y). The first symptom I
saw that drm_closefb() simply got stuck in a busy loop while walking
the framebuffer list. Fortunately I was able to convince it to oops
instead, and from there it was easier to track down the culprit.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netlink: Fix kernel-infoleak-after-free in __skb_datagram_iter
syzbot reported the following uninit-value access issue [1]:
netlink_to_full_skb() creates a new `skb` and puts the `skb->data`
passed as a 1st arg of netlink_to_full_skb() onto new `skb`. The data
size is specified as `len` and passed to skb_put_data(). This `len`
is based on `skb->end` that is not data offset but buffer offset. The
`skb->end` contains data and tailroom. Since the tailroom is not
initialized when the new `skb` created, KMSAN detects uninitialized
memory area when copying the data.
This patch resolved this issue by correct the len from `skb->end` to
`skb->len`, which is the actual data offset.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnetlink: Fix kernel-infoleak-after-free in __skb_datagram_iter\n\nsyzbot reported the following uninit-value access issue [1]:\n\nnetlink_to_full_skb() creates a new `skb` and puts the `skb-\u003edata`\npassed as a 1st arg of netlink_to_full_skb() onto new `skb`. The data\nsize is specified as `len` and passed to skb_put_data(). This `len`\nis based on `skb-\u003eend` that is not data offset but buffer offset. The\n`skb-\u003eend` contains data and tailroom. Since the tailroom is not\ninitialized when the new `skb` created, KMSAN detects uninitialized\nmemory area when copying the data.\n\nThis patch resolved this issue by correct the len from `skb-\u003eend` to\n`skb-\u003elen`, which is the actual data offset.\n\nBUG: KMSAN: kernel-infoleak-after-free in instrument_copy_to_user include/linux/instrumented.h:114 [inline]\nBUG: KMSAN: kernel-infoleak-after-free in copy_to_user_iter lib/iov_iter.c:24 [inline]\nBUG: KMSAN: kernel-infoleak-after-free in iterate_ubuf include/linux/iov_iter.h:29 [inline]\nBUG: KMSAN: kernel-infoleak-after-free in iterate_and_advance2 include/linux/iov_iter.h:245 [inline]\nBUG: KMSAN: kernel-infoleak-after-free in iterate_and_advance include/linux/iov_iter.h:271 [inline]\nBUG: KMSAN: kernel-infoleak-after-free in _copy_to_iter+0x364/0x2520 lib/iov_iter.c:186\n instrument_copy_to_user include/linux/instrumented.h:114 [inline]\n copy_to_user_iter lib/iov_iter.c:24 [inline]\n iterate_ubuf include/linux/iov_iter.h:29 [inline]\n iterate_and_advance2 include/linux/iov_iter.h:245 [inline]\n iterate_and_advance include/linux/iov_iter.h:271 [inline]\n _copy_to_iter+0x364/0x2520 lib/iov_iter.c:186\n copy_to_iter include/linux/uio.h:197 [inline]\n simple_copy_to_iter+0x68/0xa0 net/core/datagram.c:532\n __skb_datagram_iter+0x123/0xdc0 net/core/datagram.c:420\n skb_copy_datagram_iter+0x5c/0x200 net/core/datagram.c:546\n skb_copy_datagram_msg include/linux/skbuff.h:3960 [inline]\n packet_recvmsg+0xd9c/0x2000 net/packet/af_packet.c:3482\n sock_recvmsg_nosec net/socket.c:1044 [inline]\n sock_recvmsg net/socket.c:1066 [inline]\n sock_read_iter+0x467/0x580 net/socket.c:1136\n call_read_iter include/linux/fs.h:2014 [inline]\n new_sync_read fs/read_write.c:389 [inline]\n vfs_read+0x8f6/0xe00 fs/read_write.c:470\n ksys_read+0x20f/0x4c0 fs/read_write.c:613\n __do_sys_read fs/read_write.c:623 [inline]\n __se_sys_read fs/read_write.c:621 [inline]\n __x64_sys_read+0x93/0xd0 fs/read_write.c:621\n do_syscall_x64 arch/x86/entry/common.c:52 [inline]\n do_syscall_64+0x44/0x110 arch/x86/entry/common.c:83\n entry_SYSCALL_64_after_hwframe+0x63/0x6b\n\nUninit was stored to memory at:\n skb_put_data include/linux/skbuff.h:2622 [inline]\n netlink_to_full_skb net/netlink/af_netlink.c:181 [inline]\n __netlink_deliver_tap_skb net/netlink/af_netlink.c:298 [inline]\n __netlink_deliver_tap+0x5be/0xc90 net/netlink/af_netlink.c:325\n netlink_deliver_tap net/netlink/af_netlink.c:338 [inline]\n netlink_deliver_tap_kernel net/netlink/af_netlink.c:347 [inline]\n netlink_unicast_kernel net/netlink/af_netlink.c:1341 [inline]\n netlink_unicast+0x10f1/0x1250 net/netlink/af_netlink.c:1368\n netlink_sendmsg+0x1238/0x13d0 net/netlink/af_netlink.c:1910\n sock_sendmsg_nosec net/socket.c:730 [inline]\n __sock_sendmsg net/socket.c:745 [inline]\n ____sys_sendmsg+0x9c2/0xd60 net/socket.c:2584\n ___sys_sendmsg+0x28d/0x3c0 net/socket.c:2638\n __sys_sendmsg net/socket.c:2667 [inline]\n __do_sys_sendmsg net/socket.c:2676 [inline]\n __se_sys_sendmsg net/socket.c:2674 [inline]\n __x64_sys_sendmsg+0x307/0x490 net/socket.c:2674\n do_syscall_x64 arch/x86/entry/common.c:52 [inline]\n do_syscall_64+0x44/0x110 arch/x86/entry/common.c:83\n entry_SYSCALL_64_after_hwframe+0x63/0x6b\n\nUninit was created at:\n free_pages_prepare mm/page_alloc.c:1087 [inline]\n free_unref_page_prepare+0xb0/0xa40 mm/page_alloc.c:2347\n free_unref_page_list+0xeb/0x1100 mm/page_alloc.c:2533\n release_pages+0x23d3/0x2410 mm/swap.c:1042\n free_pages_and_swap_cache+0xd9/0xf0 mm/swap_state.c:316\n tlb_batch_pages\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: b43: Stop/wake correct queue in DMA Tx path when QoS is disabled
When QoS is disabled, the queue priority value will not map to the correct
ieee80211 queue since there is only one queue. Stop/wake queue 0 when QoS
is disabled to prevent trying to stop/wake a non-existent queue and failing
to stop/wake the actual queue instantiated.
Log of issue before change (with kernel parameter qos=0):

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: custom_method: fix potential use-after-free issue
In cm_write(), buf is always freed when reaching the end of the
function. If the requested count is less than table.length, the
allocated buffer will be freed but subsequent calls to cm_write() will
still try to access it.
Remove the unconditional kfree(buf) at the end of the function and
set the buf to NULL in the -EINVAL error path to match the rest of
function.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/nfc: fix use-after-free llcp_sock_bind/connect
Commits 8a4cd82d ("nfc: fix refcount leak in llcp_sock_connect()")
and c33b1cc62 ("nfc: fix refcount leak in llcp_sock_bind()")
fixed a refcount leak bug in bind/connect but introduced a
use-after-free if the same local is assigned to 2 different sockets.
This can be triggered by the following simple program:
int sock1 = socket( AF_NFC, SOCK_STREAM, NFC_SOCKPROTO_LLCP );
int sock2 = socket( AF_NFC, SOCK_STREAM, NFC_SOCKPROTO_LLCP );
memset( &addr, 0, sizeof(struct sockaddr_nfc_llcp) );
addr.sa_family = AF_NFC;
addr.nfc_protocol = NFC_PROTO_NFC_DEP;
bind( sock1, (struct sockaddr*) &addr, sizeof(struct sockaddr_nfc_llcp) )
bind( sock2, (struct sockaddr*) &addr, sizeof(struct sockaddr_nfc_llcp) )
close(sock1);
close(sock2);
Fix this by assigning NULL to llcp_sock->local after calling
nfc_llcp_local_put.
This addresses CVE-2021-23134.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: fix race condition on enabling fast-xmit
fast-xmit must only be enabled after the sta has been uploaded to the driver,
otherwise it could end up passing the not-yet-uploaded sta via drv_tx calls
to the driver, leading to potential crashes because of uninitialized drv_priv
data.
Add a missing sta->uploaded check and re-check fast xmit after inserting a sta.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: roles: fix NULL pointer issue when put module's reference
In current design, usb role class driver will get usb_role_switch parent's
module reference after the user get usb_role_switch device and put the
reference after the user put the usb_role_switch device. However, the
parent device of usb_role_switch may be removed before the user put the
usb_role_switch. If so, then, NULL pointer issue will be met when the user
put the parent module's reference.
This will save the module pointer in structure of usb_role_switch. Then,
we don't need to find module by iterating long relations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: act_mirred: don't override retval if we already lost the skb
If we're redirecting the skb, and haven't called tcf_mirred_forward(),
yet, we need to tell the core to drop the skb by setting the retcode
to SHOT. If we have called tcf_mirred_forward(), however, the skb
is out of our hands and returning SHOT will lead to UaF.
Move the retval override to the error path which actually need it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
arp: Prevent overflow in arp_req_get().
syzkaller reported an overflown write in arp_req_get(). [0]
When ioctl(SIOCGARP) is issued, arp_req_get() looks up an neighbour
entry and copies neigh->ha to struct arpreq.arp_ha.sa_data.
The arp_ha here is struct sockaddr, not struct sockaddr_storage, so
the sa_data buffer is just 14 bytes.
In the splat below, 2 bytes are overflown to the next int field,
arp_flags. We initialise the field just after the memcpy(), so it's
not a problem.
However, when dev->addr_len is greater than 22 (e.g. MAX_ADDR_LEN),
arp_netmask is overwritten, which could be set as htonl(0xFFFFFFFFUL)
in arp_ioctl() before calling arp_req_get().
To avoid the overflow, let's limit the max length of memcpy().
Note that commit b5f0de6df6dc ("net: dev: Convert sa_data to flexible
array in struct sockaddr") just silenced syzkaller.

memcpy: detected field-spanning write (size 16) of single field "r->arp_ha.sa_data" at net/ipv4/arp.c:1128 (size 14)

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ice: Fix potential NULL pointer dereference in ice_bridge_setlink()
The function ice_bridge_setlink() may encounter a NULL pointer dereference
if nlmsg_find_attr() returns NULL and br_spec is dereferenced subsequently
in nla_for_each_nested(). To address this issue, add a check to ensure that
br_spec is not NULL before proceeding with the nested attribute iteration.

Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/hfi1: Fix bugs with non-PAGE_SIZE-end multi-iovec user SDMA requests
hfi1 user SDMA request processing has two bugs that can cause data
corruption for user SDMA requests that have multiple payload iovecs
where an iovec other than the tail iovec does not run up to the page
boundary for the buffer pointed to by that iovec.a
Here are the specific bugs:
1. user_sdma_txadd() does not use struct user_sdma_iovec->iov.iov_len.
Rather, user_sdma_txadd() will add up to PAGE_SIZE bytes from iovec
to the packet, even if some of those bytes are past
iovec->iov.iov_len and are thus not intended to be in the packet.
2. user_sdma_txadd() and user_sdma_send_pkts() fail to advance to the
next iovec in user_sdma_request->iovs when the current iovec
is not PAGE_SIZE and does not contain enough data to complete the
packet. The transmitted packet will contain the wrong data from the
iovec pages.
This has not been an issue with SDMA packets from hfi1 Verbs or PSM2
because they only produce iovecs that end short of PAGE_SIZE as the tail
iovec of an SDMA request.
Fixing these bugs exposes other bugs with the SDMA pin cache
(struct mmu_rb_handler) that get in way of supporting user SDMA requests
with multiple payload iovecs whose buffers do not end at PAGE_SIZE. So
this commit fixes those issues as well.
Here are the mmu_rb_handler bugs that non-PAGE_SIZE-end multi-iovec
payload user SDMA requests can hit:
1. Overlapping memory ranges in mmu_rb_handler will result in duplicate
pinnings.
2. When extending an existing mmu_rb_handler entry (struct mmu_rb_node),
the mmu_rb code (1) removes the existing entry under a lock, (2)
releases that lock, pins the new pages, (3) then reacquires the lock
to insert the extended mmu_rb_node.
If someone else comes in and inserts an overlapping entry between (2)
and (3), insert in (3) will fail.
The failure path code in this case unpins _all_ pages in either the
original mmu_rb_node or the new mmu_rb_node that was inserted between
(2) and (3).
3. In hfi1_mmu_rb_remove_unless_exact(), mmu_rb_node->refcount is
incremented outside of mmu_rb_handler->lock. As a result, mmu_rb_node
could be evicted by another thread that gets mmu_rb_handler->lock and
checks mmu_rb_node->refcount before mmu_rb_node->refcount is
incremented.
4. Related to #2 above, SDMA request submission failure path does not
check mmu_rb_node->refcount before freeing mmu_rb_node object.
If there are other SDMA requests in progress whose iovecs have
pointers to the now-freed mmu_rb_node(s), those pointers to the
now-freed mmu_rb nodes will be dereferenced when those SDMA requests
complete.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: dvb-frontends: avoid stack overflow warnings with clang
A previous patch worked around a KASAN issue in stv0367, now a similar
problem showed up with clang:
drivers/media/dvb-frontends/stv0367.c:1222:12: error: stack frame size (3624) exceeds limit (2048) in 'stv0367ter_set_frontend' [-Werror,-Wframe-larger-than]
1214 | static int stv0367ter_set_frontend(struct dvb_frontend *fe)
Rework the stv0367_writereg() function to be simpler and mark both
register access functions as noinline_for_stack so the temporary
i2c_msg structures do not get duplicated on the stack when KASAN_STACK
is enabled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Restructure trace_clock_global() to never block
It was reported that a fix to the ring buffer recursion detection would
cause a hung machine when performing suspend / resume testing. The
following backtrace was extracted from debugging that case:
Call Trace:
trace_clock_global+0x91/0xa0
__rb_reserve_next+0x237/0x460
ring_buffer_lock_reserve+0x12a/0x3f0
trace_buffer_lock_reserve+0x10/0x50
__trace_graph_return+0x1f/0x80
trace_graph_return+0xb7/0xf0
? trace_clock_global+0x91/0xa0
ftrace_return_to_handler+0x8b/0xf0
? pv_hash+0xa0/0xa0
return_to_handler+0x15/0x30
? ftrace_graph_caller+0xa0/0xa0
? trace_clock_global+0x91/0xa0
? __rb_reserve_next+0x237/0x460
? ring_buffer_lock_reserve+0x12a/0x3f0
? trace_event_buffer_lock_reserve+0x3c/0x120
? trace_event_buffer_reserve+0x6b/0xc0
? trace_event_raw_event_device_pm_callback_start+0x125/0x2d0
? dpm_run_callback+0x3b/0xc0
? pm_ops_is_empty+0x50/0x50
? platform_get_irq_byname_optional+0x90/0x90
? trace_device_pm_callback_start+0x82/0xd0
? dpm_run_callback+0x49/0xc0
With the following RIP:
RIP: 0010:native_queued_spin_lock_slowpath+0x69/0x200
Since the fix to the recursion detection would allow a single recursion to
happen while tracing, this lead to the trace_clock_global() taking a spin
lock and then trying to take it again:
ring_buffer_lock_reserve() {
trace_clock_global() {
arch_spin_lock() {
queued_spin_lock_slowpath() {
/* lock taken */
(something else gets traced by function graph tracer)
ring_buffer_lock_reserve() {
trace_clock_global() {
arch_spin_lock() {
queued_spin_lock_slowpath() {
/* DEAD LOCK! */
Tracing should *never* block, as it can lead to strange lockups like the
above.
Restructure the trace_clock_global() code to instead of simply taking a
lock to update the recorded "prev_time" simply use it, as two events
happening on two different CPUs that calls this at the same time, really
doesn't matter which one goes first. Use a trylock to grab the lock for
updating the prev_time, and if it fails, simply try again the next time.
If it failed to be taken, that means something else is already updating
it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
moxart: fix potential use-after-free on remove path
It was reported that the mmc host structure could be accessed after it
was freed in moxart_remove(), so fix this by saving the base register of
the device and using it instead of the pointer dereference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix list_add() corruption in lpfc_drain_txq()
When parsing the txq list in lpfc_drain_txq(), the driver attempts to pass
the requests to the adapter. If such an attempt fails, a local "fail_msg"
string is set and a log message output. The job is then added to a
completions list for cancellation.
Processing of any further jobs from the txq list continues, but since
"fail_msg" remains set, jobs are added to the completions list regardless
of whether a wqe was passed to the adapter. If successfully added to
txcmplq, jobs are added to both lists resulting in list corruption.
Fix by clearing the fail_msg string after adding a job to the completions
list. This stops the subsequent jobs from being added to the completions
list unless they had an appropriate failure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
quota: Fix potential NULL pointer dereference
Below race may cause NULL pointer dereference
P1 P2
dquot_free_inode quota_off
drop_dquot_ref
remove_dquot_ref
dquots = i_dquot(inode)
dquots = i_dquot(inode)
srcu_read_lock
dquots[cnt]) != NULL (1)
dquots[type] = NULL (2)
spin_lock(&dquots[cnt]->dq_dqb_lock) (3)
....
If dquot_free_inode(or other routines) checks inode's quota pointers (1)
before quota_off sets it to NULL(2) and use it (3) after that, NULL pointer
dereference will be triggered.
So let's fix it by using a temporary pointer to avoid this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ethernet:enic: Fix a use after free bug in enic_hard_start_xmit
In enic_hard_start_xmit, it calls enic_queue_wq_skb(). Inside
enic_queue_wq_skb, if some error happens, the skb will be freed
by dev_kfree_skb(skb). But the freed skb is still used in
skb_tx_timestamp(skb).
My patch makes enic_queue_wq_skb() return error and goto spin_unlock()
incase of error. The solution is provided by Govind.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: savage: Error out if pixclock equals zero
The userspace program could pass any values to the driver through
ioctl() interface. If the driver doesn't check the value of pixclock,
it may cause divide-by-zero error.
Although pixclock is checked in savagefb_decode_var(), but it is not
checked properly in savagefb_probe(). Fix this by checking whether
pixclock is zero in the function savagefb_check_var() before
info->var.pixclock is used as the divisor.
This is similar to CVE-2022-3061 in i740fb which was fixed by
commit 15cf0b8.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFS: Fix an Oopsable condition in __nfs_pageio_add_request()
Ensure that nfs_pageio_error_cleanup() resets the mirror array contents,
so that the structure reflects the fact that it is now empty.
Also change the test in nfs_pageio_do_add_request() to be more robust by
checking whether or not the list is empty rather than relying on the
value of pg_count.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/kvm: Teardown PV features on boot CPU as well
Various PV features (Async PF, PV EOI, steal time) work through memory
shared with hypervisor and when we restore from hibernation we must
properly teardown all these features to make sure hypervisor doesn't
write to stale locations after we jump to the previously hibernated kernel
(which can try to place anything there). For secondary CPUs the job is
already done by kvm_cpu_down_prepare(), register syscore ops to do
the same for boot CPU.

This issue is caused because usbnet_read_cmd() reads less bytes than requested
(zero byte in the reproducer). In this case, 'buf' is not properly filled.
This patch fixes the issue by returning -ENODATA if usbnet_read_cmd() reads
less bytes than requested.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ARM: footbridge: fix PCI interrupt mapping
Since commit 30fdfb929e82 ("PCI: Add a call to pci_assign_irq() in
pci_device_probe()"), the PCI code will call the IRQ mapping function
whenever a PCI driver is probed. If these are marked as __init, this
causes an oops if a PCI driver is loaded or bound after the kernel has
initialised.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: hso: fix NULL-deref on disconnect regression
Commit 8a12f8836145 ("net: hso: fix null-ptr-deref during tty device
unregistration") fixed the racy minor allocation reported by syzbot, but
introduced an unconditional NULL-pointer dereference on every disconnect
instead.
Specifically, the serial device table must no longer be accessed after
the minor has been released by hso_serial_tty_unregister().

This patch's modification is according to Jan Kara's suggestion in:
https://patchwork.ozlabs.org/project/linux-ext4/patch/20210428085158.3728201-1-yebin10@huawei.com/
"I see. Now I understand your patch. Honestly, seeing how fragile is trying
to fix extent tree after split has failed in the middle, I would probably
go even further and make sure we fix the tree properly in case of ENOSPC
and EDQUOT (those are easily user triggerable). Anything else indicates a
HW problem or fs corruption so I'd rather leave the extent tree as is and
don't try to fix it (which also means we will not create overlapping
extents)."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers/amd/pm: fix a use-after-free in kv_parse_power_table
When ps allocated by kzalloc equals to NULL, kv_parse_power_table
frees adev->pm.dpm.ps that allocated before. However, after the control
flow goes through the following call chains:
kv_parse_power_table
|-> kv_dpm_init
|-> kv_dpm_sw_init
|-> kv_dpm_fini
The adev->pm.dpm.ps is used in the for loop of kv_dpm_fini after its
first free in kv_parse_power_table and causes a use-after-free bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86, relocs: Ignore relocations in .notes section
When building with CONFIG_XEN_PV=y, .text symbols are emitted into
the .notes section so that Xen can find the "startup_xen" entry point.
This information is used prior to booting the kernel, so relocations
are not useful. In fact, performing relocations against the .notes
section means that the KASLR base is exposed since /sys/kernel/notes
is world-readable.
To avoid leaking the KASLR base without breaking unprivileged tools that
are expecting to read /sys/kernel/notes, skip performing relocations in
the .notes section. The values readable in .notes are then identical to
those found in System.map.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mld: fix panic in mld_newpack()
mld_newpack() doesn't allow to allocate high order page,
only order-0 allocation is allowed.
If headroom size is too large, a kernel panic could occur in skb_put().
Test commands:
ip netns del A
ip netns del B
ip netns add A
ip netns add B
ip link add veth0 type veth peer name veth1
ip link set veth0 netns A
ip link set veth1 netns B
ip netns exec A ip link set lo up
ip netns exec A ip link set veth0 up
ip netns exec A ip -6 a a 2001:db8:0::1/64 dev veth0
ip netns exec B ip link set lo up
ip netns exec B ip link set veth1 up
ip netns exec B ip -6 a a 2001:db8:0::2/64 dev veth1
for i in {1..99}
do
let A=$i-1
ip netns exec A ip link add ip6gre$i type ip6gre \
local 2001:db8:$A::1 remote 2001:db8:$A::2 encaplimit 100
ip netns exec A ip -6 a a 2001:db8:$i::1/64 dev ip6gre$i
ip netns exec A ip link set ip6gre$i up
ip netns exec B ip link add ip6gre$i type ip6gre \
local 2001:db8:$A::2 remote 2001:db8:$A::1 encaplimit 100
ip netns exec B ip -6 a a 2001:db8:$i::2/64 dev ip6gre$i
ip netns exec B ip link set ip6gre$i up
done

Summary
In the Linux kernel, the following vulnerability has been resolved:
gve: Add NULL pointer checks when freeing irqs.
When freeing notification blocks, we index priv->msix_vectors.
If we failed to allocate priv->msix_vectors (see abort_with_msix_vectors)
this could lead to a NULL pointer dereference if the driver is unloaded.

Summary
In the Linux kernel, the following vulnerability has been resolved:
uio_hv_generic: Fix a memory leak in error handling paths
If 'vmbus_establish_gpadl()' fails, the (recv|send)_gpadl will not be
updated and 'hv_uio_cleanup()' in the error handling path will not be
able to free the corresponding buffer.
In such a case, we need to free the buffer explicitly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tty: tty_buffer: Fix the softlockup issue in flush_to_ldisc
When running ltp testcase(ltp/testcases/kernel/pty/pty04.c) with arm64, there is a soft lockup,
which look like this one:
Workqueue: events_unbound flush_to_ldisc
Call trace:
dump_backtrace+0x0/0x1ec
show_stack+0x24/0x30
dump_stack+0xd0/0x128
panic+0x15c/0x374

slip_unesc+0x80/0x214 [slip]
tty_ldisc_receive_buf+0x64/0x80
tty_port_default_receive_buf+0x50/0x90
flush_to_ldisc+0xbc/0x110
process_one_work+0x1d4/0x4b0
worker_thread+0x180/0x430
kthread+0x11c/0x120
In the testcase pty04, The first process call the write syscall to send
data to the pty master. At the same time, the workqueue will do the
flush_to_ldisc to pop data in a loop until there is no more data left.
When the sender and workqueue running in different core, the sender sends
data fastly in full time which will result in workqueue doing work in loop
for a long time and occuring softlockup in flush_to_ldisc with kernel
configured without preempt. So I add need_resched check and cond_resched
in the flush_to_ldisc loop to avoid it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i2c: i801: Don't generate an interrupt on bus reset
Now that the i2c-i801 driver supports interrupts, setting the KILL bit
in a attempt to recover from a timed out transaction triggers an
interrupt. Unfortunately, the interrupt handler (i801_isr) is not
prepared for this situation and will try to process the interrupt as
if it was signaling the end of a successful transaction. In the case
of a block transaction, this can result in an out-of-range memory
access.
This condition was reproduced several times by syzbot:
https://syzkaller.appspot.com/bug?extid=ed71512d469895b5b34e
https://syzkaller.appspot.com/bug?extid=8c8dedc0ba9e03f6c79e
https://syzkaller.appspot.com/bug?extid=c8ff0b6d6c73d81b610e
https://syzkaller.appspot.com/bug?extid=33f6c360821c399d69eb
https://syzkaller.appspot.com/bug?extid=be15dc0b1933f04b043a
https://syzkaller.appspot.com/bug?extid=b4d3fd1dfd53e90afd79
So disable interrupts while trying to reset the bus. Interrupts will
be enabled again for the following transaction.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/kvm: Disable kvmclock on all CPUs on shutdown
Currenly, we disable kvmclock from machine_shutdown() hook and this
only happens for boot CPU. We need to disable it for all CPUs to
guard against memory corruption e.g. on restore from hibernate.
Note, writing '0' to kvmclock MSR doesn't clear memory location, it
just prevents hypervisor from updating the location so for the short
while after write and while CPU is still alive, the clock remains usable
and correct so we don't need to switch to some other clocksource.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PM / devfreq: Synchronize devfreq_monitor_[start/stop]
There is a chance if a frequent switch of the governor
done in a loop result in timer list corruption where
timer cancel being done from two place one from
cancel_delayed_work_sync() and followed by expire_timers()
can be seen from the traces[1].
while true
do
echo "simple_ondemand" > /sys/class/devfreq/1d84000.ufshc/governor
echo "performance" > /sys/class/devfreq/1d84000.ufshc/governor
done
It looks to be issue with devfreq driver where
device_monitor_[start/stop] need to synchronized so that
delayed work should get corrupted while it is either
being queued or running or being cancelled.
Let's use polling flag and devfreq lock to synchronize the
queueing the timer instance twice and work data being
corrupted.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ppp_async: limit MRU to 64K
syzbot triggered a warning [1] in __alloc_pages():
WARN_ON_ONCE_GFP(order > MAX_PAGE_ORDER, gfp)
Willem fixed a similar issue in commit c0a2a1b0d631 ("ppp: limit MRU to 64K")
Adopt the same sanity check for ppp_async_ioctl(PPPIOCSMRU)

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: edia: dvbdev: fix a use-after-free
In dvb_register_device, *pdvbdev is set equal to dvbdev, which is freed
in several error-handling paths. However, *pdvbdev is not set to NULL
after dvbdev's deallocation, causing use-after-frees in many places,
for example, in the following call chain:
budget_register
|-> dvb_dmxdev_init
|-> dvb_register_device
|-> dvb_dmxdev_release
|-> dvb_unregister_device
|-> dvb_remove_device
|-> dvb_device_put
|-> kref_put
When calling dvb_unregister_device, dmxdev->dvbdev (i.e. *pdvbdev in
dvb_register_device) could point to memory that had been freed in
dvb_register_device. Thereafter, this pointer is transferred to
kref_put and triggering a use-after-free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvmet-tcp: Fix a kernel panic when host sends an invalid H2C PDU length
If the host sends an H2CData command with an invalid DATAL,
the kernel may crash in nvmet_tcp_build_pdu_iovec().
Unable to handle kernel NULL pointer dereference at
virtual address 0000000000000000
lr : nvmet_tcp_io_work+0x6ac/0x718 [nvmet_tcp]
Call trace:
process_one_work+0x174/0x3c8
worker_thread+0x2d0/0x3e8
kthread+0x104/0x110
Fix the bug by raising a fatal error if DATAL isn't coherent
with the packet size.
Also, the PDU length should never exceed the MAXH2CDATA parameter which
has been communicated to the host in nvmet_tcp_handle_icreq().

Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: Fix NULL ptr dereference on VSI filter sync
Remove the reason of null pointer dereference in sync VSI filters.
Added new I40E_VSI_RELEASING flag to signalize deleting and releasing
of VSI resources to sync this thread with sync filters subtask.
Without this patch it is possible to start update the VSI filter list
after VSI is removed, that's causing a kernel oops.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix data corruption by fallocate
When fallocate punches holes out of inode size, if original isize is in
the middle of last cluster, then the part from isize to the end of the
cluster will be zeroed with buffer write, at that time isize is not yet
updated to match the new size, if writeback is kicked in, it will invoke
ocfs2_writepage()->block_write_full_page() where the pages out of inode
size will be dropped. That will cause file corruption. Fix this by
zero out eof blocks when extending the inode size.
Running the following command with qemu-image 4.2.1 can get a corrupted
coverted image file easily.
qemu-img convert -p -t none -T none -f qcow2 $qcow_image \
-O qcow2 -o compat=1.1 $qcow_image.conv
The usage of fallocate in qemu is like this, it first punches holes out
of inode size, then extend the inode size.
fallocate(11, FALLOC_FL_KEEP_SIZE|FALLOC_FL_PUNCH_HOLE, 2276196352, 65536) = 0
fallocate(11, 0, 2276196352, 65536) = 0

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.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix null pointer dereference in lpfc_prep_els_iocb()
It is possible to call lpfc_issue_els_plogi() passing a did for which no
matching ndlp is found. A call is then made to lpfc_prep_els_iocb() with a
null pointer to a lpfc_nodelist structure resulting in a null pointer
dereference.
Fix by returning an error status if no valid ndlp is found. Fix up comments
regarding ndlp reference counting.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfp: flower: handle acti_netdevs allocation failure
The kmalloc_array() in nfp_fl_lag_do_work() will return null, if
the physical memory has run out. As a result, if we dereference
the acti_netdevs, the null pointer dereference bugs will happen.
This patch adds a check to judge whether allocation failure occurs.
If it happens, the delayed work will be rescheduled and try again.

Summary
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: fix a memleak in gss_import_v2_context
The ctx->mech_used.data allocated by kmemdup is not freed in neither
gss_import_v2_context nor it only caller gss_krb5_import_sec_context,
which frees ctx on error.
Thus, this patch reform the last call of gss_import_v2_context to the
gss_krb5_import_ctx_v2, preventing the memleak while keepping the return
formation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nftables: exthdr: fix 4-byte stack OOB write
If priv->len is a multiple of 4, then dst[len / 4] can write past
the destination array which leads to stack corruption.
This construct is necessary to clean the remainder of the register
in case ->len is NOT a multiple of the register size, so make it
conditional just like nft_payload.c does.
The bug was added in 4.1 cycle and then copied/inherited when
tcp/sctp and ip option support was added.
Bug reported by Zero Day Initiative project (ZDI-CAN-21950,
ZDI-CAN-21951, ZDI-CAN-21961).

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/ptrace: handle setting of fpc register correctly
If the content of the floating point control (fpc) register of a traced
process is modified with the ptrace interface the new value is tested for
validity by temporarily loading it into the fpc register.
This may lead to corruption of the fpc register of the tracing process:
if an interrupt happens while the value is temporarily loaded into the
fpc register, and within interrupt context floating point or vector
registers are used, the current fp/vx registers are saved with
save_fpu_regs() assuming they belong to user space and will be loaded into
fp/vx registers when returning to user space.
test_fp_ctl() restores the original user space fpc register value, however
it will be discarded, when returning to user space.
In result the tracer will incorrectly continue to run with the value that
was supposed to be used for the traced process.
Fix this by saving fpu register contents with save_fpu_regs() before using
test_fp_ctl().

Summary
In the Linux kernel, the following vulnerability has been resolved:
perf/x86/lbr: Filter vsyscall addresses
We found that a panic can occur when a vsyscall is made while LBR sampling
is active. If the vsyscall is interrupted (NMI) for perf sampling, this
call sequence can occur (most recent at top):
__insn_get_emulate_prefix()
insn_get_emulate_prefix()
insn_get_prefixes()
insn_get_opcode()
decode_branch_type()
get_branch_type()
intel_pmu_lbr_filter()
intel_pmu_handle_irq()
perf_event_nmi_handler()
Within __insn_get_emulate_prefix() at frame 0, a macro is called:
peek_nbyte_next(insn_byte_t, insn, i)
Within this macro, this dereference occurs:
(insn)->next_byte
Inspecting registers at this point, the value of the next_byte field is the
address of the vsyscall made, for example the location of the vsyscall
version of gettimeofday() at 0xffffffffff600000. The access to an address
in the vsyscall region will trigger an oops due to an unhandled page fault.
To fix the bug, filtering for vsyscalls can be done when
determining the branch type. This patch will return
a "none" branch if a kernel address if found to lie in the
vsyscall region.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nperf/x86/lbr: Filter vsyscall addresses\n\nWe found that a panic can occur when a vsyscall is made while LBR sampling\nis active. If the vsyscall is interrupted (NMI) for perf sampling, this\ncall sequence can occur (most recent at top):\n\n __insn_get_emulate_prefix()\n insn_get_emulate_prefix()\n insn_get_prefixes()\n insn_get_opcode()\n decode_branch_type()\n get_branch_type()\n intel_pmu_lbr_filter()\n intel_pmu_handle_irq()\n perf_event_nmi_handler()\n\nWithin __insn_get_emulate_prefix() at frame 0, a macro is called:\n\n peek_nbyte_next(insn_byte_t, insn, i)\n\nWithin this macro, this dereference occurs:\n\n (insn)-\u003enext_byte\n\nInspecting registers at this point, the value of the next_byte field is the\naddress of the vsyscall made, for example the location of the vsyscall\nversion of gettimeofday() at 0xffffffffff600000. The access to an address\nin the vsyscall region will trigger an oops due to an unhandled page fault.\n\nTo fix the bug, filtering for vsyscalls can be done when\ndetermining the branch type. This patch will return\na \"none\" branch if a kernel address if found to lie in the\nvsyscall region."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix use-after-free in lpfc_unreg_rpi() routine
An error is detected with the following report when unloading the driver:
"KASAN: use-after-free in lpfc_unreg_rpi+0x1b1b"
The NLP_REG_LOGIN_SEND nlp_flag is set in lpfc_reg_fab_ctrl_node(), but the
flag is not cleared upon completion of the login.
This allows a second call to lpfc_unreg_rpi() to proceed with nlp_rpi set
to LPFC_RPI_ALLOW_ERROR. This results in a use after free access when used
as an rpi_ids array index.
Fix by clearing the NLP_REG_LOGIN_SEND nlp_flag in
lpfc_mbx_cmpl_fc_reg_login().

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix stackmap overflow check on 32-bit arches
The stackmap code relies on roundup_pow_of_two() to compute the number
of hash buckets, and contains an overflow check by checking if the
resulting value is 0. However, on 32-bit arches, the roundup code itself
can overflow by doing a 32-bit left-shift of an unsigned long value,
which is undefined behaviour, so it is not guaranteed to truncate
neatly. This was triggered by syzbot on the DEVMAP_HASH type, which
contains the same check, copied from the hashtab code.
The commit in the fixes tag actually attempted to fix this, but the fix
did not account for the UB, so the fix only works on CPUs where an
overflow does result in a neat truncation to zero, which is not
guaranteed. Checking the value before rounding does not have this
problem.

However, on 32-bit arches, the roundup code itself\ncan overflow by doing a 32-bit left-shift of an unsigned long value,\nwhich is undefined behaviour, so it is not guaranteed to truncate\nneatly. This was triggered by syzbot on the DEVMAP_HASH type, which\ncontains the same check, copied from the hashtab code.\n\nThe commit in the fixes tag actually attempted to fix this, but the fix\ndid not account for the UB, so the fix only works on CPUs where an\noverflow does result in a neat truncation to zero, which is not\nguaranteed. Checking the value before rounding does not have this\nproblem."

Summary
In the Linux kernel, the following vulnerability has been resolved:
cxgb4: avoid accessing registers when clearing filters
Hardware register having the server TID base can contain
invalid values when adapter is in bad state (for example,
due to AER fatal error). Reading these invalid values in the
register can lead to out-of-bound memory access. So, fix
by using the saved server TID base when clearing filters.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ravb: Fix use-after-free issue in ravb_tx_timeout_work()
The ravb_stop() should call cancel_work_sync(). Otherwise,
ravb_tx_timeout_work() is possible to use the freed priv after
ravb_remove() was called like below:
CPU0 CPU1
ravb_tx_timeout()
ravb_remove()
unregister_netdev()
free_netdev(ndev)
// free priv
ravb_tx_timeout_work()
// use priv
unregister_netdev() will call .ndo_stop() so that ravb_stop() is
called. And, after phy_stop() is called, netif_carrier_off()
is also called. So that .ndo_tx_timeout() will not be called
after phy_stop().

Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock/virtio: free queued packets when closing socket
As reported by syzbot [1], there is a memory leak while closing the
socket. We partially solved this issue with commit ac03046ece2b
("vsock/virtio: free packets during the socket release"), but we
forgot to drain the RX queue when the socket is definitely closed by
the scheduled work.
To avoid future issues, let's use the new virtio_transport_remove_sock()
to drain the RX queue before removing the socket from the af_vsock lists
calling vsock_remove_sock().
