🚨 CVE-2026-60122
gpsd through release-3.27.5, fixed at commit 4c06658, contains a code injection vulnerability in the gpsprof utility that allows an attacker who controls GPS input data to execute arbitrary OS commands by injecting malicious content into the SKY.satellites[].used field, which is inserted unsanitized into a gnuplot heredoc data block. Attackers can supply a used value containing the string EOD to terminate the heredoc early and append gnuplot system() calls, achieving OS command execution as the user running gpsprof when the generated plot script is processed by gnuplot in polar mode.

🚨 CVE-2026-65704
FFmpeg through 8.1.2 contains an out-of-bounds write vulnerability that allows attackers to cause heap corruption by supplying a crafted ffconcat file processed with the -safe 0 flag. The TY demuxer's demux_audio() function decrements packet size without bounds checking, producing a negative size value that is passed to memcpy() in shorten_decode_frame(), where conversion to size_t wraps the value to near SIZE_MAX and triggers reads beyond the source allocation and writes far beyond the Shorten decoder's bitstream buffer.

🚨 CVE-2026-65705
FFmpeg versions 3.4 through 8.1.2 contain an out-of-bounds write vulnerability in the vf_floodfill video filter that allows attackers to corrupt heap memory by supplying a dynamically sized video stream with filtergraph reinitialization disabled via -reinit_filter 0. When config_input() allocates the points traversal stack based on initial frame dimensions and a subsequent larger frame is processed, filter_frame() performs flood-fill neighbor pushes beyond the original allocation boundary, resulting in heap corruption and process crash with potential for code execution depending on heap layout and process hardening.

🚨 CVE-2026-65706
FFmpeg versions 3.0 through 8.1.2 contain an out-of-bounds write vulnerability in the vf_swaprect video filter that allows attackers to corrupt heap memory by supplying a crafted NV12 video frame with odd width dimensions. The filter_frame() function reuses a temporary row buffer sized for plane 0's single-byte pixel step across all planes, causing an 18-byte memcpy into a 17-byte heap allocation when processing the two-byte-per-sample interleaved chroma plane of a 17x16 NV12 frame, resulting in heap corruption and process crash with potential for code execution.

🚨 CVE-2026-53120
In the Linux kernel, the following vulnerability has been resolved:

PCI: use generic driver_override infrastructure

When a driver is probed through __driver_attach(), the bus' match()
callback is called without the device lock held, thus accessing the
driver_override field without a lock, which can cause a UAF.

Fix this by using the driver-core driver_override infrastructure taking
care of proper locking internally.

Note that calling match() from __driver_attach() without the device lock
held is intentional. [1]

In the Linux kernel, the following vulnerability has been resolved:

amd-pstate: Fix memory leak in amd_pstate_epp_cpu_init()

On failure to set the epp, the function amd_pstate_epp_cpu_init()
returns with an error code without freeing the cpudata object that was

🚨 CVE-2026-53122
In the Linux kernel, the following vulnerability has been resolved:

btrfs: fix deadlock between reflink and transaction commit when using flushoncommit

When using the flushoncommit mount option, we can have a deadlock between
a transaction commit and a reflink operation that copied an inline extent
to an offset beyond the current i_size of the destination node.

The deadlock happens like this:

1) Task A clones an inline extent from inode X to an offset of inode Y
that is beyond Y's current i_size. This means we copied the inline
extent's data to a folio of inode Y that is beyond its EOF, using a
call to copy_inline_to_page();

2) Task B starts a transaction commit and calls
btrfs_start_delalloc_flush() to flush delalloc;

3) The delalloc flushing sees the new dirty folio of inode Y and when it
attempts to flush it, it ends up at extent_writepage() and sees that
the offset of the folio is beyond the i_size of inode Y, so it attempts
to invalidate the folio by calling folio_invalidate(), which ends up at
btrfs' folio invalidate callback - btrfs_invalidate_folio(). There it
tries to lock the folio's range in inode Y's extent io tree, but it
blocks since it's currently locked by task A - during a reflink we lock
the inodes and the source and destination ranges after flushing all
delalloc and waiting for ordered extent completion - after that we
don't expect to have dirty folios in the ranges, the exception is if
we have to copy an inline extent's data (because the destination offset
is not zero);

4) Task A then attempts to start a transaction to update the inode item,
and then it's blocked since the current transaction is in the
TRANS_STATE_COMMIT_START state. Therefore task A has to wait for the
current transaction to become unblocked (its state >=
TRANS_STATE_UNBLOCKED).

So task A is waiting for the transaction commit done by task B, and
the later waiting on the extent lock of inode Y that is currently
held by task A.

🚨 CVE-2026-53123
In the Linux kernel, the following vulnerability has been resolved:

md: wake raid456 reshape waiters before suspend

During raid456 reshape, direct IO across the reshape position can sleep
in raid5_make_request() waiting for reshape progress while still
holding an active_io reference. If userspace then freezes reshape and
writes md/suspend_lo or md/suspend_hi, mddev_suspend() kills active_io
and waits for all in-flight IO to drain.

This can deadlock: the IO needs reshape progress to continue, but the
reshape thread is already frozen, so the active_io reference is never
dropped and suspend never completes.

raid5_prepare_suspend() already wakes wait_for_reshape for dm-raid. Do
the same for normal md suspend when reshape is already interrupted, so
waiting raid456 IO can abort, drop its reference, and let suspend
finish.

The mdadm test tests/25raid456-reshape-deadlock reproduces the hang.

🚨 CVE-2026-53124
In the Linux kernel, the following vulnerability has been resolved:

ublk: reset per-IO canceled flag on each fetch

If a ublk server starts recovering devices but dies before issuing fetch
commands for all IOs, cancellation of the fetch commands that were
successfully issued may never complete. This is because the per-IO
canceled flag can remain set even after the fetch for that IO has been
submitted - the per-IO canceled flags for all IOs in a queue are reset
together only once all IOs for that queue have been fetched. So if a
nonempty proper subset of the IOs for a queue are fetched when the ublk
server dies, the IOs in that subset will never successfully be canceled,
as their canceled flags remain set, and this prevents ublk_cancel_cmd
from actually calling io_uring_cmd_done on the commands, despite the
fact that they are outstanding.

Fix this by resetting the per-IO cancel flags immediately when each IO
is fetched instead of waiting for all IOs for the queue (which may never
happen).

🚨 CVE-2026-53125
In the Linux kernel, the following vulnerability has been resolved:

md: fix array_state=clear sysfs deadlock

When "clear" is written to array_state, md_attr_store() breaks sysfs
active protection so the array can delete itself from its own sysfs
store method.

However, md_attr_store() currently drops the mddev reference before
calling sysfs_unbreak_active_protection(). Once do_md_stop(..., 0)
has made the mddev eligible for delayed deletion, the temporary
kobject reference taken by sysfs_break_active_protection() can become
the last kobject reference protecting the md kobject.

That allows sysfs_unbreak_active_protection() to drop the last
kobject reference from the current sysfs writer context. kobject
teardown then recurses into kernfs removal while the current sysfs
node is still being unwound, and lockdep reports recursive locking on
kn->active with kernfs_drain() in the call chain.

Reproducer on an existing level:
1. Create an md0 linear array and activate it:
mknod /dev/md0 b 9 0
echo none > /sys/block/md0/md/metadata_version
echo linear > /sys/block/md0/md/level
echo 1 > /sys/block/md0/md/raid_disks
echo "$(cat /sys/class/block/sdb/dev)" > /sys/block/md0/md/new_dev
echo "$(($(cat /sys/class/block/sdb/size) / 2))" > \
/sys/block/md0/md/dev-sdb/size
echo 0 > /sys/block/md0/md/dev-sdb/slot
echo active > /sys/block/md0/md/array_state
2. Wait briefly for the array to settle, then clear it:
sleep 2
echo clear > /sys/block/md0/md/array_state

The warning looks like:

WARNING: possible recursive locking detected
bash/588 is trying to acquire lock:
(kn->active#65) at __kernfs_remove+0x157/0x1d0
but task is already holding lock:

Restore active protection before mddev_put() so the extra sysfs
kobject reference is dropped while the mddev is still held alive. The
actual md kobject deletion is then deferred until after the sysfs
write path has fully returned.

blk-cgroup: fix disk reference leak in blkcg_maybe_throttle_current()

Add the missing put_disk() on the error path in
blkcg_maybe_throttle_current(). When blkcg lookup, blkg lookup, or
blkg_tryget() fails, the function jumps to the out label which only
calls rcu_read_unlock() but does not release the disk reference acquired

this reference either, causing the disk to never be freed.

🚨 CVE-2026-53326
In the Linux kernel, the following vulnerability has been resolved:

debugobjects: Don't call fill_pool() in early boot hardirq context

When booting a debug PREEMPT_RT kernel on an ARM64 system, a "inconsistent
{HARDIRQ-ON-W} -> {IN-HARDIRQ-W} usage" lockdep warning message was
reported to the console.

During early boot, interrupts are enabled before the scheduler is
enabled. In this window (before SYSTEM_SCHEDULING is set) interrupts can
fire and in the hard interrupt context handler attempt to fill the pool

This can lead to a deadlock when the interrupt occurred when the interrupt
hits a region which holds a lock that is required to be taken in the
allocation path.

Add a new can_fill_pool() helper and reorder the exception rule and forbid
this scenario by excluding allocations from hard interrupt context.

scx_cgroup_can_attach() arms cgrp_moving_from only when a task's cpu
cgroup changes. It can still be NULL when scx_cgroup_move_task() runs,
through this sequence:

Step Result
--------------------------------- ----------------------------------
1. cpu enabled on cgroup G cpu css = A
2. cpu toggled off then on for G A killed, B created (same cgroup)
3. an exiting task keeps A alive migration skips it, A now stale
4. +memory migrates G stale A vs current B pulls cpu in
5. cpu attach runs for all tasks hits a live, cpu-unchanged task
6. scx_cgroup_move_task() on it cgrp_moving_from NULL -> WARN

The mismatch is that scx_cgroup_can_attach() keys on cgroup identity
while migration drives the move on css identity, so a NULL cgrp_moving_from
here is a legitimate css-only migration, not a missing prep.

The call is already gated on cgrp_moving_from, so just drop the warning.
ops.cgroup_prep_move() and ops.cgroup_move() stay paired.

bpf: Do not allow deleting local storage in NMI

Currently, local storage may deadlock when deferring freeing selem or
local storage through kfree_rcu(), call_rcu() or call_rcu_tasks_trace()
in NMI or reentrant. Since deleting selem in NMI is an unlikely use
case, partially mitigate it by returning error when calling from
bpf_xxx_storage_delete() helpers in NMI. Note that, it is still possible
to deadlock through reentrant. A full mitigation requires returning
error when irqs_disabled() is true, which, however is too heavy-handed
for bpf_xxx_storage_delete().

The long-term solution requires _nolock versions of call_rcu. Another
possible solution is to defer the free through irq_work [0], but it
would grow the size of selem, which is non-ideal.

The check is only needed in bpf_selem_unlink(), which is used by helpers
and syscalls. bpf_selem_unlink_nofail() is fine as it is called during
map and owner tear down that never run in NMI or reentrant.
