Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: media: amphion: Fix race between m2m
job_abort and device_run Fix kernel panic caused by race condition where v4l2_m2m_ctx_release() frees
m2m_ctx while v4l2_m2m_try_run() is about to call device_run with the same context. Race sequence:
v4l2_m2m_try_run(): v4l2_m2m_ctx_release(): lock/unlock v4l2_m2m_cancel_job() job_abort()
v4l2_m2m_job_finish() kfree(m2m_ctx) <- frees ctx device_run() <- use-after-free crash at 0x538 Crash
trace: Unable to handle kernel read from unreadable memory at virtual address 0000000000000538
v4l2_m2m_try_run+0x78/0x138 v4l2_m2m_device_run_work+0x14/0x20 The amphion vpu driver does not rely on the
m2m framework's device_run callback to perform encode/decode operations. Fix the race by preventing m2m
framework job scheduling entirely: - Add job_ready callback returning 0 (no jobs ready for m2m framework)
- Remove job_abort callback to avoid the race condition (CVE-2026-46058)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
