  "title": "media: amphion: Fix race between m2m job_abort and device_run",
  "description": "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)  \u003C- frees ctx     device_run()  \u003C- use-after-free crash at 0x538  Crash trace:   Unable to handle kernel read from unreadable memory at virtual address   0000000000000538   v4l2_m2m_try_run\u002B0x78/0x138   v4l2_m2m_device_run_work\u002B0x14/0x20  The amphion vpu driver does not rely on the m2m framework\u0027s 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",
