  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nmedia: amphion: Fix race between m2m job_abort and device_run\nFix kernel panic caused by race condition where v4l2_m2m_ctx_release()\nfrees m2m_ctx while v4l2_m2m_try_run() is about to call device_run\nwith the same context.\nRace sequence:\nv4l2_m2m_try_run():           v4l2_m2m_ctx_release():\nlock/unlock                   v4l2_m2m_cancel_job()\njob_abort()\nv4l2_m2m_job_finish()\nkfree(m2m_ctx)  <- frees ctx\ndevice_run()  <- use-after-free crash at 0x538\nCrash trace:\nUnable to handle kernel read from unreadable memory at virtual address\n0000000000000538\nv4l2_m2m_try_run+0x78/0x138\nv4l2_m2m_device_run_work+0x14/0x20\nThe amphion vpu driver does not rely on the m2m framework's device_run\ncallback to perform encode/decode operations.\nFix the race by preventing m2m framework job scheduling entirely:\n- Add job_ready callback returning 0 (no jobs ready for m2m framework)\n- Remove job_abort callback to avoid the race condition", "A flaw was found in the Linux kernel, specifically within the amphion video processing unit (VPU) driver. A race condition, a situation where multiple operations occur in an unpredictable order, exists in the Video for Linux 2 (V4L2) media-to-memory (m2m) framework. This vulnerability allows a local attacker to exploit a timing issue, leading to a use-after-free error that can cause a kernel panic and result in a denial of service for the system." ],
