In the Linux kernel, the following vulnerability has been resolved: media: mediatek: vcodec: fix use-after-free in encoder release path The fops_vcodec_release() function frees the context structure (ctx) without first cancelling any pending or running work in ctx->encode_work. This creates a race window where the workqueue handler (mtk_venc_worker) may still be accessing the context memory after it has been freed. Race condition: CPU 0 (release path) CPU 1 (workqueue) --------------------- ------------------ fops_vcodec_release() v4l2_m2m_ctx_release() v4l2_m2m_cancel_job() // waits for m2m job "done" mtk_venc_worker() v4l2_m2m_job_finish() // m2m job "done" // BUT worker still running! // post-job_finish access: other ctx dereferences // UAF if ctx already freed // returns (job "done") kfree(ctx) // ctx freed Root cause: The v4l2_m2m_ctx_release() only waits for the m2m job lifecycle (via TRANS_RUNNING flag), not the workqueue lifecycle. After v4l2_m2m_job_finish() is called, the m2m framework considers the job complete and v4l2_m2m_ctx_release() returns, but the worker function continues executing and may still access ctx. The work is queued during encode operations via: queue_work(ctx->dev->encode_workqueue, &ctx->encode_work) The worker function accesses ctx->m2m_ctx, ctx->dev, and other ctx fields even after calling v4l2_m2m_job_finish(). This vulnerability was confirmed with KASAN by running an instrumented test module that widens the post-job_finish race window. KASAN detected: BUG: KASAN: slab-use-after-free in mtk_venc_worker+0x159/0x180 Read of size 4 at addr ffff88800326e000 by task kworker/u8:0/12 Workqueue: mtk_vcodec_enc_wq mtk_venc_worker Allocated by task 47: __kasan_kmalloc+0x7f/0x90 fops_vcodec_open+0x85/0x1a0 Freed by task 47: __kasan_slab_free+0x43/0x70 kfree+0xee/0x3a0 fops_vcodec_release+0xb7/0x190 Fix this by calling cancel_work_sync(&ctx->encode_work) before kfree(ctx). This ensures the workqueue handler is both cancelled (if pending) and synchronized (waits for any running handler to complete) before the context is freed. Placement rationale: The fix is placed after v4l2_ctrl_handler_free() and before list_del_init(&ctx->list). At this point, all m2m operations are done (v4l2_m2m_ctx_release() has returned), and we need to ensure the workqueue is synchronized before removing ctx from the list and freeing it. Note: The open error path does NOT need cancel_work_sync() because INIT_WORK() only initializes the work structure - it does not schedule it. Work is only scheduled later during device_run() operations.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.85-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:
    https://security-tracker.debian.org/tracker/linux

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - media: mediatek: vcodec: fix use-after-free in encoder release path The fops_vcodec_release() function     frees the context structure (ctx) without first cancelling any pending or running work in     ctx->encode_work. This creates a race window where the workqueue handler (mtk_venc_worker) may still be     accessing the context memory after it has been freed. Race condition: CPU 0 (release path) CPU 1     (workqueue) --------------------- ------------------ fops_vcodec_release() v4l2_m2m_ctx_release()     v4l2_m2m_cancel_job() // waits for m2m job done mtk_venc_worker() v4l2_m2m_job_finish() // m2m job     done // BUT worker still running! // post-job_finish access: other ctx dereferences // UAF if ctx     already freed // returns (job done) kfree(ctx) // ctx freed Root cause: The v4l2_m2m_ctx_release() only     waits for the m2m job lifecycle (via TRANS_RUNNING flag), not the workqueue lifecycle. After     v4l2_m2m_job_finish() is called, the m2m framework considers the job complete and v4l2_m2m_ctx_release()     returns, but the worker function continues executing and may still access ctx. The work is queued during     encode operations via: queue_work(ctx->dev->encode_workqueue, &ctx->encode_work) The worker function     accesses ctx->m2m_ctx, ctx->dev, and other ctx fields even after calling v4l2_m2m_job_finish(). This     vulnerability was confirmed with KASAN by running an instrumented test module that widens the post-     job_finish race window. KASAN detected: BUG: KASAN: slab-use-after-free in mtk_venc_worker+0x159/0x180     Read of size 4 at addr ffff88800326e000 by task kworker/u8:0/12 Workqueue: mtk_vcodec_enc_wq     mtk_venc_worker Allocated by task 47: __kasan_kmalloc+0x7f/0x90 fops_vcodec_open+0x85/0x1a0 Freed by task     47: __kasan_slab_free+0x43/0x70 kfree+0xee/0x3a0 fops_vcodec_release+0xb7/0x190 Fix this by calling     cancel_work_sync(&ctx->encode_work) before kfree(ctx). This ensures the workqueue handler is both     cancelled (if pending) and synchronized (waits for any running handler to complete) before the context is     freed. Placement rationale: The fix is placed after v4l2_ctrl_handler_free() and before     list_del_init(&ctx->list). At this point, all m2m operations are done (v4l2_m2m_ctx_release() has     returned), and we need to ensure the workqueue is synchronized before removing ctx from the list and     freeing it. Note: The open error path does NOT need cancel_work_sync() because INIT_WORK() only     initializes the work structure - it does not schedule it. Work is only scheduled later during device_run()     operations. (CVE-2026-31584)

Note that Nessus relies on the presence of the package as reported by the vendor.
