      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: mc, v4l2: serialize REINIT and REQBUFS with req_queue_mutex\n\nMEDIA_REQUEST_IOC_REINIT can run concurrently with VIDIOC_REQBUFS(0)\nqueue teardown paths. This can race request object cleanup against vb2\nqueue cancellation and lead to use-after-free reports.\n\nWe already serialize request queueing against STREAMON/OFF with\nreq_queue_mutex. Extend that serialization to REQBUFS, and also take\nthe same mutex in media_request_ioctl_reinit() so REINIT is in the\nsame exclusion domain.\n\nThis keeps request cleanup and queue cancellation from running in\nparallel for request-capable devices.",
