  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: most: video: avoid double free on video register failure\n\ncomp_register_videodev() allocates a video_device with\nvideo_device_alloc() and releases it if video_register_device() fails.\n\nThis can double free the video_device when __video_register_device()\nreaches device_register() and that call fails:\n\n  video_register_device()\n    -> __video_register_device()\n       -> device_register() fails\n          -> put_device(&vdev->dev)\n             -> v4l2_device_release()\n                -> vdev->release(vdev)\n                   -> video_device_release(vdev)\n\n  comp_register_videodev()\n    -> video_device_release(mdev->vdev)\n\nUse video_device_release_empty() while registering the device so that\nregistration failure paths do not free mdev->vdev through vdev->release().\ncomp_register_videodev() then releases mdev->vdev exactly once on failure.\nRestore video_device_release() after successful registration so the\nregistered device keeps its normal lifetime handling.\n\nThis issue was found by a static analysis tool I am developing.",
