fkie_cve-2026-72484

In the Linux kernel, the following vulnerability has been resolved:

staging: most: video: avoid double free on video register failure

comp_register_videodev() allocates a video_device with video_device_alloc() and releases it if video_register_device() fails.

This can double free the video_device when __video_register_device() reaches device_register() and that call fails:

video_register_device() -> __video_register_device() -> device_register() fails -> put_device(&vdev->dev) -> v4l2_device_release() -> vdev->release(vdev) -> video_device_release(vdev)

comp_register_videodev() -> video_device_release(mdev->vdev)

Use video_device_release_empty() while registering the device so that registration failure paths do not free mdev->vdev through vdev->release(). comp_register_videodev() then releases mdev->vdev exactly once on failure. Restore video_device_release() after successful registration so the registered device keeps its normal lifetime handling.

This issue was found by a static analysis tool I am developing.
