CVE-2026-72484
Estado: RecibidaSin puntuar—
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:
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.
