CVE-2026-72484

Kernel crash via failed video device registration

Published Aug 15, 2026 · Updated Aug 15, 2026

Double free in the Linux kernel staging MOST video driver allows local users to crash the system during failed device registration. When device_register() fails, its release callback frees mdev->vdev before comp_register_videodev() releases the same object again. Exploitation requires local access and a registration failure in the MOST video path; the established consequence is a kernel crash.
