CVE-2026-72484: staging: most: video: avoid double free on video register failure

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.22% (FIRST EPSS).
  • Fixed version: Linux Linux 009d58b73500d0b49f6ae3833f8afcb0ebd9ddbb, 43078449ad6236d839e4d707954d2e36b10a6706, 430ad4ea06a0767fb44a08e2212ceb3a996607ee.

Low priority for now. Upgrade to Linux Linux 009d58b73500d0b49f6ae3833f8afcb0ebd9ddbb, 43078449ad6236d839e4d707954d2e36b10a6706, 430ad4ea06a0767fb44a08e2212ceb3a996607ee or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
