Detailsinfo

A vulnerability was found in Linux Kernel up to 6.1.188/6.6.157/6.12.110/6.18.52 and classified as very critical. Affected by this issue is the function video_unregister_device of the component video-i2c. The manipulation with an unknown input leads to a denial of service vulnerability. Using CWE to declare the problem leads to CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. Impacted is confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: media: video-i2c: use vb2_video_unregister_device on driver removal The driver uses vb2_fop_release() as its file release operation, so vb2_video_unregister_device() should be used instead of video_unregister_device() during driver removal. This ensures that the vb2 queue is properly disconnected before the video device is unregistered.

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2026-98915 since 09/25/2026. The exploitation is known to be easy. Local access is required to approach this attack.
