Vulnerability identifier: #VU142664

CSH Severity: Low

CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-74437

CWE-ID: CWE-362

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to improper synchronization in uvc_status_stop in the uvcvideo driver when handling asynchronous control status events. A local user can trigger a deadlock condition to cause a denial of service.

Exploitation requires a UVC camera with an asynchronous control.
