CVE-2026-69319

CVE-2026-69319 is a race condition involving improper synchronization of a shared resource (CWE-362, with an associated use-after-free risk per CWE-416) in the Windows USB Video Driver. It is triggered when concurrent operations race on a shared driver resource, and can be exploited by an authorized local attacker who is already able to run low-privileged code on the target machine. Successful exploitation elevates the attacker's privileges locally, with high impact on confidentiality, integrity, and availability (CVSS 3.1: 7.0, AV:L/AC:H/PR:L/UI:N). Any Windows system running the affected USB Video Driver component is exposed in principle, though high attack complexity and the local-access requirement reduce practical risk. No exploitation is known: there is no public proof-of-concept, it is not listed in CISA KEV, and EPSS assigns only a 0.2% probability of exploitation within 30 days (9th percentile).

What to do: Apply Microsoft's security update for the Windows USB Video Driver via Windows Update as soon as the fix ships, since no fixed version or KB number is provided in the source data. Prioritize multi-user hosts such as RDS/session servers, kiosks, and shared workstations where low-privileged local code execution is more likely, and verify the updated driver after patching. Given the high attack complexity, local-only vector, and absence of known exploitation, routine patch-cycle prioritization is reasonable; no workarounds or public exploit exist.
