CVE-2022-26928

SYSTEM privilege escalation via race condition

Published Sep 13, 2022 · Updated Mar 11, 2025

A race condition in the Windows Photo Import API allows local users with low privileges to gain SYSTEM privileges on affected Windows builds. Microsoft identifies a timing race in the API but has not published the shared resource, function, or sequence that lacks synchronization. Exploitation requires an existing local foothold and winning the race; success grants complete SYSTEM-level control.
