Local privilege escalation via use-after-free race
Published Mar 10, 2026 · Updated Mar 10, 2026
Race condition in Windows Device Association Service across affected Windows releases allows local users to elevate privileges. The service accesses a shared resource concurrently without proper synchronization, producing a use-after-free condition; Microsoft has not disclosed the affected function or object lifecycle. Exploitation requires low-privilege local access and successful race timing, and yields elevated execution in the service's security context.
