CVE-2022-38021

Local privilege escalation via undisclosed race condition

Published Oct 11, 2022 · Updated Jan 2, 2025

Race condition in Microsoft Windows Connected User Experiences and Telemetry allows local users to gain elevated privileges. Microsoft has not published the shared resource, unsynchronized operation, or concrete race sequence within the component. Exploitation requires existing low-privilege local execution and winning a high-complexity timing race; the bounded result is elevated execution.
