Local privilege escalation via ALPC race
Published Mar 9, 2022 · Updated Jul 8, 2025
Elevation of privilege in Microsoft Windows ALPC allows local users on affected builds to gain elevated execution through a race condition. Microsoft identifies ALPC and improper synchronization but has not published the affected function, shared resource, or incorrect operation. Successful exploitation requires existing low-privilege local access and winning a high-complexity race; it grants elevated code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
