Privilege escalation via ALPC port object race
Published Sep 13, 2022 · Updated Mar 11, 2025
A race condition in Microsoft Windows ALPC allows local users with low privileges to execute code with elevated privileges. The ALPC port object handles concurrent creation operations without adequate synchronization, producing a use-after-free condition. Exploitation requires local low-privileged access and winning the race; success grants control at higher privileges.
