SYSTEM privilege escalation via use-after-free race
Published Dec 9, 2025 · Updated Apr 16, 2026
Use after free in Windows DirectX allows local users on affected Windows releases to elevate privileges through a race condition. A race in the DirectX graphics kernel permits access to an object after its memory has been released, creating an exploitable lifetime error. Successful exploitation requires low-privileged local access and winning the race, after which the attacker gains SYSTEM privileges.
