Local privilege escalation via kernel race condition
Published Nov 11, 2025 · Updated Feb 26, 2026
A race condition in the DirectX Graphics Kernel in affected Windows releases allows local users to elevate privileges. Microsoft identifies unsynchronized concurrent access to a shared kernel resource but has not disclosed the specific object or code path involved. A low-privileged local account and successful race timing are required; exploitation grants higher privileges on the same system.
