Local privilege escalation via incorrect resource permissions
Published Jan 17, 2025 · Updated Jun 9, 2026
Local privilege escalation in affected Microsoft Windows releases allows local users to gain elevated privileges through Secure Kernel Mode. Microsoft identifies incorrect permission assignment for a critical Secure Kernel Mode resource but has not disclosed the resource or faulty operation. Exploitation requires low-privileged local access and no user interaction; the public record does not identify the resulting privilege level.
