CVE-2025-53807

Local privilege escalation via graphics use-after-free

Published Sep 9, 2025 · Updated Sep 9, 2025

Race condition in Microsoft Graphics Component on affected Windows releases allows local users to elevate privileges through concurrent access. The component accesses a shared resource without proper synchronization, creating a use-after-free when concurrent execution releases an object still in use. Low-privileged local access and winning a high-complexity race are required; successful exploitation grants elevated privileges without user interaction.
