SYSTEM privilege escalation via use-after-free
Published May 14, 2024 · Updated May 3, 2025
Use-after-free in Microsoft Windows DWM Core Library allows local users with low privileges to gain SYSTEM privileges on affected builds. Microsoft identifies the weakness class but does not disclose the object, function, or lifetime sequence that reuses freed memory. Exploitation requires local low-privileged access and no user interaction; success grants SYSTEM-level control of the host.
