SYSTEM privilege escalation via Win32k use-after-free
Published May 14, 2024 · Updated May 3, 2025
Use-after-free in Win32k in Microsoft Windows allows local users to elevate privileges to SYSTEM by running a crafted application. Win32k accesses memory after releasing it, but Microsoft has not disclosed the affected object, function, or attacker-controlled trigger. Exploitation requires prior low-privilege local access; successful exploitation grants SYSTEM-level control of the affected host.
