SYSTEM privilege escalation through undisclosed Win32k flaw
Published Apr 15, 2022 · Updated Jan 2, 2025
Elevation of privilege in Microsoft Windows Win32k allows local users with low privileges to gain SYSTEM-level permissions. Microsoft has not published the affected Win32k code path or the unsafe operation that enables the elevation. Exploitation requires prior local code execution under a low-privileged account; successful exploitation grants the highest Windows privilege level.
