Local privilege escalation to SYSTEM
Published Nov 9, 2022 · Updated Aug 10, 2026
Elevation of privilege in the Microsoft Windows Win32 Kernel Subsystem allows local low-privileged users to gain SYSTEM access. Microsoft has not published the faulty function or the operation it performs on attacker-controlled input. Exploitation requires local code execution under a low-privileged account, needs no user interaction, and grants the operating system's highest privilege level.
