CVE-2024-33222

Kernel code execution via unrestricted physical-memory IOCTLs

Published May 22, 2024 · Updated Mar 13, 2025

Privilege escalation in ASUS ATSZIO Driver 0.2.1.7 allows local users to execute arbitrary code through crafted IOCTL requests. ATSZIO64.sys exposes physical-memory mapping, I/O-port access, and model-specific-register operations through DeviceIoControl without restricting low-privileged callers. Any local low-privileged process can invoke these kernel capabilities to read or modify hardware-backed state and run code with elevated privileges.
