CVE-2024-33219Public exploit

Local privilege escalation via unrestricted IOCTLs

Published May 22, 2024 · Updated Feb 13, 2025

Privilege escalation in ASUS SABERTOOTH X99 Driver 1.0.1.0 allows local users to execute arbitrary code through crafted IOCTL requests. The AsIO64.sys DeviceIoControl dispatch path exposes physical-memory mapping, I/O-port access, and model-specific-register operations without restricting caller privileges. A low-privileged local account can use these kernel-level primitives to gain elevated code execution and disclose or modify protected system data.
