CVE-2024-55408

Local privilege escalation via unrestricted driver IOCTLs

Published Jan 6, 2025 · Updated Feb 11, 2025

Missing authorization in AsusSAIO.sys for ASUS System Control Interface V1 before 1.0.30.0 and V3 before 3.1.41.0 allows local privilege escalation. The driver dispatches crafted DeviceIoControl requests without checking caller privileges, exposing physical-memory mapping, I/O-port access, and model-specific register reads and writes. Low-privileged local access is sufficient to execute code with elevated privileges or disclose protected information.
