Local privilege escalation via unrestricted driver IOCTLs
Published May 22, 2024 · Updated Feb 13, 2025
Privilege escalation in ASUSTeK Computer Inc. GPU Tweak II 1.4.5.2 allows local users to execute arbitrary code through crafted IOCTL requests. The IOMap64.sys dispatch path exposes physical-memory mapping and I/O-port reads and writes without restricting low-privileged callers of DeviceIoControl. A local low-privileged session is required; successful abuse reaches high-privilege code execution and can disclose memory or crash the host.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
