Privilege escalation via untrusted IOCTL pointer write
Published Aug 11, 2026 · Updated Aug 11, 2026
Untrusted pointer dereference in ASUS GPU Tweak III, GPU Tweak II, AI Suite 3, and VGAdll allows local users to escalate privileges. An affected IOCTL handler treats an attacker-supplied address as the destination for a specific-value write, allowing memory at an arbitrary address to be overwritten. Exploitation requires high-privileged local access; affected versions are 2.1.1.7, 2.4.0.0, 2.1.2.0, and 0.0.7.8 and earlier, respectively.

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.
