Name of the Vulnerable Software and Affected Versions: ASUS GPUTweak II versions prior to 2.3.0.3

Description: The issue allows low-privileged users to trigger a stack-based buffer overflow in AsIO2 64.sys and AsIO2 32.sys. This could enable low-privileged users to achieve Denial of Service via a DeviceIoControl.

Recommendations: For versions prior to 2.3.0.3, update to version 2.3.0.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the AsIO2 64.sys and AsIO2 32.sys drivers to minimize the risk of exploitation.
