Name of the Vulnerable Software and Affected Versions AIDA64 versions prior to 5.99

Description An issue was discovered in kerneld.sys. The vulnerable driver exposes a wrmsr instruction via IOCTL 0x80112084 and does not properly filter the Model Specific Register (MSR). Allowing arbitrary MSR writes can lead to Ring-0 code execution and escalation of privileges.

Recommendations For versions prior to 5.99, update to version 5.99 or later to resolve the issue. As a temporary workaround, consider restricting access to the kerneld.sys driver to minimize the risk of exploitation. Avoid using the IOCTL 0x80112084 instruction in the affected driver until the issue is resolved.
