Frequently Asked Questions

Who can exploit this issue?

An attacker needs kernel-level privileges to supply an arbitrary memory address through an I/O command. This is therefore most relevant after an attacker or malicious local component has already obtained kernel-level access.

What impact can exploitation have?

Successful exploitation can tamper with subsequent system information or cause the system to crash.

How can I determine whether my system is affected?

Check whether the system uses an ASUS motherboard and consult the “Security Update for Multiple ASUS Motherboards” section of the ASUS Security Advisory for affected firmware information.
