Frequently Asked Questions
1
Who is realistically exposed to exploitation?
Exploitation requires an attacker who already has high privileges on a system using the AMD Kernel Mode Driver. The attack also requires user interaction and has high attack complexity, so it is not a straightforward remote attack against an unprivileged user.
2
What could a successful exploit achieve?
A privileged attacker could create a double-free condition through release of an invalid pointer in the driver. This could potentially lead to arbitrary code execution with impacts to confidentiality, integrity, and availability.
