Frequently Asked Questions
Who is exposed to this vulnerability?
Systems running the listed Microsoft Windows client or server products with the Windows PCI Bus Driver are in scope. Exploitation is local, so it does not directly expose systems to a remote unauthenticated attacker.
What access does an attacker need to exploit it?
An attacker must already be authorized on the affected system and able to execute code locally with low privileges. No user interaction is required according to the supplied vector.
What is the likely impact if exploitation succeeds?
Successful exploitation can elevate the attacker's privileges and may result in high impacts to confidentiality, integrity, and availability. The vector also indicates a scope change.
