Frequently Asked Questions
Who is exposed to this issue?
Systems running the listed Windows 10, Windows 11, or Windows Server releases are in scope. Exploitation is local, so the attacker must already be able to execute on the affected system.
What access and conditions does an attacker need?
An attacker needs low-privileged authorization on the target and must interact with the system locally. Successful exploitation also requires user interaction and winning a race condition involving a shared resource.
What is the potential impact if exploitation succeeds?
A successful attacker can elevate privileges. The supplied vector rates confidentiality, integrity, and availability impacts as high.
