Frequently Asked Questions
Who is exposed to this vulnerability?
Systems running Microsoft Windows 11 or Microsoft Windows Server 2025 are identified as affected. Exploitation is local, so exposure depends on whether an attacker can already authenticate to or otherwise execute code on the system.
What does an attacker need to exploit it?
The attacker must be authorized and have local access. No user interaction is required, and successful exploitation can result in elevated privileges with high impact to confidentiality, integrity, and availability.
