Frequently Asked Questions
Who is exposed to exploitation?
Systems running the affected Microsoft Windows 11 or Microsoft Windows Server 2025 software are in scope. Exploitation is local, so an attacker must already be able to execute as an authorized user on the target.
What level of access does an attacker need?
The attacker requires high privileges before exploitation, as indicated by PR:H. No user interaction is required.
What could successful exploitation allow?
Successful exploitation can elevate an authorized local attacker's privileges. The supplied vector indicates high impacts to confidentiality, integrity, and availability.
Is this remotely exploitable?
No. The attack vector is local (AV:L), so the vulnerability is not directly exploitable over the network based on the provided information.
