Frequently Asked Questions
Who can exploit this vulnerability?
An attacker must already be authorized to access a vulnerable Windows system and exploit the issue locally. The provided data does not indicate that it can be exploited remotely or without prior access.
Which systems are listed as affected?
The affected software list includes Microsoft Windows 10, Windows 11, Windows Server 2016, Windows Server 2019, Windows Server 2022, and Windows Server 2025.
What level of access does an attacker need before exploitation?
The vulnerability requires low privileges (PR:L) and no user interaction (UI:N). Successful exploitation can elevate the attacker’s privileges locally.
What is the potential impact of successful exploitation?
The supplied vector rates confidentiality, integrity, and availability impacts as high. An attacker who successfully elevates privileges could therefore have high impact across all three security properties.
