Frequently Asked Questions
Who can exploit this vulnerability?
An attacker must already be authorized on the affected Windows system and able to execute code locally. The provided vector indicates high privileges are required.
Is this remotely exploitable over the network?
The supplied attack vector is local, so the available information describes local code execution rather than direct network-based exploitation.
Which systems should be assessed?
Assess Microsoft Windows 10, Windows 11, and the listed Windows Server releases: 2012, 2012 R2, 2016, 2019, 2022, and 2025.
What is the potential impact if exploitation succeeds?
Successful exploitation can allow code execution and is rated as having high confidentiality, integrity, and availability impact in the supplied vector.
