Frequently Asked Questions
Who can exploit this vulnerability?
An attacker must already be authorized on the affected Windows system and be able to execute code locally. The issue is not described as remotely exploitable.
What is the likely impact of successful exploitation?
Successful exploitation allows local elevation of privilege. The provided severity vector indicates high impacts to confidentiality, integrity, and availability.
Which systems should be assessed?
Assess Microsoft Windows 11, Microsoft Windows Server 2025, and other Microsoft Windows systems identified in your environment as using VBS Enclave functionality. The supplied data does not identify affected build numbers or whether VBS Enclave is enabled by default.
What should be prioritized if remediation cannot be applied immediately?
Prioritize limiting untrusted local access and reviewing accounts with local authorization, since exploitation requires an authorized local attacker. Monitor for suspicious privilege escalation activity on affected Windows systems.
