Frequently Asked Questions
Who can exploit this vulnerability?
An attacker must already be authorized on the affected Windows system and have local access. The issue is an elevation-of-privilege vulnerability, so it can allow a lower-privileged local user to gain higher privileges.
Which systems should be assessed?
Assess Microsoft Windows 10, Windows 11, Windows Server 2016, Windows Server 2019, Windows Server 2022, and Windows Server 2025 systems. The provided information does not identify unaffected versions, configuration prerequisites, or a workaround.
How can I determine whether a system is exposed?
Identify whether the system runs one of the listed Windows products and has local authorized users who could execute code. The available information does not provide detection indicators, affected build numbers, or exploitation telemetry.
