Frequently Asked Questions
Who can exploit this vulnerability?
An attacker must already be authorized on the affected system and able to execute code locally. The available data does not indicate that remote or unauthenticated exploitation is possible.
Which systems should be assessed?
Assess Microsoft Windows 10, Windows 11, Windows Server 2019, Windows Server 2022, and Windows Server 2025 systems, particularly where untrusted or lower-privileged users can obtain local access.
What level of access could exploitation provide?
Successful exploitation can elevate a locally authorized attacker's privileges. The reported impact includes high confidentiality, integrity, and availability effects.
Is exploitation straightforward?
The supplied vector rates attack complexity as high. Exploitation involves a race condition and use-after-free condition in the Windows Connected Devices Platform Service.
