A free and unofficial patch is now available for a zero-day local privilege escalation vulnerability in the Windows User Profile Service that lets attackers gain SYSTEM privileges under certain conditions.
The bad news is that it impacts fully-updated devices running all Windows versions, including Windows 10, Windows 11, and Windows Server 2022.
While Microsoft is still working on a security update to address this zero-day flaw, the 0patch micropatching service has released Thursday a free unofficial patch.
Windows 10 v21H1 updated with October or November 2021 Updates.
Windows 10 v20H2 updated with October or November 2021 Updates.
Windows 10 v1909 updated with October or November 2021 Updates.
