Local privilege escalation
Published Aug 13, 2024 · Updated Jul 10, 2025
Improper access control in the Windows Update Stack allows local users with low privileges to elevate privileges on affected Microsoft Windows releases. Microsoft has not published the specific Update Stack component, missing access-control check, or untrusted operation responsible for the elevation. Exploitation requires prior ability to execute low-privileged code on the target; Microsoft does not identify the resulting privilege level.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
