Privilege escalation via push notification race
Published Aug 11, 2026 · Updated Aug 25, 2026
Race condition in Windows Push Notifications in Microsoft Windows allows local authenticated attackers to gain elevated privileges. Microsoft has disclosed only that a shared Push Notifications resource is accessed without proper synchronization, and the CVE record also maps the flaw to CWE-416 without naming the specific object or code path. Exploitation requires local low privileges and winning the timing window, making it a post-compromise escalation issue rather than a remote entry point.
