Summary

An attacker with permission to send push notifications to a Windows system may be able to gain elevated privileges on the system, potentially allowing them to access sensitive data or make unauthorized changes. This vulnerability exists because Windows Push Notifications does not properly synchronize access to shared resources, allowing an attacker to take advantage of a 'race condition'. To protect your system, ensure that Windows is updated with the latest security patches and consider implementing additional security measures to restrict access to push notification services.
