Local service interruption through undisclosed mechanism
Published May 11, 2021 · Updated Aug 3, 2024
Denial of service in Windows Desktop Bridge on Windows 10 and Windows Server versions 2004 and 20H2 allows local users to interrupt service. Microsoft has not published the affected function or the operation that mishandles attacker-controlled input, so the concrete failure mechanism remains undisclosed. Exploitation requires local low-privilege access and no user interaction; the documented consequence is availability loss without data disclosure or modification.
