Local privilege escalation
Published Aug 12, 2021 · Updated Aug 10, 2026
Elevation of privilege in Microsoft's Windows Digital TV Tuner device registration application allows local users to gain elevated rights. Microsoft has not published the faulty function, input path, or privilege-management operation within the registration application. Exploitation requires existing low-privilege local access and no user interaction; successful use raises the attacker's rights on the host.
