Local privilege escalation through undisclosed launcher flaw
Published Jan 11, 2022 · Updated Jan 2, 2025
Elevation of privilege in Windows System Launcher in affected Windows releases allows local users to gain elevated privileges. Microsoft has not published the vulnerable function or the operation that mishandles attacker-controlled input. Exploitation requires existing low-privilege local access and a high-complexity condition; successful attacks compromise confidentiality, integrity, and availability.
