CVE-2022-41975

Local privilege escalation via MSI Repair mode

Published Sep 30, 2022 · Updated May 20, 2025

Local privilege escalation in RealVNC VNC Server before 6.11.0 and VNC Viewer before 6.22.826 on Windows allows local users to gain elevated privileges. The Windows MSI packages mishandle privileged Repair-mode operations, but RealVNC has not disclosed the affected installer action or attacker-controlled resource. Exploitation requires local low-privileged access and MSI Repair under unspecified circumstances; the resulting privilege level is undisclosed.
