Local tampering via unauthenticated critical function
Published Sep 8, 2026 · Updated Sep 10, 2026
Missing authentication in Windows Power Dependency Coordinator allows local users to tamper with protected system state. Microsoft has not disclosed the critical function, callable interface, or exact state modified when the component omits the required authentication check. Exploitation requires local low-privilege access, needs no user interaction, and produces integrity impact without reported disclosure or service interruption.
