Local privilege escalation via stale memory access
Published Sep 8, 2026 · Updated Sep 9, 2026
Use after free in Microsoft Windows Connected User Experiences and Telemetry allows local users with low privileges to elevate privileges. Microsoft identifies stale-memory use in the component but has not disclosed the affected function, object lifetime, or triggering input. Exploitation requires local code execution, low privileges, no user interaction, and a high-complexity condition; success grants elevated control over the host.
