Local privilege escalation via use-after-free
Published Aug 12, 2025 · Updated Feb 13, 2026
Use-after-free in Microsoft Windows Connected Devices Platform Service allows local users with low privileges to elevate privileges. The service reuses or references freed memory, but Microsoft has not disclosed the affected function, object lifetime error, or triggering input. Exploitation requires local low-privileged access and high-complexity conditions; success raises the user's privileges on the affected host.
