Privilege escalation via improperly locked sensitive memory
Published Apr 8, 2025 · Updated Aug 10, 2026
Improper memory locking in Microsoft Windows UPnP Device Host allows remote authenticated users to elevate privileges over a network. The component stores sensitive data in memory that is not correctly locked, but Microsoft has not disclosed the specific object, function, or network trigger involved. Successful exploitation grants higher privileges on the affected host and requires existing low-level credentials plus high-complexity conditions.
