Privilege escalation via improperly locked sensitive memory
Published Jul 8, 2025 · Updated Feb 13, 2026
Privilege escalation in Microsoft Windows UPnP Device Host allows remote authenticated users to gain elevated privileges over an adjacent network. The component stores sensitive data in memory that is not properly locked, but Microsoft has not disclosed the affected code locus or how adjacent input reaches that memory. Exploitation requires low privileges, adjacent-network access, no user interaction, and high-complexity conditions; success can compromise data and system operation.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
