CVE-2026-32075 is an elevation-of-privilege vulnerability in Windows Universal Plug and Play (UPnP) Device Host caused by a use-after-free condition. The flaw arises when the component accesses memory after it has been freed, creating a memory safety error that can be leveraged by a locally authenticated attacker under specific conditions. Microsoft classifies the issue as Important and indicates that exploitation requires local access, low privileges, and no user interaction. Successful exploitation can result in privilege escalation from a low-privileged context to administrator on the affected system.
