CVE-2026-68825

Local privilege escalation via driver use-after-free

Published Sep 8, 2026 · Updated Sep 9, 2026

Use-after-free in the Windows Bind Filter Driver allows local users on affected Windows builds to elevate privileges through local execution. The driver accesses an object after its memory has been freed, but Microsoft has not disclosed the affected function, object type, or triggering input. A low-privileged account and local execution are required; successful exploitation grants elevated privileges on the host.
