Local API interruption via multiple port binds
Published Feb 6, 2026 · Updated Feb 6, 2026
Denial of service in the Tanium Client API allows local users with system access to interrupt the endpoint service on that system. Tanium maps the issue to multiple binds on the same port but has not disclosed the affected code path or the specific socket operation. Exploitation requires local low-privileged access, and the reported consequence is limited to Client API availability.
