Improper access control in Intel Thunderbolt DCH Drivers for Windows before 88 allows local users to escalate privileges via local access. Intel identifies the weakness only as improper access control and has not published the affected driver component or incorrect authorization operation. A low-privilege authenticated Windows session is required; successful exploitation grants elevated privileges across a security boundary.
