Deserialization of untrusted data in Intel Thunderbolt DCH drivers for Windows before version 88 allows local users to interrupt service. Intel has not disclosed the affected driver component, serialized data format, or operation that processes the untrusted data. Successful exploitation requires authenticated local access and affects availability only; Intel describes the result as denial of service.
