Intel® Converged Security and Management Engine Version Detection Tool Version: 126.96.36.199 reports the NUC6CAYH as being vulnerable on the Trusted Execution Engine being at version 188.8.131.520
I believe there already is a TXE update, eg: 184.108.40.2068
Please update ASAP
The BIOS team indicated that the fix for this is included in BIOS AY0069, which is in the validation pipeline. They don't commit to delivery dates, so you will need to watch for this build appearing.
