Any news? We are now the 05/13/2017.
What about the DH87RL? It is not mentioned in your list but it seems also affected.
No announcement of availability as yet.
DH87RL is NOT affected; it has only consumer firmware running on its Management Engine. Only boards that have Q and B chipsets can possibly run the VPro firmware and thus be susceptible to the AMT vulnerability. The list of susceptible boards provided above is accurate.
Epected availability dates for the BIOS versions that will fix this issue will be tracked at Intel® Active Management Technology Escalation of Privilege Advisory... Please refer to that page for further updates.
