Intel released a disclosure today on a series of vulnerabilities in their management engine and trusted execution engine, affecting Surface Studio (and presumably other Surface devices).

They included a tool to check to see if your system is vulnerable:

I've run the tool on a Surface Studio and confirmed that is vulnerable and requires Microsoft to issue a firmware update with the patch Intel provided. As they have presumably already given the patch to you, I'm wondering how long you're going to leave us all vulnerable to this before you release the required firmware update to patch this?

We need this fixed ASAP!
