Effecting 5th generation in newer Intel chips including Xeon and Atom as well Core-i series. In a nutshell, it allows undetectable by OS access to the machine. So, you can get in and manipulate the machine and have direct access to memory all below the OS and totally invisible to the user.

The sad reality is even if patched by Intel it will require all OEM companies to mush BIOS updates. And then those updates need to be pushed to clients by system admins. Basically, this flaw will never get fixed for the most part in the real world. Leaving millions of exposed systems.
