I only skimmed the full report, but it looks like a way of root-kitting a new Intel processor. As noted, Intel has already patched this problem.

- tptacek 17y agoNope, it's a way of installing a persistent rootkit with full access to the hardware (ie, a rootkit like any modern rootkit on non-TXT Intel hardware) even on systems that use TXT and VT-* to prevent that from happening. It's circumvention of a new Intel security feature, but it's not a new compromise in the integrity of the CPU or chipset itself. Even if they hadn't corrected the problem, you'd still be better off with TXT than without it.
