Central European Time ofc :-)
I think it stands for Control-flow Enforcement Technology or something
along those lines, but this being Intel it loves to obfuscate stuff and
make it impossible to understand what's being said to increase the
buzzword bong hits.
Its a mostly pointless umbrella term for IBT (Indirect Branch Tracking)
and SHSTK (SHadow STacK), the first of which covers forward edge control
flow and the second covers backward edge control flow.
