FWIW: I just ran that on my system with the *old* microcode, and it
reports "NOT VULNERABLE" for all three variants too.

No. I don't have it installed on any of my systems, two of which are

This is a similar thread on Arch Linux:

"Wasn't the 20180108 microcode update retracted because of issues? Maybe we

Only because it isn't the latest kernel you have, so it has never had
the latest microcode added into it - it will still be loading the
previous (working) version.

I eventually noticed that too.
So it means that the problem follows the microcode - nothing to do with the
kernel version.

Bug #1760095 (mine) reports it for two 17.10 systems (Intel graphics only) both
on 4.13.0-37-generic.
An 18.04beta system 4.15.0-13-generic with the "same" microcode version is OK.
