He got the affected version numbers exactly right, but according to Intel he got the affected hardware wrong (consumer hardware unaffected).
That tells me he got the information from an unmentioned source. If he had the details himself he would be able to confirm what hardware it is present on by testing it.
The explanation for that error code be that the source have been vague about it or not tested it on a lot of hardware, or isn't even a firsthand source, or that the journalist misunderstood it.
Ah. To be fair, that intel.com link is confusing, because it sends you off to see if you have "Intel® vPro", which is certainly on consumer hardware, like various i5 and i7 systems. Which does not jive with the earlier line "This vulnerability does not exist on Intel-based consumer PCs". It sort of depends on your definition of consumer hardware.
Overall, though, it does seem to validate the sequence was something like "he had a suspicion" then "intel released an update".
