No, it is misleading. An exploit with no remediation is not remotely comparable to a normal root exploit, which can be fixed with a simple OS reinstall.
Edit: And their follow-up comment, “if somebody has ring 0 access that shouldn’t, you already have problems,” is dangerously misleading. While technically true that you would have a problem in both scenarios, presenting it that way is like telling someone not to worry about losing a leg because their sprained ankle is already a problem.
It’s always been a thing that the only way to completely be safe after malware is yeeting the old system and getting a new one…
And even then there have been actively exploited issues where the system gets re-infected when reloading the data from a backup. (My memory is a bit rusty on that one, but it was just data being restored, nothing that should install anything)
They’re intrinsically linked, in fact. If you have kernel access, you can do any number of things, including but not limited to persistent rootkits. I agree that this bug is one step further, since it affects the processor itself, but if somebody has ring 0 access that shouldn’t, you already have problems.
One of these things is not like the other.
Read it again, in context. What they said is perfectly valid.

Yeah, turning an exploit into one that survives a fresh install is a big deal.
