Wow dude. Next time I'll make sure to put it in the thread title knowing that some people goes straight from not reading the article to not even read the opening post.

It says it can but will be harder to obtain. No choice but to disable it.

Sure, but that doesn't equate to "problem solved". Problem mitigated perhaps, but not solved.

Ok, temporary solution. A more permanent one is to not turn on the PC.

Furthermore, Intel released 18 security related advisories yesterday (the 12th), as well as a number of mitigating patches (which don't necessarily fix all the holes). Anyway, Linux users have already started seeing the patches, but as of now there's no word yet on when they'll start showing up elsewhere.

ZDnet's got an easy to follow article on the topic, if you're interested in it:

Intel's Cascade Lake CPUs impacted by new Zombieload v2 attack

Sidenote: gamers will love this: The Gaming Performance Impact From The Intel JCC Erratum Microcode Update. Though the article is geared toward Linux gamers, expectations are that Windows gamers will also take a hit in framerates.
Damn that's bad

Glad I stayed with the bios revision before security patches were a thing.

I know this is bad for shared public servers, but have any home users been infected or exploited by any Spectre malware yet? Is the net effect of these mitigations nothing more than performance mitigation on older CPUs?

so i assume this will get added to my inspectre tool for disabling all this perf. killing nonsense that doesn't affect my in-home gaming computer in the slightest?

R.I.P. Zawarudo, may you OC angels' wings in heaven.
If something appears too good to be true, it probably is.

lol, I bought a 9900KS to replace my P0 9900k to get the hardware mitigations for MDS inherent to the R0 stepping. Now, the day before it's delivered, they announce that an exploit that affects R0, which Intel has known about before they disclosed MDS.

Before I return it, what is the performance impact of disabling TSX?
