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:
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?
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?
