MDS: The Newest Speculative Execution Side-Channel Vulnerability

[xorbe]

To be fair, this sounds like a simple fix (clear the damn buffers!) that shouldn't cost much if anything in performance.

Sometimes these secondary functions are on slow serial buses within the chip (saves wiring and flops).

Oh no, they gave it a name, and custom logo, and dedicated website.

Intel, processors designed by monkeys.

If nothing, at least you can get unsafe performance

does it affect AMD?

Same as for meltdown and l1tf

I guess it's time for the another vulnerability that will slow down Intel chips even more. I'll have to enjoy my chips while they're still fast. With how things are looking, maybe the best bet is to go back to early chips that weren't cutting corners (even older than 486) to improve performance and try to make them bearable by putting in SIMD instructions and a huge cache, or maybe abandon x86 for everything besides (offline) video games, where it seems to do well enough.

How long will it take for OpenBSD to refuse to boot on Intel chips because of how insecure they are?

The sad thing is that mentioned hardware mitigations make new chips more vulnerable to the fallout bug.

The zombieload paper didn't visibly mention AMD, but I guess they tried at some intel boxes first. Hopefully someone will test on other CPUs/APUs, too.
