Why is it that every time there’s drama about hardware, its something I own?
That’s because of monopolies… There are only two brands of PC CPUs you could own…
That’s a duopoly and is also not true, there are ARM processors readily available outside of Intel and AMD.
Nice to know that security researchers are giving AMD some love too. Ill be sure to turn the patch off on my 3600 once it rolls around (can’t be losing any frames for something silly like security)
That’s a very bad idea.
The bad news is that the exploit doesn’t require physical hardware access and can be triggered by loading JavaScript on a malicious website.
How come branch prediction seems so vulnerable to exploits? Both spectre and meltdown were also caused by branch prediction not working quite right.
The more steps in the instruction pipeline the more ways there are for there to be an error where some result doesn’t get erased when undoing stuff from the wrong branch. It’s basically like telling someone to move into a new house and get settled then stopping them six hours in and trying to make sure you get all their stuff out.
affects all Zen 2-based Ryzen, Threadripper, and EPYC CPUs
I know they’re probably pretty common, all my stuff ended up being Zen 3. Here’s hoping they don’t find similar issues in later generations.
I’ve got an older 3900X that’s Zen 2, but I’m otherwise clear, too.
It’s kind of hard to figure out which Zen # a CPU falls under, so here’s the Wiki page listing all Zen 2 CPUs.
Intel had something like this as well (side channel attack?). I remember it because Linus Torvalds (creator of Linux kernel) ripped Intel a new one.
They’ve had a couple. Spectre is the one to which you’re referring, I bet.
Oh poop.
Makes me glad I’m using an ancient CPU from before the vulnerability.
Well
that’s not great
Feeling pretty smudge about my 2400g and RX580 “gaming” rig.
I’m just going to pretend I didn’t buy any AMD surface laptops.
Welp. Thankfully my current AMD desktop PC will be the last one I’ll be using in my whole lifetime – RISC-V 4va. :^)
Click bait. Alleady fixed on every platform
Why are users on Linux stating the opposite then?
Misled by stupid clickbait? I’m on linux, it’s fixed by microcode update in linux-firmware and kernel mitigation, commit says july 24 22:07:56
So it was patched literally 2 days ago.
You think everyone updates their kernel off source that quickly? This vulnerability is absolutely still out in the wild.
“Could take many months to fix” is bullshit
AMD lol
This is not a back-end at all…
