Why is it that every time there’s drama about hardware, its something I own?
Planned fix
December 2023
Yikes.
How come branch prediction seems so vulnerable to exploits? Both spectre and meltdown were also caused by branch prediction not working quite right.
It wasn’t branch prediction alone, it was the cache combined with branch prediction. The problem is that even discarded outcomes fill the cache with data. Those older vulnerabilities also had the problem that the access permissions check was done after the branch prediction. It’s probably too expensive to do when it’s not even clear yet whether the branch is going to be taken (that’s just speculation on my part though).
(that’s just speculation on my part though).
I see what you did there, even if you didn’t :)
I’m just going to pretend I didn’t buy any AMD surface laptops.
Well
that’s not great
Makes me glad I’m using an ancient CPU from before the vulnerability.
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
