  • The new class of vulnerabilities in Intel processors arises from speculative technologies that anticipate individual computing steps.
  • Openings enable gradual reading of entire privilege memory contents of shared processor (CPU).
  • All Intel processors from the last 6 years are affected, from PCs to servers in data centres.

Thankfully my Thinkpads from the last decade are not affected.

This sounds just like Spectre/heartbleed. Haven't we learned our lesson with speculative computation? I guess not...

Well you know what they say, if it was a bad idea 10 fucking years ago, then let's do it again!

With massive OOO pipelines, what's the alternative?

[–] Bogus007@lemm.ee 5 points 11 hours ago

Intel has not learned, still making money on crap chips.

[–] domi@lemmy.secnd.me 48 points 23 hours ago

Intel has already deployed a fix for this in the 13th and 14th gen by permanently damaging the chip and crashing. Checkmate hackers.

Another day, another speculative execution vulnerability.

No catchy name for the vulnerability? It can’t be that bad, then…

[–] rockSlayer@lemmy.blahaj.zone 43 points 1 day ago (1 children)

Let's call it Son of Spectre

Bond, James Bond. Junior.

This vulnerability fundamentally undermines data security, particularly in the cloud environment where many users share the same hardware resources.

Intel gets punched again.

Who, my good friend, fucking WHO still buys Intel for the servers? It sucks so hard, I don't get it.

[–] Cocodapuf@lemmy.world 1 points 2 hours ago (1 children)

Well personally, I've been having a bear of a time trying to get my Ryzen machine to run correctly. I'm starting to think there just aren't good options

[–] msage@programming.dev 4 points 57 minutes ago

I've had numerous Ryzens, with 0 issues.

Fewer Epics, but no issues either.

What issues are you having?

[–] Krudler@lemmy.world 2 points 8 hours ago

I feel pretty duh here. That's a great point.

[–] naeap@sopuli.xyz 20 points 1 day ago* (last edited 1 day ago)

Anyone having a link to a more technical (detailed) description?
This is quite novice orientated and I'd be very interested on how it actually works. Is there anything already disclosed?

Edit: link at the end to the original research/more detailed explanation:

Finally! I've been waiting to expose my processor
