Massive CPU Security Flaws Revealed


#462

Yeah, another intel bug like Meltdown. AMD is definitely looking better.


#463

Name your new notable thing “SPOILER” to make it virtually search engine kryptonite, gg.


#464

So, this sounds really, really bad, especially to cloud providers. That’s a monstrous number of CPUs that have to be replaced.


#465

For those who aren’t afraid of the flaws, it may mean a lot of cheap used hardware appearing on the market soon. I mean, you would think?


#466

Are we reasonably certain that the only reason similar flaws haven’t been found in AMD is because of security by obscurity? I don’t have any reason to think they are vulnerable, but then again, is anyone actually working on attacking them, given how prevalent Intel is?


#467

Don’t know, but that approach has worked pretty damned well for macs for the last two decades.


#468

That’s one possible explanation, another is that AMD just didn’t have the same level of optimizations that Intel had, and hence has fewer surfaces to attack.


#469

According to https://www.theregister.co.uk/2019/03/05/spoiler_intel_processor_flaw/

The researchers also examined Arm and AMD processor cores, but found they did not exhibit similar behavior.


#470

For this specific bug, yes. That wasn’t the point.
