it's the fault of Intel, why don't they recall all the CPU? just like vehicle company

Doesn't this affect all of their CPUs going a long way back? And how do you recall embedded or laptop CPUs, which are often soldered in-place? A recall would be great, but there's no way they'd be able to do it. Vehicle recalls are a bit different because they impact physical safety. Digital safety doesn't get the same priority.

I don't think they would be able to produce all necessary CPUs. Replacing all current stock would create a huge problem. Replacing all sold cpus from the last two years would be a huge problem, even if (and I don't know how complicated or not it is) it would be quite simple to redesign all these chips, how long would it take to do that?

Then imagine all chips from 1995 to 2015, having to make them again, they don't have the machines anymore.

Earlier quoted context omitted.

How about they go into bankruptcy with most of the world’s computer users as their creditors? Maybe not, but it’s terrifying that you can avoid responsibility by fucking up on a larger scale than most.

I'm sure Intel has a liability insurance policy that covers this type of thing.

Maybe, but that assumes they get the payout, that they did everything on their end of that deal, etc. Insurers don’t like to pay.

Would this entire Meltdown/Spectre thing count as the biggest mess-up of computing history? When yesterday the PoC repo was posted here, the spy.mp4 demo video gave me some chills. And now I can't update my OS before making an installation USB because Canonical can't just follow Linus' releases. Thanks.

Link to the demo?

Also vehicle recalls are usually done by fixing stuff next time the vehicle comes in for regularly scheduled service. How often does your computer get those?

Depends on the recall, the GM ignition recall was done on an independent appt basis. (besides you should not be taking your car to the dealer if you value your wallet)

You need a new dealer...most have greatly improved customer service experiences these days, and many independents are no panaceas...

It must be up there amongst the greats, probably with the "halt and catch fire" op code. Normally they just patch this stuff with microcode and never really tell anybody, this time that won't work.

I'm not entirely convinced it was a mistake at all (dons tin foil hat), Intel have been making suspicious design decisions to their chips for a well now (think this, Intel Me, hidden instructions, etc). It seems clear to me that this security by obscurity approach is quite frankly crap.

Linus' releases need some sort of buffering before they can be considered stable, often distributions will apply their own patches on top. Also consider the scenario where Linus releases a bad kernel and no testing has been performed before rolling out to all Linux users.

I watched that spy demo. How does it know what memory location contains the password being typed?
