Intel processor chip defect Kernel memory leaking

A place to discuss and share information regarding Intel's design flaw in the x-86-64 based chips. Basically everything they made going back at least 10 years.

Here is one article:

Kernel-memory-leaking Intel processor design flaw forces Linux, Windows redesign/


Quoting 
Similar operating systems, such as Apple's 64-bit macOS, will also need to be updated – the flaw is in the Intel x86-64 hardware, and it appears a microcode update can't address it. It has to be fixed in software at the OS level, or go buy a new processor without the design blunder.


Quoting 
Crucially, these updates to both Linux and Windows will incur a performance hit on Intel products. The effects are still being benchmarked, however we're looking at a ballpark figure of five to 30 per cent slow down, depending on the task and the processor model. More recent Intel chips have features – such as PCID – to reduce the performance hit. Your mileage may vary.

I spoke to Scott yesterday, owner of TradingComputers.com, about my machines and he confirmed it's my problem too....lol. He said Intel has 90% market share.

Hi Sam, what makes you think desktop/laptop class is not affected?

Obviously I am not speaking for Sam.... all I can figure from his comment is that our machines will run faster (like "normal" and how we are used to) up until the point of the OS software major reworking, probably with the month here, and THEN we will have nice somewhat slower machines to lose money on.....lol

Well he's not stupid

Would be useful if and when they publish the specific processors affected.

Hi Sam, what makes you think desktop/laptop class is not affected?

Their processors are affected but the probability of being impacted is lower than on cloud providers services (AWS, Google CE, ...). On your own PC you're usually the only user so you have to have a virus or a malware activating this thing. On AWS EC2 a client VM could impact the hypervisor (the physical server) and impacting the other clients.
So the main risk is for some cloud providers, for a "normal" user it's as risky a getting a bad malware. The Wannacry ransomware was much worst, but let's see what's happening next.
