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

Recommended Posts

Basically, the intel processors in many computers, (a great majority of them, probably your own as well), have a major design flaw There are reports that it can range from 5%-30% and there is a rumor going around, a specfic generation of intel processors, skylake (6700, 6700k, 6600k etc.) can have loses up to 60%. These flaws are present in processors from over 10 years ago.

 

"At worst, the hole could be abused by programs and logged-in users to read the contents of the kernel's memory. Suffice to say, this is not great. The kernel's memory space is hidden from user processes and programs because it may contain all sorts of secrets, such as passwords, login keys, files cached from disk, and so on. Imagine a piece of JavaScript running in a browser, or malicious software running on a shared public cloud server, able to sniff sensitive kernel-protected data."

 

AMD users should NOT be affected by this

 

"AMD processors are not subject to the types of attacks that the kernel page table isolation feature protects against. The AMD microarchitecture does not allow memory references, including speculative references, that access higher privileged data when running in a lesser privileged mode when that access would result in a page fault."

I wouldn't freak out, as the embargo on this information does not lift until January 4th. and we probably won't have a grasp on this situation until later in the month.

 

 

I just bought an 8700k too. Fucking reeeeeeeeeee.

Well that's no good.
