@rysiek I’m implying they have no idea what the consequences and probable fixes are of the bug not that they are lying. If they are referencing the MMU timing attack which much of it makes me think they are, then the misleading parts are all of it.
They way they portray it is nonsensical. They dont understand when kaslr is and is not useful....
@rysiek The patches look like they are protecting against the mmu attack only for kaslr when it is useless anyhow and not user space aslr where it is useful.
It is NOT paging out the kernel. This attack is present in amd but not across rings.
The entire article is a fuck. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5aa90a84589282b87666f92b6c3c917c8080a9bf
@rysiek it seems like they are mistaking an attack that tells you only if a page happens to be mapped or not at a given virtual memory address with an arbitrary kernel memory peek. The attack is the former and not very severe or useful.
