"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."
- mrmondo 9y agoYeah that's a good one, hope they keep it updated / link to new info / posts as they come out.
- michaelermer 9y agoGoogle's post is newer and has more insights, the registry article is now outdated.
- ece 9y agoThe register has more details. Worth a read.
- olliej 9y agothe google site has the actual white papers detailing the attacks.
- ece 9y agoThe register has the tweet with actual code for spectre, and more details from the manufacturers and potential fixes. Seriosuly? They're both worth a read.
