Meltdown exploits Intel's branch predictor behavior which is not present in other manufacturers' CPUs.
- zurn 9y agoDepends on what you mean by Meltdown. The paper defines Meltdown ambigiously, the author variously refer to the Meltdown attack, the Meltdown exploit (= PoC), the Meltdown bug (= vulnerability). The current PoC created by the researchers doesn't work on other manufacturer's CPU's, but the vulnerability and the Meltdown class of attacks should work on other manufacturer's CPUs. Or at least we don't know any reason it shouldn't. The authors' "toy example" works on AMD and ARM too. (See the section 6.4 in the paper).
