Apparently there’s been a CPU flaw found in every Intel chip made for the past decade which will require OS patching, and that patching is going to result in a serious performance hit. It basically negates ASLR and can be exploited from any application. It can even allow VMs to peek on each other.
I saw something in the Ars Technica article that the patch may cause a slight performance hit on AMD systems.
Intel is not having a good couple of years. This comes on top of the Intel Management Engine concerns, the Clock Bug that hit a lot of embedded systems, and another issue or two.
Over on the CrazyAppleRumors side, I’m kind of wondering if people are not quite so crazy in thinking that Apple might try to jump ship to their own ARM-based processors, even though that would prevent Bootcamp and similar.
The non-Intel one theoretically hits a lot of processors, I think. It’s basically built around “Get the processor to do branch prediction, then grab data from the unused branch” which is possible to exploit, but I’m guessing it will be uncommon. Bad side is the only fix will probably involve new hardware.
Still, Intel has had a bad couple of years. I’m replacing devices with the bad clock chip bug, and then we’ll have to do other gear… Anything x86-64 compatible theoretically has this new flaw.
