Intel chip security problems aren't going away, says Linux developer

According to Greg Kroah-Hartman, a Linux kernel maintainer, Intel designed speculative execution is that, while anticipating the next action for the CPU to take does indeed speed things up, it also exposes data along the way. That's bad enough on your own server, but when it breaks down the barriers between virtual machines (VM)s in cloud computing environments, it's a security nightmare.

Kroah-Hartman said, "These problems are going to be with us for a very long time, they're not going away. They're all CPU bugs, in some ways they're all the same problem," but each has to be solved in its own way. "MDS, RDDL, Fallout, Zombieland: They're all variants of the same basic problem."

And they're all potentially deadly for your security: "RIDL and Zombieload, for example, can steal data across applications, virtual machines, even secure enclaves. The last is really funny, because [Intel Software Guard Extensions (SGX)] is what supposed to be secure inside Intel ships" [but, it turns out it's] really porous. You can see right through this thing."
