Another day, another Intel hardware security bug. This time it's called Microarchitectural Data Sampling (or MDS for short) and has been proven to work on Intel's Ivy bridge, Haswell, Skylake and Kaby Lake CPU's. This vulnerability is particularly concerning because it allows an attacker to access privileged kernel-mode information. I'm wondering if my aging Westmere-EP server and my Sandy-E desktop are affected. So, how long before all CPU's return to being in-order designs? Out of order designs certainly have some real performance benefits, but it seems like they inevitably lead to vulnerabilities.
