There is a critical hardware bug in the Intel chips, which enables a user level process to access kernel address space, thus read other processes memory. Cloud providers and OS makers are preparing software patches, but the performance penalty could be significant. According to the Wired:
"[researchers] confirmed that when Intel processors perform that speculative execution, they don't fully segregate processes that are meant to be low-privilege and untrusted from the highest-privilege memory in the computer's kernel. That means a hacker can trick the processor into allowing unprivileged code to peek into the kernel's memory with speculative execution."
