Yet another high severity attack against the Intel CPUs. Unpatched systems can leak SIMD, FP register state between privilege levels. These registers are used for private keys nowadays.
The cost of a patch is more expensive context switches because the fix has to unload and reload all SIMD, FP state.

Chromium devs are planning to enforce TLS protocol invariants by rolling new TLS 1.3 versions every six weeks.
According to the developers: "Every six weeks, we would randomly pick a new code point. These versions will otherwise be identical to TLS 1.3, save maybe minor details to separate keys and exercise allowed syntax changes. The goal is to pave the way for future versions of TLS by simulating them (“draft negative one”)."

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."
