Intel's massive MDS vulnerability has forced Google to slow Chrome OS, but a fix is coming

Google has pushed out a Chrome OS update (version 74) with a quick fix for the new MDS vulnerabilities that can let a bad actor read privileged portions of memory.

That's the good news; the bad is that to make sure any exploits can't affect Chrome users, Hyper-Threading is now disabled by default.

This changes how the processor schedules its jobs and the fill and store buffer in the CPU cache won't be able to be read by outside software.

If you're unsure of what Hyper-Threading is or why Google disabled it to mitigate a side-channel data vulnerability, then you should leave things alone and trust the pros.

You might notice some slow down in your normal work, but unless you're really pushing things with Linux applications or running heavy web apps, you'll be fine.

I'm not noticing any difference while working with multiple tabs open, including a YouTube playlist of my favorite songs.
