Re: Meltdown and Spectre
There are patches already available for Linux, Microsoft is releasing a patch next Tuesday with the regular monthly Patch Tuesday updates.
I've not heard yet on Apple, but they're working on a patch too.
This (Spectre) isn't an OS bug, it's a processor architecture bug that can be mitigated through the OS, so it affects EVERY system that has a processor that can do speculative execution. That's Intel, AMD, ARM, pretty much every processor that's been built the past 20 years. That includes your router and your phone. It's icky.
