That's THE definitive place for more info on the vulnerabilities.. but here's another really great video by my buddies at Red Hat that really break it down:

 I don't normally send out security announcements.. but this is so huge it demands some extra attention..

Here's a really great security bulletin by a good X-Racker friend of mine (now a security lead at Red Hat) on the big processor/kernel Side-Channel attack vectors (by Meltdown/Spectre).
https://access.redhat.com/security/vulnerabilities/speculativeexecution

If you run Red Hat base distros, stay tuned to the Advisory/Update column of the "Resolve" tab of this super critical security bulletin.


TL;DR
The packages you'll want to watch for updates on are kernel, libvirt and qemu-kvm (as well as kernel-rt and dracut on RHEL7):

Post any of your findings, tips or suggestions here please.. we're all in this one for the long term!


p.s. Invite security friends to both this list:  http://lists.rbtc.tech/mailman/listinfo/security-discuss
and the main [Security-Announce] list:  http://lists.rbtc.tech/mailman/listinfo/security-announce
Both run the mailman email list server, and as such have archives that are google indexed, and thus VERY useful for recalling useful things you can't quite remember.. :)
