Spectre Variant 2 on CentoS 6.8

Post by polax » 2018/03/09 04:14:54

I have updated my CentOS 6 with "yum update" and restarted, but spectre-meltdown-checker is showing vulnerability to Variant 2:

How can I fix it?

Your kernel is compiled with IBRS but your CPU microcode is lacking support to successfully mitigate the vulnerability.

Ask Intel for a microcode update or your hardware vendor for a BIOS update that includes this microcode update.

Up to now, Intel has only come up with a microcode update for Skylake CPUs and you can only get it if your hardware vendor offers a BIOS update including it.

It is not included here: https://downloadcenter.intel.com/downlo ... -Data-File

Moved to CentOS 6 Security forum.
CentOS 5 died in March 2017 - migrate NOW!
