Fedora 37: Essential CPU Microcode Update for Security Vulnerabilities

fedora
Calendar Grey November 23, 2023
Dist Fedora Esm H88
Boost Fedora 37 using microcode_ctl version 2.1-42, which resolves recent processor vulnerabilities reflected in the updates.
- Update to upstream 2.1-42

Summary

The microcode_ctl utility is a companion to the microcode driver written

by Tigran Aivazian .

The microcode update is volatile and needs to be uploaded on each system

boot i.e. it doesn't reflash your cpu permanently, reboot and it reverts

back to the old microcode.
