Take a look at /proc/cpuinfo Your CPU code will be the: 'cpu family'-'model'-'stepping' So, for example, on my computer, that is: 6 - 58 - 9 Now, Intel uses the hex for that, so lets get it easily: $ printf '%02x-%02x-%02x\n' 6 58 9 06-3a-09 So, lets look at the github page for the intel microcode releases: https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/releases I don't see my CPU ID mentioned there, so the latest microcode doesn't seem to have been updated for my CPU. Either the CPU isn't vulnerable or they didn't address it. But if I look at another computer: $ printf '%02x-%02x-%02x\n' 6 94 3 06-5e-03 I do see it. And the microcode_ctl update does appear to be applying an update. Actually, that one is a RHEL system and in its notes, it says that it doesn't apply the microcode update because it causes hangs. Hopefully this will help you research your own system. -- Jonathan Billings <billings@xxxxxxxxxx> _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
