See > <https://www.intel.com/content/www/us/en/developer/articles/technical/software-security-guidance/best-practices/microcode-update-guidance.html>. To check whether is the latest microcode installed I followed the instructions at the "Debugging" section: https://www.intel.com/content/www/us/en/developer/articles/technical/software-security-guidance/best-practices/microcode-update-guidance.html#inpage-nav-1-2 but I've a AMD CPU not an Intel one, I tried the command reported in that section, then adjusting it for AMD microcode: ~$ od -t x4 /lib/firmware/amd-ucode/microcode_amd_fam15h.bin 0000000 00414d44 00000000 00000040 00600f20 0000020 00000000 00000000 00006020 00610f01 0000040 00000000 00000000 00006101 00600f12 0000060 00000000 00000000 00006012 00000000 0000100 00000000 00000000 00000000 00000001 0000120 00000a20 02072018 0600063e 00008002 0000140 00000000 00000000 00000000 00006012 0000160 00000000 9a6f0301 4818af19 bafc759b 0000200 6fd1c6b5 236d9140 c65e7559 fc6c6c9c <snip> I don't know how to interpret the output, maybe that command doesn't apply for AMD microcode, any hints?
