Your kernel is up to date for SRBDS mitigation) * SRBDS mitigation control is enabled and active: NO > STATUS: NOT VULNERABLE (your CPU vendor reported your CPU model as not vulnerable) This was reported fixed in microcode_ctl-2.1-39.fc32 as shown in the links you've provided. Do you have that package updated? -- The key to getting good answers is to ask good questions. _______________________________________________ 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
