Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

AMD x86 CPU microcode is maintained as part of the linux-firmware package, reassigning.
Comment 2 Peter Robinson 2026-06-12 21:21:18 UTC 
Another pointless zero research bug from RH security (why do people pay for this exactly). This isn't a CPU patchable firmware and hence isn't dealt with by linux kernel applyable firmware AT ALL. It has to be provided by a early boot vendor firmware.

PLEASE red hat security please do some BASIC research for your bugs, at least for your paid customers!
