3rd gen EPYC will get microcode updates.
1st and 2nd gen will not get updtes.
4th EPYC are not affected
Comment 4 Marcus Meissner 2023-11-15 08:00:08 UTC 
now public

Comment 5 Takashi Iwai 2023-11-15 11:34:06 UTC 
Is the new ucode already upstreamed?  The only recent change in linux-firmware tree is the CPU ucode update on Oct 19.

SB-3005:
*       Patches have been upstream for some time and were initially included here: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/amd-ucode?id=b250b32ab1d044953af2dc5e790819a7703b7ee6
o       Though please note that patches for some of these revisions have been updated further since that commit.
Comment 9 Takashi Iwai 2023-11-29 15:53:23 UTC 
I updated kernel-firmware package to the latest state (20231128) for TW, SLE15-SP6 and ALP.

Will backport to older releases, too.
Comment 10 Takashi Iwai 2023-11-29 17:00:37 UTC 
Now amd-ucode (in kernel-firmware) got updated for SLE15-SP5, SLE15-SP4, SLE15-SP3, SLE15-SP1, SLE15, SLE12-SP4 and SLE12-SP2.

Reassigned back to security team.
