Stemming from [1]AMD's recently acknowledged Zen 5 issue with the RDSEED instruction and [2]AMD releasing Zen 5 CPU microcode updates to address it, this week brought some additional microcode updates.

Merged this week to linux-firmware.git was [3]additional updates to the AMD Family 1Ah binary just two weeks after the prior round of updates as a result of the RDSEED issue.

While that commit to linux-firmware.git didn't acknowledge the changes, [4]a kernel patch noted additional fixed RDSEED microcode revisions. This new update fixes additional Zen 5 models to the RDSEED problem.

That patch for keeping track of the fixed RDSEED microcode revisions has now been submitted as part of this week's [5]x86 fixes heading into the Linux 6.18-rc6 kernel release on Sunday.

With this week's x86 fixes for Linux 6.18 is also [6]this patch . [7]Prominent Linux kernel engineer and former longtime Intel employee Kirill Shutemov is now going by Kiryl Shutsemau moving forward to use the transliteration from the Belarusian language rather than Russian.

Linux 6.18-rc6 is due out tomorrow while Linux 6.18 stable should be out around the end of November.
