PC Processors

[OlegM]

Hello!

You created AMD Processor Vulnerabilities AMD-SB-7009

https://www.amd.com/en/resources/product-security/bulletin/amd-sb-7009.html

For example 4nd Gen AMD EPYC™ Processors

You write about Minimum version - GenoaPI 1.0.0.8 (2023-06-09)

https://www.amd.com/en/products/cpu/amd-epyc-9654

I think this record microcode of CPU GenoaPI 1.0.0.8 (2023-06-09)

Do I right about it?

I checked a few version microcode (for example in the microcode_ctl-2.1-73.20.el7_9.x86_64 )

Current microcode ( on the EPYC -9654)
(cat /proc/cpuinfo)

0xa101121

We can see different type or form record about microcode.

Could you please provide procedure or name of program for check version microcode on the AMD CPU ( in OS Centos / Debian/ Ubuntu).

Regards,
Oleg.M
