<snip> A new microcode for your CPU should be inside of /usr/lib/firmware/amd-ucode/microcode_amd_fam15h.bin since it says 'family: 0x15' in your output.There is a little program on https://github.com/AMDESE/amd_ucode_info to look into the microcode file. For the package amd64-microcode on Debian testing version 3.20240820.1 it yields:
$ amd_ucode_info.py /usr/lib/firmware/amd-ucode/microcode_amd_fam15h.bin Microcode patches in xx/usr/lib/firmware/amd-ucode/microcode_amd_fam15h.bin: Family=0x15 Model=0x01 Stepping=0x02: Patch=0x0600063e Length=2592 bytes Family=0x15 Model=0x02 Stepping=0x00: Patch=0x06000852 Length=2592 bytes Family=0x15 Model=0x10 Stepping=0x01: Patch=0x06001119 Length=2592 bytes So yes, your CPU microcode is up-to-date.
