We don't think we can send any related AMD CVE ID or IDs here because
this microcode isn't an open-source product:
https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/LICENSE.amd-ucode
"You may not reverse engineer, decompile, or disassemble this Software
or any portion thereof."
CVE IDs for AMD products are available from cve-assign@...re.org (we
understand that the 0x06000832 information is directly relevant to use
of open-source products; also, it's at least conceivable that someone
will announce a security update to an open-source product with a
workaround for the behavior, or for the existence, of 0x06000832).
