AMD has issued microcode updates for a wide range of server and desktop CPUs to address a vulnerability that could allow attackers to bypass protections for the System Management Mode (SMM) and execute malicious code in the low-level firmware outside of the OS.

The flaw could be used to deploy stealthy boot-level rootkits in UEFI that are very hard to detect or remove.

The vulnerability (CVE-2023-31315) impacts nearly all AMD EPYC series and Ryzen series CPUs.
