Improper validation in a model specific register (MSR) could allow a malicious program with ring0 access to modify SMM configuration while SMI lock is enabled, potentially leading to arbitrary code execution.

 https://vulnerability.circl.lu/vuln/usn-7077-1 USN-7077-1 — amd64-microcode vulnerability 2026-09-30T16:14:43.387733+00:00

Affected: Ubuntu:Pro:16.04:LTS: amd64-microcode, Ubuntu:Pro:18.04:LTS: amd64-microcode, Ubuntu:20.04:LTS: amd64-microcode, Ubuntu:22.04:LTS: amd64-microcode, Ubuntu:24.04:LTS: amd64-microcode

Enrique Nissim and Krzysztof Okupski discovered that some AMD processors did not properly restrict access to the System Management Mode (SMM) configuration when the SMM Lock was enabled. A privileged local attacker could possibly use this issue to further escalate their privileges and execute arbitrary code within the processor's firmware layer.
