USN-7077-1: AMD Microcode vulnerability
First published: Mon Oct 21 2024(Updated: )
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.
