Summary
amd64-microcode vulnerability
Details

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.
