Abstract

An information handling system includes a basic input/output system configured to update an attribute of a system-wide firmware downgrade security policy prior to booting to an operating system of the information handling system. The attribute of the system-wide firmware downgrade security policy is used to determine whether to allow or to disallow downgrade of a firmware to a version. A processor may perform the downgrade of the firmware, wherein the downgrade of the firmware includes the processor further configured to check the attribute of the system-wide firmware downgrade security policy and to store a firmware image in a scratchpad. If the attribute of the system-wide firmware downgrade security policy allows the downgrade of the firmware to the version, then the processor may continue with the downgrade of the firmware otherwise discard the firmware image in the scratchpad.
