Abstract
Systems and methods for preventing attachment of malign code to unused firmware memory are described. In some embodiments, an Information Handling System (IHS) may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to: read contents of a non-volatile memory (NVM); and determine that the NVM does not include malign code stored thereon, at least in part, by determining that selected memory locations in the NVM where firmware is not stored contain pre-determined values.
