System and method for secure smi memory services

A method for providing secure SMI memory services, comprising:

• requesting one or more actions;
• triggering an SMI interrupt;
• entering SMM;
• initiating an SMI driver associated with the SMI interrupt;
• initiating one or more SMI handlers registered to the SMI driver associated with the triggered SMI interrupt;
• requesting for each of the SMI handlers an allocation of one or more blocks of memory from a secure SMI memory services driver, wherein the one or more blocks of memory is requested from a memory pool associated with SMM memory;
• performing one or more actions by the SMI handler, wherein the SMI handler uses one or more of the allocated blocks of memory;
• and
• performing a secure erase of each block of memory by the secure SMI memory services driver after performing the one or more actions.

An information handling system for securing SMI memory services, comprising:

• a processor;
• and
• a memory, wherein the memory includes executable instructions, that when executed, cause the processor to:
• request one or more actions;
• trigger an SMI interrupt enter SMM;
• initiate an SMI driver associated with the SMI interrupt;
• initiate one or more SMI handlers registered to the SMI driver associated with the triggered SMI interrupt;
• request for each of the SMI handlers an allocation of one or more blocks of memory from a secure SMI memory services driver, wherein the one or more blocks of memory is requested from a memory pool associated with SMM memory;
• perform one or more actions by the SMI handler, wherein the SMI handler uses one or more of the allocated blocks of memory;
• and
• perform a secure erase of each block of memory by the secure SMI memory services driver after performing the one or more actions.
