Unified Extensible Firmware Interface System Management Mode Initialization Protections with System Management Interrupt Transfer Monitor Sandboxing |
| 摘要 |
An information handling system includes a processor configured to trap system management interrupts (SMIs) via a system management mode transfer monitor (STM), a first system resource, a SMI handler configured to operate within the STM, launch a first system management mode (SMM) virtual machine, load first SMM code for a first driver into the first SMM virtual machine, and associate the first SMM virtual machine with the first system resource and not with the second system resource. |
