5 | Caution: This module requires additional review when modified.\r |
6 | This driver will have external input - variable and ACPINvs data in SMM mode.\r | |
7 | This external input must be validated carefully to avoid security issue.\r | |
8 | \r | |
9 | PhysicalPresenceCallback() and MemoryClearCallback() will receive untrusted input and do some check.\r | |
