Prevent invalid DMAR ACPI table dereference if the table is not found. Signed-off-by: Michael Kubacki <michael.kubacki@microsoft.com>
…parison SmmAccessDxe: `mSmmAccess.NumberRegions` is a `UINTN` while the loop index variable compared against it is a `UINT8`. This can lead to an overflow of the loop index for `mSmmAccess.NumberRegions` for values larger than `UINT8_MAX`. This change makes `Index` a `UINTN` to match in width. PeiSmmAccessLib: Fixes a similar `UINT8` loop index issue. Signed-off-by: Michael Kubacki <michael.kubacki@microsoft.com>
