IOMMU improperly handles certain special address
ranges with invalid device table entries (DTEs), which may allow an attacker
with privileges and a compromised Hypervisor to
induce DTE faults to bypass RMP checks in SEV-SNP, potentially leading to a
loss of guest integrity.

Improper re-initialization of IOMMU during the DRTM event
may permit an untrusted platform configuration to persist, allowing an attacker
to read or modify hypervisor memory, potentially resulting in loss of
confidentiality, integrity, and availability.
