A TOCTOU (Time-Of-Check-Time-Of-Use) in SMM may allow
an attacker with ring0 privileges and access to the
BIOS menu or UEFI shell to modify the communications buffer potentially
resulting in arbitrary code execution.

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.

An out of bounds memory write when processing the AMD
PSP1 Configuration Block (APCB) could allow an attacker with access the ability
to modify the BIOS image, and the ability to sign the resulting image, to
potentially modify the APCB block resulting in arbitrary code execution.
