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.

Insufficient validation of inputs in
SVC_MAP_USER_STACK in the ASP (AMD Secure Processor) bootloader may allow an
attacker with a malicious Uapp or ABL to send malformed or invalid syscall to
the bootloader resulting in a potential denial of service and loss of
integrity.
