A privileged attacker can prevent delivery of debug exceptions to SEV-SNP guests potentially resulting in guests not receiving expected debug information.

Improper address validation in ASP with SNP enabled may potentially allow an attacker to compromise guest memory integrity.

SMM configuration may not be immutable, as intended, when SNP is enabled resulting in a potential limited loss of guest memory integrity.

Insufficient DRAM address validation in System Management Unit (SMU) may allow an attacker to read/write from/to an invalid DRAM address, potentially resulting in denial-of-service.

Failure to validate the value in APCB may allow a privileged attacker to tamper with the APCB token to force an out-of-bounds memory read potentially resulting in a denial of service.

A potential power side-channel vulnerability in AMD processors may allow an authenticated attacker to monitor the CPU power consumption as the data in a cache line changes over time potentially resulting in a leak of sensitive information.
