Insufficient syscall input validation in the ASP Bootloader may allow a privileged attacker to read memory outside the bounds of a mapped register potentially leading to a denial of service.

TOCTOU in the ASP may allow a physical attacker to write beyond the buffer bounds, potentially leading to a loss of integrity or denial of service.

Insufficient bounds checking in ASP (AMD Secure Processor) firmware while handling BIOS mailbox commands, may allow an attacker to write partially-controlled data out-of-bounds to SMM or SEV-ES regions which may lead to a potential loss of integrity and availability.

Insufficient input validation in SYS_KEY_DERIVE system call in a compromised user application or ABL may allow an attacker to corrupt ASP (AMD Secure Processor) OS memory which may lead to potential arbitrary code execution.

Insufficient validation in ASP BIOS and DRTM commands may allow malicious supervisor x86 software to disclose the contents of sensitive memory which may result in information disclosure.

Failure to verify the mode of CPU execution at the time of SNP_INIT may lead to a potential loss of memory integrity for SNP guests.
