Insufficient bounds checking in SEV-ES may allow an attacker to corrupt Reverse Map table (RMP) memory, potentially resulting in a loss of SNP (Secure Nested Paging) memory integrity.
Insufficient input validation in the ASP may allow an attacker with physical access, unauthorized write access to memory potentially leading to a loss of integrity or denial of service.
Insufficient input validation in SEV firmware may allow an attacker to perform out-of-bounds memory reads within the ASP boot loader, potentially leading to a denial of service.
Insufficient input validation in SVC_ECC_PRIMITIVE 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 loss of integrity and availability.
Insufficient input validation during parsing of the System Management Mode (SMM) binary may allow a maliciously crafted SMM executable binary to corrupt Dynamic Root of Trust for Measurement (DRTM) user application memory that may result in a potential denial of service.
A TOCTOU (time-of-check to time-of-use) vulnerability exists where an attacker may use a compromised BIOS to cause the TEE OS to read memory out of bounds that could potentially result in a denial of service.
Failure to validate the communication buffer and communication service in the BIOS may allow an attacker to tamper with the buffer resulting in potential SMM (System Management Mode) arbitrary code execution.
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.
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 validate the integer operand in ASP (AMD Secure Processor) bootloader may allow an attacker to introduce an integer overflow in the L2 directory table in SPI flash resulting in a potential denial of service.
