Improper access control settings in ASP Bootloader may allow an attacker to corrupt the return address causing a stack-based buffer overrun potentially leading to arbitrary code execution.

Insufficient input validation on the model specific register: VM_HSAVE_PA may potentially lead to loss of SEV-SNP guest memory integrity.

Improper input validation in ABL may enable an attacker with physical access, to perform arbitrary memory overwrites, potentially leading to a loss of integrity and code execution.

Insufficient syscall input validation in the ASP Bootloader may allow a privileged attacker to execute arbitrary DMA copies, which can lead to code execution.

Improper validation of DRAM addresses in SMU may allow an attacker to overwrite sensitive memory locations within the ASP potentially resulting in a denial of service.

Insufficient input validation in the SMU may enable a privileged attacker to write beyond the intended bounds of a shared memory buffer potentially leading to a loss of integrity.

Insufficient input validation in the SMU may allow an attacker to corrupt SMU SRAM potentially leading to a loss of integrity or denial of service.

Failure to validate the length fields of the ASP (AMD Secure Processor) sensor fusion hub headers may allow an attacker with a malicious Uapp or ABL to map the ASP sensor fusion hub region and overwrite data structures leading to a potential loss of confidentiality and integrity.

Insufficient bounds checking in ASP (AMD Secure Processor) may allow for an out of bounds read in SMI (System Management Interface) mailbox checksum calculation triggering a data abort, resulting in a potential denial of service.

Insufficient validation in parsing Owner's Certificate Authority (OCA) certificates in SEV (AMD Secure Encrypted Virtualization) and SEV-ES user application can lead to a host crash potentially resulting in denial of service.
