Known Vulnerabilities
CVE-2023-31315
Improper validation in a model specific register (MSR) could allow a malicious program with ring0 access to modify SMM configuration while SMI lock is enabled, potentially leading to arbitrary code execution.
CVE-2024-21980
Improper restriction of write operations in SNP firmware could allow a malicious hypervisor to potentially overwrite a guest's memory or UMC seed resulting in loss of confidentiality and integrity.
CVE-2024-21978
Improper input validation in SEV-SNP could allow a malicious hypervisor to read or overwrite guest memory potentially leading to data leakage or data corruption.
CVE-2023-31355
Improper restriction of write operations in SNP firmware could allow a malicious hypervisor to overwrite a guest's UMC seed potentially allowing reading of memory from a decommissioned guest.
CVE-2023-20587
Improper Access Control in System Management Mode (SMM) may allow an attacker access to the SPI flash potentially leading to arbitrary code execution.
CVE-2023-20566
Improper address validation in ASP with SNP enabled may potentially allow an attacker to compromise guest memory integrity.
CVE-2021-46766
Improper clearing of sensitive data in the ASP Bootloader may expose secret keys to a privileged attacker accessing ASP SRAM, potentially leading to a loss of confidentiality.
