• CVE-2023-20522, published 2023-01-11. High severity, CVSS 7.5. EPSS: 0.6% chance of exploitation in the next 30 days. Insufficient input validation in ASP may allow an attacker with a malicious BIOS to potentially cause a denial of service.
• CVE-2022-23813, published 2023-01-11. Medium severity, CVSS 5.3. EPSS: 0.5% chance of exploitation in the next 30 days. The software interfaces to ASP and SMU may not enforce the SNP memory security policy resulting in a potential loss of integrity of guest memory in a confidential compute environment.
• CVE-2021-46767, published 2023-01-11. Medium severity, CVSS 6.1. EPSS: 0.3% chance of exploitation in the next 30 days. 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.
• CVE-2021-26407, published 2023-01-11. Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days. A randomly generated Initialization Vector (IV) may lead to a collision of IVs with the same key potentially resulting in information disclosure.
• CVE-2021-46779, published 2023-01-11. High severity, CVSS 7.1. EPSS: 0.2% chance of exploitation in the next 30 days. 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…
• CVE-2021-46768, published 2023-01-11. Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days. 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.
