| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-01-11 | CVE-2021-26409 | Classic Buffer Overflow vulnerability in AMD Milanpi Firmware 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. | 7.8 |
| 2023-01-11 | CVE-2021-46767 | Improper Input Validation vulnerability in AMD Milanpi Firmware and Romepi Firmware 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. | 6.1 |
| 2023-01-11 | CVE-2021-46768 | Out-of-bounds Read vulnerability in AMD Milanpi Firmware and Romepi Firmware 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. | 5.5 |
| 2023-01-11 | CVE-2021-46779 | Out-of-bounds Write vulnerability in AMD products 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. | 7.1 |
| 2023-01-11 | CVE-2021-46791 | Out-of-bounds Write vulnerability in AMD Milanpi Firmware 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. | 5.5 |
| 2023-01-11 | CVE-2021-46795 | Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products 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. | 4.7 |
| 2023-01-11 | CVE-2022-23813 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD Milanpi-Sp3 Firmware and Romepi Firmware 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. | 5.3 |
| 2023-01-11 | CVE-2022-23814 | Improper Input Validation vulnerability in AMD Milanpi-Sp3 Firmware Failure to validate addresses provided by software to BIOS commands may result in a potential loss of integrity of guest memory in a confidential compute environment. | 5.3 |
| 2023-01-11 | CVE-2023-20522 | Improper Input Validation vulnerability in AMD Milanpi Firmware and Romepi Firmware Insufficient input validation in ASP may allow an attacker with a malicious BIOS to potentially cause a denial of service. | 7.5 |
| 2023-01-11 | CVE-2023-20523 | Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products 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. | 5.7 |
