| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-01-11 | CVE-2021-26316 | Improper Input Validation vulnerability in AMD products 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. | 7.8 |
| 2023-01-11 | CVE-2021-26398 | Out-of-bounds Write vulnerability in AMD products Insufficient input validation in SYS_KEY_DERIVE 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 arbitrary code execution. | 7.8 |
| 2023-01-11 | CVE-2021-26402 | Out-of-bounds Write vulnerability in AMD products Insufficient bounds checking in ASP (AMD Secure Processor) firmware while handling BIOS mailbox commands, may allow an attacker to write partially-controlled data out-of-bounds to SMM or SEV-ES regions which may lead to a potential loss of integrity and availability. | 7.1 |
| 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-2021-46779 | 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-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-2023-20529 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products Insufficient bound checks in the SMU may allow an attacker to update the from/to address space to an invalid value potentially resulting in a denial of service. | 7.5 |
| 2023-01-11 | CVE-2023-20530 | Improper Input Validation vulnerability in AMD products Insufficient input validation of BIOS mailbox messages in SMU may result in out-of-bounds memory reads potentially resulting in a denial of service. | 7.5 |
| 2023-01-11 | CVE-2023-20531 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products Insufficient bound checks in the SMU may allow an attacker to update the SRAM from/to address space to an invalid value potentially resulting in a denial of service. | 7.5 |
| 2022-11-15 | CVE-2022-29277 | Out-of-bounds Write vulnerability in multiple products Incorrect pointer checks within the the FwBlockServiceSmm driver can allow arbitrary RAM modifications During review of the FwBlockServiceSmm driver, certain instances of SpiAccessLib could be tricked into writing 0xff to arbitrary system and SMRAM addresses. | 8.8 |
