| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-05-09 | CVE-2021-26397 | Unspecified vulnerability in AMD products Insufficient address validation, may allow an attacker with a compromised ABL and UApp to corrupt sensitive memory locations potentially resulting in a loss of integrity or availability. | 7.1 |
| 2023-05-09 | CVE-2021-46762 | Improper Input Validation vulnerability in AMD products 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. | 9.1 |
| 2023-05-09 | CVE-2021-46763 | Out-of-bounds Write vulnerability in AMD products 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. | 7.5 |
| 2023-05-09 | CVE-2021-46764 | Out-of-bounds Write vulnerability in AMD products 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. | 7.5 |
| 2023-05-09 | CVE-2021-46769 | Improper Input Validation vulnerability in AMD products Insufficient syscall input validation in the ASP Bootloader may allow a privileged attacker to execute arbitrary DMA copies, which can lead to code execution. | 8.8 |
| 2023-05-09 | CVE-2021-46775 | Improper Input Validation vulnerability in AMD products 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. | 6.8 |
| 2023-05-09 | CVE-2022-23818 | Improper Input Validation vulnerability in AMD products Insufficient input validation on the model specific register: VM_HSAVE_PA may potentially lead to loss of SEV-SNP guest memory integrity. | 7.5 |
| 2023-05-09 | CVE-2023-20520 | Out-of-bounds Write vulnerability in AMD products 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. | 9.8 |
| 2023-05-09 | CVE-2023-20524 | Out-of-bounds Write vulnerability in AMD products An attacker with a compromised ASP could possibly send malformed commands to an ASP on another CPU, resulting in an out of bounds write, potentially leading to a loss a loss of integrity. | 7.5 |
| 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 |
