| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2021-11-16 | CVE-2020-12961 | Unspecified vulnerability in AMD products A potential vulnerability exists in AMD Platform Security Processor (PSP) that may allow an attacker to zero any privileged register on the System Management Network which may lead to bypassing SPI ROM protections. | 4.6 |
| 2021-11-16 | CVE-2021-26315 | Insufficient Verification of Data Authenticity vulnerability in AMD products When the AMD Platform Security Processor (PSP) boot rom loads, authenticates, and subsequently decrypts an encrypted FW, due to insufficient verification of the integrity of decrypted image, arbitrary code may be executed in the PSP when encrypted firmware images are used. | 4.6 |
| 2021-11-16 | CVE-2021-26320 | Improper Certificate Validation vulnerability in AMD products Insufficient validation of the AMD SEV Signing Key (ASK) in the SEND_START command in the SEV Firmware may allow a local authenticated attacker to perform a denial of service of the PSP | 2.1 |
| 2021-11-16 | CVE-2021-26321 | Command Injection vulnerability in AMD products Insufficient ID command validation in the SEV Firmware may allow a local authenticated attacker to perform a denial of service of the PSP. | 4.9 |
| 2021-11-16 | CVE-2021-26323 | Improper Input Validation vulnerability in AMD products Failure to validate SEV Commands while SNP is active may result in a potential impact to memory integrity. | 4.6 |
| 2021-11-16 | CVE-2021-26325 | Improper Input Validation vulnerability in AMD products Insufficient input validation in the SNP_GUEST_REQUEST command may lead to a potential data abort error and a denial of service. | 2.1 |
| 2021-11-16 | CVE-2021-26327 | Exposure of Resource to Wrong Sphere vulnerability in AMD products Insufficient validation of guest context in the SNP Firmware could lead to a potential loss of guest confidentiality. | 2.1 |
| 2021-11-16 | CVE-2021-26330 | Out-of-bounds Write vulnerability in AMD products AMD System Management Unit (SMU) may experience a heap-based overflow which may result in a loss of resources. | 2.1 |
| 2021-11-16 | CVE-2021-26331 | Unspecified vulnerability in AMD products AMD System Management Unit (SMU) contains a potential issue where a malicious user may be able to manipulate mailbox entries leading to arbitrary code execution. | 7.2 |
| 2021-11-16 | CVE-2021-26335 | Unspecified vulnerability in AMD products Improper input and range checking in the AMD Secure Processor (ASP) boot loader image header may allow an attacker to use attacker-controlled values prior to signature validation potentially resulting in arbitrary code execution. | 7.2 |
