| 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. | 7.8 |
| 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 | 5.5 |
| 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. | 5.5 |
| 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. | 5.5 |
| 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. | 7.8 |
| 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. | 7.8 |
| 2021-11-16 | CVE-2021-26336 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products Insufficient bounds checking in System Management Unit (SMU) may cause invalid memory accesses/updates that could result in SMU hang and subsequent failure to service any further requests from other components. | 5.5 |
| 2021-11-16 | CVE-2021-26337 | Unspecified vulnerability in AMD products Insufficient DRAM address validation in System Management Unit (SMU) may result in a DMA read from invalid DRAM address to SRAM resulting in SMU not servicing further requests. | 5.5 |
| 2021-11-16 | CVE-2021-26312 | Exposure of Resource to Wrong Sphere vulnerability in AMD products Failure to flush the Translation Lookaside Buffer (TLB) of the I/O memory management unit (IOMMU) may lead an IO device to write to memory it should not be able to access, resulting in a potential loss of integrity. | 5.5 |
| 2021-11-16 | CVE-2021-26322 | Use of Insufficiently Random Values vulnerability in AMD products Persistent platform private key may not be protected with a random IV leading to a potential “two time pad attack”. | 7.5 |
