| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2022-05-11 | CVE-2021-46744 | Information Exposure Through Discrepancy vulnerability in AMD products An attacker with access to a malicious hypervisor may be able to infer data values used in a SEV guest on AMD CPUs by monitoring ciphertext values over time. | 6.5 |
| 2022-05-10 | CVE-2021-26324 | Unspecified vulnerability in AMD products A bug with the SEV-ES TMR may lead to a potential loss of memory integrity for SNP-active VMs. | 7.8 |
| 2022-05-10 | CVE-2021-26332 | Unspecified vulnerability in AMD products Failure to verify SEV-ES TMR is not in MMIO space, SEV-ES FW could result in a potential loss of integrity or availability. | 7.1 |
| 2022-05-10 | CVE-2021-26353 | Improper Initialization vulnerability in AMD products Failure to validate inputs in SMM may allow an attacker to create a mishandled error leaving the DRTM UApp in a partially initialized state potentially resulting in loss of memory integrity. | 7.8 |
| 2022-05-10 | CVE-2021-26370 | Improper Input Validation vulnerability in AMD products Improper validation of destination address in SVC_LOAD_FW_IMAGE_BY_INSTANCE and SVC_LOAD_BINARY_BY_ATTRIB in a malicious UApp or ABL may allow an attacker to overwrite arbitrary bootloader memory with SPI ROM contents resulting in a loss of integrity and availability. | 7.1 |
| 2022-05-10 | CVE-2021-46771 | Unspecified vulnerability in AMD products Insufficient validation of addresses in AMD Secure Processor (ASP) firmware system call may potentially lead to arbitrary code execution by a compromised user application. | 7.8 |
| 2022-02-04 | CVE-2020-12966 | Information Exposure vulnerability in AMD products AMD EPYC™ Processors contain an information disclosure vulnerability in the Secure Encrypted Virtualization with Encrypted State (SEV-ES) and Secure Encrypted Virtualization with Secure Nested Paging (SEV-SNP). | 5.5 |
| 2021-12-10 | CVE-2021-26340 | Unspecified vulnerability in AMD products A malicious hypervisor in conjunction with an unprivileged attacker process inside an SEV/SEV-ES guest VM may fail to flush the Translation Lookaside Buffer (TLB) resulting in unexpected behavior inside the virtual machine (VM). | 8.4 |
| 2021-11-16 | CVE-2020-12944 | Improper Input Validation vulnerability in AMD products Insufficient validation of BIOS image length by ASP Firmware could lead to arbitrary code execution. | 7.8 |
| 2021-11-16 | CVE-2020-12946 | Improper Input Validation vulnerability in AMD products Insufficient input validation in ASP firmware for discrete TPM commands could allow a potential loss of integrity and denial of service. | 7.1 |
