|---|---|---|---|---|---|
| CVE-2021-46744 | 1 Amd | 198 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 195 more | 2023-08-08 | 2.1 LOW | 6.5 MEDIUM |
| 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. | |||||
| CVE-2021-26355 | 1 Amd | 48 Epyc 7003, Epyc 7003 Firmware, Epyc 72f3 and 45 more | 2023-08-08 | N/A | 5.5 MEDIUM |
| Insufficient fencing and checks in System Management Unit (SMU) may result in access to invalid message port registers that could result in a potential denial-of-service. | |||||
| CVE-2020-12954 | 1 Amd | 116 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 113 more | 2022-07-08 | 2.1 LOW | 5.5 MEDIUM |
| A side effect of an integrated chipset option may be able to be used by an attacker to bypass SPI ROM protections, allowing unauthorized SPI ROM modification. | |||||
| CVE-2021-26336 | 1 Amd | 88 Epyc 7002, Epyc 7002 Firmware, Epyc 7003 and 85 more | 2022-05-12 | 4.9 MEDIUM | 5.5 MEDIUM |
| 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. | |||||
| CVE-2021-26337 | 1 Amd | 90 Epyc 7002, Epyc 7002 Firmware, Epyc 7003 and 87 more | 2022-05-12 | 2.1 LOW | 5.5 MEDIUM |
| 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. | |||||
| CVE-2020-12966 | 1 Amd | 214 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 211 more | 2022-02-09 | 2.1 LOW | 5.5 MEDIUM |
| 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). A local authenticated attacker could potentially exploit this vulnerability leading to leaking guest data by the malicious hypervisor. | |||||
| CVE-2021-26330 | 1 Amd | 116 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 113 more | 2021-11-19 | 2.1 LOW | 5.5 MEDIUM |
| AMD System Management Unit (SMU) may experience a heap-based overflow which may result in a loss of resources. | |||||
