|---|---|---|---|---|---|---|---|---|
| CVE-2021-46744 | Med | 0.42 | 6.5 | 0.00 | May 11, 2022 | 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-2021-26341 | Med | 0.42 | 6.5 | 0.00 | Mar 11, 2022 | Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage. | ||
| CVE-2023-20588 | Med | 0.37 | 5.5 | 0.12 | Aug 8, 2023 | A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality. | ||
| CVE-2021-26371 | Med | 0.36 | 5.5 | 0.00 | May 9, 2023 | A compromised or malicious ABL or UApp could send a SHA256 system call to the bootloader, which may result in exposure of ASP memory to userspace, potentially leading to information disclosure. | ||
| CVE-2022-23824 | Med | 0.36 | 5.5 | 0.01 | Nov 9, 2022 | IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure. | ||
| CVE-2021-46778 | Med | 0.36 | 5.6 | 0.00 | Aug 10, 2022 | Execution unit scheduler contention may lead to a side channel vulnerability found on AMD CPU microarchitectures codenamed “Zen 1”, “Zen 2” and “Zen 3” that use simultaneous multithreading (SMT). By measuring the contention level on scheduler queues an attacker may… | ||
| CVE-2021-26401 | Med | 0.36 | 5.6 | 0.00 | Mar 11, 2022 | LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs. | ||
| CVE-2020-12966 | Med | 0.36 | 5.5 | 0.00 | Feb 4, 2022 | 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… | ||
| CVE-2021-26330 | Med | 0.36 | 5.5 | 0.00 | Nov 16, 2021 | AMD System Management Unit (SMU) may experience a heap-based overflow which may result in a loss of resources. | ||
| CVE-2020-12954 | Med | 0.36 | 5.5 | 0.00 | Nov 16, 2021 | 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-2023-20521 | Low | 0.21 | 3.3 | 0.00 | Nov 14, 2023 | TOCTOU in the ASP Bootloader may allow an attacker with physical access to tamper with SPI ROM records after memory content verification, potentially leading to loss of confidentiality or a denial of service. | ||
| CVE-2021-26342 | Low | 0.21 | 3.3 | 0.00 | May 11, 2022 | In SEV guest VMs, the CPU may fail to flush the Translation Lookaside Buffer (TLB) following a particular sequence of operations that includes creation of a new virtual machine control block (VMCB). The failure to flush the TLB may cause the microcode to use stale TLB… | ||
| CVE-2023-20526 | Low | 0.12 | 1.9 | 0.00 | Nov 14, 2023 | Insufficient input validation in the ASP Bootloader may enable a privileged attacker with physical access to expose the contents of ASP memory potentially leading to a loss of confidentiality. |
