| CVE | Vendor / Product | Sev | Risk | CVSS | EPSS | KEV | Published | Description |
|---|---|---|---|---|---|---|---|---|
| CVE-2021-26340 | Hig | 0.55 | 8.4 | 0.00 | Dec 10, 2021 | 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). | ||
| CVE-2023-20575 | Med | 0.42 | 6.5 | 0.01 | Jul 11, 2023 | A potential power side-channel vulnerability in some AMD processors may allow an authenticated attacker to use the power reporting functionality to monitor a program’s execution inside an AMD SEV VM potentially resulting in a leak of sensitive information. | ||
| 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-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-2022-27672 | Med | 0.31 | 4.7 | 0.00 | Mar 1, 2023 | When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the sibling thread after an SMT mode switch potentially resulting in information disclosure. |
