|---|---|---|---|---|---|---|---|---|
| CVE-2021-46762 | Low | 0.25 | 3.9 | 0.00 | May 9, 2023 | Insufficient input validation in the SMU may allow an attacker to corrupt SMU SRAM potentially leading to a loss of integrity or denial of service. | ||
| CVE-2023-20573 | Low | 0.21 | 3.2 | 0.00 | Jan 11, 2024 | A privileged attacker can prevent delivery of debug exceptions to SEV-SNP guests potentially resulting in guests not receiving expected debug information. | ||
| 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-2023-20528 | Low | 0.16 | 2.4 | 0.00 | Jan 11, 2023 | Insufficient input validation in the SMU may allow a physical attacker to exfiltrate SMU memory contents over the I2C bus potentially leading to a loss of confidentiality. | ||
| 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. | ||
| CVE-2022-23830 | Low | 0.12 | 1.9 | 0.00 | Nov 14, 2023 | SMM configuration may not be immutable, as intended, when SNP is enabled resulting in a potential limited loss of guest memory integrity. | ||
| CVE-2021-26345 | Low | 0.12 | 1.9 | 0.00 | Nov 14, 2023 | Failure to validate the value in APCB may allow a privileged attacker to tamper with the APCB token to force an out-of-bounds memory read potentially resulting in a denial of service. |
