| CVE | Severidad | EPSS | Explotación activa | Publicada | Descripción |
|---|---|---|---|---|---|
| CVE-2023-20591 | Crítica (10) | 0.30% | — | 13 ago 2024 | Improper re-initialization of IOMMU during the DRTM event may permit an untrusted platform configuration to persist, allowing an attacker to read or modify hypervisor memory, potentially resulting in loss of… |
| CVE-2023-20584 | Media (6) | 0.19% | — | 13 ago 2024 | IOMMU improperly handles certain special address ranges with invalid device table entries (DTEs), which may allow an attacker with privileges and a compromised Hypervisor to induce DTE faults to bypass RMP checks in… |
| CVE-2023-20578 | Media (6.4) | 0.12% | — | 13 ago 2024 | A TOCTOU (Time-Of-Check-Time-Of-Use) in SMM may allow an attacker with ring0 privileges and access to the BIOS menu or UEFI shell to modify the communications buffer potentially resulting in arbitrary code execution. |
| CVE-2024-21980 | Alta (7.9) | 0.45% | — | 5 ago 2024 | Improper restriction of write operations in SNP firmware could allow a malicious hypervisor to potentially overwrite a guest's memory or UMC seed resulting in loss of confidentiality and integrity. |
| CVE-2024-21978 | Alta (7.9) | 0.49% | — | 5 ago 2024 | Improper input validation in SEV-SNP could allow a malicious hypervisor to read or overwrite guest memory potentially leading to data leakage or data corruption. |
| CVE-2023-31355 | Media (6) | 0.44% | — | 5 ago 2024 | Improper restriction of write operations in SNP firmware could allow a malicious hypervisor to overwrite a guest's UMC seed potentially allowing reading of memory from a decommissioned guest. |
| CVE-2023-31347 | Media (4.9) | 0.46% | — | 13 feb 2024 | Due to a code bug in Secure_TSC, SEV firmware may allow an attacker with high privileges to cause a guest to observe an incorrect TSC when Secure TSC is enabled potentially resulting in a loss of guest integrity. |
| CVE-2023-31346 | Media (6) | 0.31% | — | 13 feb 2024 | Failure to initialize memory in SEV Firmware may allow a privileged attacker to access stale data from other guests. |
| CVE-2023-20573 | Baja (3.2) | 0.29% | — | 11 ene 2024 | A privileged attacker can prevent delivery of debug exceptions to SEV-SNP guests potentially resulting in guests not receiving expected debug information. |
| CVE-2023-20566 | Alta (7.5) | 0.37% | — | 14 nov 2023 | Improper address validation in ASP with SNP enabled may potentially allow an attacker to compromise guest memory integrity. |
| CVE-2022-23830 | Media (5.3) | 0.35% | — | 14 nov 2023 | SMM configuration may not be immutable, as intended, when SNP is enabled resulting in a potential limited loss of guest memory integrity. |
| CVE-2021-46774 | Alta (7.5) | 0.51% | — | 14 nov 2023 | Insufficient DRAM address validation in System Management Unit (SMU) may allow an attacker to read/write from/to an invalid DRAM address, potentially resulting in denial-of-service. |
| CVE-2021-46766 | Media (5.5) | 0.23% | — | 14 nov 2023 | Improper clearing of sensitive data in the ASP Bootloader may expose secret keys to a privileged attacker accessing ASP SRAM, potentially leading to a loss of confidentiality. |
