Related : CVE
Date | Alert | Description | |
---|---|---|---|
10 | 2024-08-13 | CVE-2023-20591 | 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 confidentiality, integrity, and availability. |
6 | 2024-08-13 | CVE-2023-20584 | 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 SEV-SNP, potentially leading to a loss of guest integrity. |
6.4 | 2024-08-13 | CVE-2023-20578 | 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. |
8.2 | 2024-08-13 | CVE-2021-26344 | An out of bounds memory write when processing the AMD PSP1 Configuration Block (APCB) could allow an attacker with access the ability to modify the BIOS image, and the ability to sign the resulting image, to potentially modify the APCB block resulting in arbitrary code execution. |
7.9 | 2024-08-05 | CVE-2024-21980 | 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. |
7.9 | 2024-08-05 | CVE-2024-21978 | 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. |
6 | 2024-08-05 | CVE-2023-31355 | 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. |
4.9 | 2024-02-13 | CVE-2023-31347 | 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. Â |
6 | 2024-02-13 | CVE-2023-31346 | Failure to initialize memory in SEV Firmware may allow a privileged attacker to access stale data from other guests. |
3.2 | 2024-01-11 | CVE-2023-20573 | A privileged attacker can prevent delivery of debug exceptions to SEV-SNP guests potentially resulting in guests not receiving expected debug information. |
6.5 | 2023-11-14 | CVE-2023-20592 | Improper or unexpected behavior of the INVD instruction in some AMD CPUs may allow an attacker with a malicious hypervisor to affect cache line write-back behavior of the CPU leading to a potential loss of guest virtual machine (VM) memory integrity. |
7.5 | 2023-11-14 | CVE-2023-20566 | Improper address validation in ASP with SNP enabled may potentially allow an attacker to compromise guest memory integrity. |
7.5 | 2023-11-14 | CVE-2023-20533 | 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. |
4.6 | 2023-11-14 | CVE-2023-20526 | 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. |
5.7 | 2023-11-14 | CVE-2023-20521 | 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. |
5.3 | 2023-11-14 | CVE-2022-23830 | SMM configuration may not be immutable, as intended, when SNP is enabled resulting in a potential limited loss of guest memory integrity. |
7.5 | 2023-11-14 | CVE-2021-46774 | 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. |
4.9 | 2023-11-14 | CVE-2021-26345 | 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. |
4.4 | 2023-09-20 | CVE-2023-20594 | Improper initialization of variables in the DXE driver may allow a privileged user to leak sensitive information via local access. |
6.5 | 2023-07-11 | CVE-2023-20575 | 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. |
7.5 | 2023-05-09 | CVE-2023-20524 | An attacker with a compromised ASP could possibly send malformed commands to an ASP on another CPU, resulting in an out of bounds write, potentially leading to a loss a loss of integrity. |
9.8 | 2023-05-09 | CVE-2023-20520 | Improper access control settings in ASP Bootloader may allow an attacker to corrupt the return address causing a stack-based buffer overrun potentially leading to arbitrary code execution. |
