| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-08-13 | CVE-2023-20578 | Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products 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. | 6.4 |
| 2023-11-14 | CVE-2021-26345 | Out-of-bounds Read vulnerability in AMD products 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. | 4.9 |
| 2023-11-14 | CVE-2021-46774 | Unspecified vulnerability in AMD products 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. | 7.5 |
| 2023-11-14 | CVE-2023-20521 | Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products 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. | 5.7 |
| 2023-11-14 | CVE-2023-20526 | Unspecified vulnerability in AMD products 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. low complexity amd | 4.6 |
| 2023-11-14 | CVE-2023-20533 | Unspecified vulnerability in AMD products 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. | 7.5 |
| 2023-11-14 | CVE-2023-20592 | Unspecified vulnerability in AMD products 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. | 6.5 |
| 2023-07-24 | CVE-2023-20593 | An issue in “Zen 2” CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive information. | 5.5 |
| 2023-07-11 | CVE-2023-20575 | Information Exposure Through Discrepancy vulnerability in AMD products 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. | 6.5 |
| 2023-05-09 | CVE-2021-46756 | Improper Input Validation vulnerability in AMD products Insufficient validation of inputs in SVC_MAP_USER_STACK in the ASP (AMD Secure Processor) bootloader may allow an attacker with a malicious Uapp or ABL to send malformed or invalid syscall to the bootloader resulting in a potential denial of service and loss of integrity. | 9.1 |
