| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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-2023-20592 | 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 |
| 2023-08-08 | CVE-2023-20588 | Divide By Zero vulnerability in multiple products A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality. | 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 |
| 2023-05-09 | CVE-2021-26356 | Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products A TOCTOU in ASP bootloader may allow an attacker to tamper with the SPI ROM following data read to memory potentially resulting in S3 data corruption and information disclosure. | 7.4 |
| 2023-05-09 | CVE-2021-26371 | Unspecified vulnerability in AMD products A compromised or malicious ABL or UApp could send a SHA256 system call to the bootloader, which may result in exposure of ASP memory to userspace, potentially leading to information disclosure. | 5.5 |
| 2023-05-09 | CVE-2021-26406 | Unspecified vulnerability in AMD products Insufficient validation in parsing Owner's Certificate Authority (OCA) certificates in SEV (AMD Secure Encrypted Virtualization) and SEV-ES user application can lead to a host crash potentially resulting in denial of service. | 7.5 |
