| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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-2021-26379 | Unspecified vulnerability in AMD products Insufficient input validation of mailbox data in the SMU may allow an attacker to coerce the SMU to corrupt SMRAM, potentially leading to a loss of integrity and privilege escalation. | 9.8 |
| 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 |
| 2023-05-09 | CVE-2021-46762 | Improper Input Validation vulnerability in AMD products 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. | 9.1 |
| 2023-05-09 | CVE-2021-46763 | Out-of-bounds Write vulnerability in AMD products Insufficient input validation in the SMU may enable a privileged attacker to write beyond the intended bounds of a shared memory buffer potentially leading to a loss of integrity. | 7.5 |
| 2023-05-09 | CVE-2021-46764 | Out-of-bounds Write vulnerability in AMD products Improper validation of DRAM addresses in SMU may allow an attacker to overwrite sensitive memory locations within the ASP potentially resulting in a denial of service. | 7.5 |
| 2023-05-09 | CVE-2021-46769 | Improper Input Validation vulnerability in AMD products Insufficient syscall input validation in the ASP Bootloader may allow a privileged attacker to execute arbitrary DMA copies, which can lead to code execution. | 8.8 |
| 2023-05-09 | CVE-2021-46775 | Improper Input Validation vulnerability in AMD products Improper input validation in ABL may enable an attacker with physical access, to perform arbitrary memory overwrites, potentially leading to a loss of integrity and code execution. | 6.8 |
| 2023-05-09 | CVE-2023-20520 | Out-of-bounds Write vulnerability in AMD products 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. | 9.8 |
