Vulnerabilities > AMD > Epyc 7763 Firmware
| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-08-08 | CVE-2023-20569 | Information Exposure Through Discrepancy vulnerability in multiple products A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. | 4.7 |
| 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-2021-26354 | Classic Buffer Overflow vulnerability in AMD products Insufficient bounds checking in ASP may allow an attacker to issue a system call from a compromised ABL which may cause arbitrary memory values to be initialized to zero, potentially leading to a loss of integrity. | 5.5 |
| 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-2021-26397 | Unspecified vulnerability in AMD products Insufficient address validation, may allow an attacker with a compromised ABL and UApp to corrupt sensitive memory locations potentially resulting in a loss of integrity or availability. | 7.1 |
| 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 |
