Amd 3Rd Gen Amd Epyc Processors vulnerabilities

CVE-2023-20569 [MEDIUM] CWE-203 CVE-2023-20569: A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the retur A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure.

CVE-2023-20575 [MEDIUM] CWE-203 CVE-2023-20575: A potential power side-channel vulnerability in some AMD processors may allow an authenticated atta 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.

CVE-2021-46756 [CRITICAL] CWE-20 CVE-2021-46756: Insufficient validation of inputs in SVC_MAP_USER_STACK in the ASP (AMD Secure Processor) bootloader 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.

CVE-2021-26356 [HIGH] CWE-367 CVE-2021-26356: A TOCTOU in ASP bootloader may allow an attacker to tamper with the SPI ROM following data read to m 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.

CVE-2021-26354 [MEDIUM] CWE-120 CVE-2021-26354: Insufficient bounds checking in ASP may allow an attacker to issue a system call from a compromised 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.

CVE-2021-26371 [MEDIUM] CVE-2021-26371: A compromised or malicious ABL or UApp could send a SHA256 system call to the bootloader, which may 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.
