Amd Ryzen 7 5700U Firmware vulnerabilities

CVE-2021-46758 [MEDIUM] CVE-2021-46758: Insufficient validation of SPI flash addresses in the ASP (AMD Secure Processor) bootloader may allo Insufficient validation of SPI flash addresses in the ASP (AMD Secure Processor) bootloader may allow an attacker to read data in memory mapped beyond SPI flash resulting in a potential loss of availability and integrity.

CVE-2023-20555 [HIGH] CWE-787 CVE-2023-20555: Insufficient input validation in CpmDisplayFeatureSmm may allow an attacker to corrupt SMM memory by Insufficient input validation in CpmDisplayFeatureSmm may allow an attacker to corrupt SMM memory by overwriting an arbitrary bit in an attacker-controlled pointer potentially leading to arbitrary code execution in SMM.

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-2021-26365 [HIGH] CWE-125 CVE-2021-26365: Certain size values in firmware binary headers could trigger out of bounds reads during signature va Certain size values in firmware binary headers could trigger out of bounds reads during signature validation, leading to denial of service or potentially limited leakage of information about out-of-bounds memory contents.

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-2021-26388 [MEDIUM] CWE-125 CVE-2021-26388: Improper validation of the BIOS directory may allow for searches to read beyond the directory table Improper validation of the BIOS directory may allow for searches to read beyond the directory table copy in RAM, exposing out of bounds memory contents, resulting in a potential denial of service.
