Ryzen 5 2400Ge Firmware Security Vulnerabilities

CVE-2020-12930

Improper parameters handling in AMD Secure Processor (ASP) drivers may allow a privileged attacker to elevate their privileges potentially leading to loss of integrity.

CVE-2020-12931

Improper parameters handling in the AMD Secure Processor (ASP) kernel may allow a privileged attacker to elevate their privileges potentially leading to loss of integrity.

CVE-2021-26316

Failure to validate the communication buffer and communication service in the BIOS may allow an attacker to tamper with the buffer resulting in potential SMM (System Management Mode) arbitrary code execution.

CVE-2021-26354

Insufficient bounds checking in ASP may allow anattacker to issue a system call from a compromised ABL which may causearbitrary memory values to be initialized to zero, potentially leading to aloss of integrity.

CVE-2021-26365

Certain size values in firmware binary headerscould trigger out of bounds reads during signature validation, leading todenial of service or potentially limited leakage of information aboutout-of-bounds memory contents.

CVE-2021-26371

A compromised or malicious ABL or UApp couldsend a SHA256 system call to the bootloader, which may result in exposure ofASP memory to userspace, potentially leading to information disclosure.

CVE-2021-26392

Insufficient verification of missing size check in 'LoadModule' may lead to an out-of-bounds write potentially allowing an attacker with privileges to gain code execution of the OS/kernel by loading a malicious TA.

CVE-2021-26393

Insufficient memory cleanup in the AMD Secure Processor (ASP) Trusted Execution Environment (TEE) may allow an authenticated attacker with privileges to generate a valid signed TA and potentially poison the contents of the process memory with attacker controlled data resulting in a loss of confiden...
