Ryzen 3 3200U Firmware Security Vulnerabilities - 2023
Failure to validate the integer operand in ASP (AMD Secure Processor) bootloader may allow an attacker to introduce an integer overflow in the L2 directory table in SPI flash resulting in a potential denial of service.

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.

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.

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.
