Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM potentially leading to arbitrary code execution.

Failure to validate the AMD SMM communication buffer may allow an attacker to corrupt the SMRAM potentially leading to arbitrary code execution.

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.

Improper input validation in the AMD RadeonTM Graphics display driver may allow an attacker to corrupt the display potentially resulting in denial of service.

Improper signature verification of RadeonTM RX Vega M Graphics driver for Windows may allow an attacker with admin privileges to launch AMDSoftwareInstaller.exe without validating the file signature potentially leading to arbitrary code execution.

Improper signature verification of RadeonTM RX Vega M Graphics driver for Windows may allow an attacker with admin privileges to launch RadeonInstaller.exe without validating the file signature potentially leading to arbitrary code execution.

GPU kernel implementations susceptible to memory leak

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.

Insufficient bounds checking in the ASP (AMD Secure Processor) may allow an attacker to access memory outside the bounds of what is permissible to a TA (Trusted Application) resulting in a potential denial of service.
