AMD Advanced Micro Devices (AMD) RADEON RX VEGA 56 Firmware

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.

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

Insufficient verification of multiple header signatures while loading a Trusted Application (TA) may allow an attacker with privileges to gain code execution in that TA or the OS/kernel.

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.

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 confidentiality.

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.
