Background
The Kernel is a critical component of the Linux operating system that provides core functionality and interfaces with hardware devices. It manages system resources, including memory, processes, and input/output operations. The vulnerability identified in the Kernel's drm/amd/display module affects the DMUB (Display Microcontroller Unit Block) hardware initialization process. DMUB is responsible for managing display-related operations on AMD graphics cards.
Vulnerability Detail
The vulnerability in DMUB hw_init could lead to a potential memory leak. When the DMUB hardware is initialized, there is a possibility of memory not being properly deallocated, resulting in a memory leak. This can lead to a gradual depletion of available memory resources, potentially impacting system stability and performance. The vulnerability has been addressed in the Linux Kernel version v5.12.12 by commit aa000f828e60ac15d6340f606ec4a673966f5b0b.
