Background
The drm/amd/display package is a component of the Linux Kernel that handles display functionality for AMD graphics cards. It provides the necessary drivers and interfaces for managing display output and rendering on these devices. The package is an integral part of the Linux operating system and is widely used in systems with AMD graphics hardware.
Vulnerability Detail
The vulnerability identified in the drm/amd/display package involves a lack of validation for a modulo operation before performing a division. This can lead to a division by zero error, which may result in a system crash or other unexpected behavior. An attacker could potentially exploit this vulnerability to cause a denial-of-service (DoS) condition or execute arbitrary code with elevated privileges. The vulnerability has been assigned the ID GSD-2022-1002888 and has been fixed in Linux Kernel version v5.17.15 by commit 96725758eff7b3805e4e94d1443a100757412720.
