Background
The Kernel package is a fundamental component of the Linux operating system, responsible for managing the system's resources and facilitating communication between hardware and software. It provides essential functionalities for device drivers, memory management, process scheduling, and more. The drm/msm/dp module within the Kernel package specifically handles display-related operations for Qualcomm Snapdragon chipsets. This vulnerability affects the dp_panel struct within the module, which is responsible for populating the connector information for display panels.
Vulnerability Detail
The vulnerability arises from a missing connector population in the dp_panel struct of the drm/msm/dp module. This oversight can lead to various security risks and potential exploits. Attackers may leverage this vulnerability to manipulate or compromise the display functionality, potentially leading to unauthorized access, information disclosure, or system instability. The vulnerability was introduced in version v5.10.67 of the Linux Kernel and has been fixed in version v5.10.110.
