Background

The Kernel package is a crucial component of the Linux operating system, responsible for managing the system's core functionality. It provides an interface between the hardware and software layers, allowing applications to communicate with the underlying hardware. The bus subsystem within the Kernel package handles the configuration and management of buses on Qualcomm platforms. This vulnerability specifically affects the Qualcomm bus driver in the Kernel package.

Vulnerability Detail

The vulnerability in the bus driver of the Kernel package allows for a potential security breach. Specifically, the child node is not properly released before returning, which may lead to resource leaks or other memory-related issues. While the impact and attack plausibility have not been proven, it is essential to address this vulnerability to ensure the integrity and security of the system. The vulnerability was introduced in version v4.9 of the Linux Kernel and has been fixed in version v4.19.191.

How To Fix

No fixed version is published for this vulnerability.

To fix this vulnerability, it is recommended to update the Kernel package to version v4.19.191 or later. This update includes the necessary commit (a399dd80e697a02cfb23e2fc09b87849994043d9) that resolves the issue. Updating the Kernel package ensures that the child node is properly released before returning, mitigating the potential security risks associated with this vulnerability.
