Background

The interconnect: qcom: bcm-voter is a component in the Linux Kernel that manages the interconnects between different subsystems on Qualcomm-based devices. It is responsible for ensuring efficient communication and resource allocation between these subsystems. The vulnerability arises from a missing of_node_put() function call, which can lead to resource leaks and potential memory corruption.

Vulnerability Detail

The missing of_node_put() function call in the interconnect: qcom: bcm-voter component can result in resource leaks and memory corruption. This vulnerability can be exploited by an attacker to cause a denial-of-service (DoS) condition or potentially execute arbitrary code with kernel privileges. The issue was introduced in Linux Kernel version v5.7 and is fixed in version v5.12.9.

How To Fix

No fixed version is published for this vulnerability.

To fix this vulnerability, it is recommended to update the Linux Kernel to version v5.12.9 or later. This can be done by fetching the latest kernel source code from the official Linux Kernel repository (https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/) and compiling it for the target system. Alternatively, users can wait for their Linux distribution to provide an updated kernel package.
