Background
The iio: accel: kxcjk-1013 is a driver module in the Linux Kernel that provides support for the KXCJK-1013 accelerometer. This module allows applications to access and utilize the accelerometer's data for various purposes, such as motion detection and orientation sensing. However, a vulnerability has been discovered in the module that can lead to a memory leak issue.
Vulnerability Detail
The vulnerability in the iio: accel: kxcjk-1013 module can result in a memory leak during the probe and remove operations. When the module is initialized or removed, there is a possibility of not properly releasing allocated memory, leading to a gradual depletion of available memory resources. This can eventually cause system instability, performance degradation, or even denial of service if the memory leak is severe. The vulnerability was introduced in Linux Kernel version v4.2 and has been fixed in version v4.4.295.
How To Fix
