Background
The iio: accel: kxcjk-1013 package is a component of the Linux Kernel. It provides support for the KXCJK-1013 accelerometer sensor. The accelerometer is used to measure acceleration forces and is commonly found in devices such as smartphones and tablets. The package allows applications to interact with the sensor and retrieve acceleration data. However, a vulnerability has been discovered in the package that could lead to a memory leak.
Vulnerability Detail
The vulnerability in iio: accel: kxcjk-1013 is related to a possible memory leak in the probe and remove functions. When the package is initialized or removed, there is a chance that memory resources are not properly released, resulting in a memory leak. This can lead to a gradual depletion of available memory, potentially causing system instability or denial of service. The vulnerability was introduced in version v4.2 of the Linux Kernel and has been fixed in version v4.19.221.
