Background

The fsl_ifc package is a memory management component in the Linux Kernel. It provides functionality for handling Input/Output (IO) mappings. IO mappings are used to establish communication between hardware devices and the operating system. The fsl_ifc package is responsible for managing these mappings and ensuring proper memory allocation and deallocation. However, a vulnerability has been discovered in the package that can lead to a memory leak in certain scenarios.

Vulnerability Detail

The vulnerability in the fsl_ifc package occurs when a probe failure happens during initialization. In such cases, the IO mapping is not properly released, resulting in a memory leak. This can lead to a gradual depletion of available memory resources, potentially causing system instability or denial of service. The vulnerability was introduced in version v3.3 of the Linux Kernel and is fixed in version v4.4.276.

How To Fix
