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 direct memory access between devices and the CPU. The fsl_ifc package is commonly used in systems with Freescale (now NXP) processors. This vulnerability in the fsl_ifc package can lead to a memory leak when the probe process fails.
Vulnerability Detail
The vulnerability in the fsl_ifc package occurs when the probe process fails. In such cases, IO mappings are 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 has been fixed in version v5.13.4.
