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 essential for efficient data transfer between the processor and peripherals. The fsl_ifc package is commonly used in systems based on Freescale/NXP processors. However, a vulnerability has been discovered in the package that can lead to a memory leak when the probe fails.
Vulnerability Detail
The vulnerability in the fsl_ifc package occurs when the probe process fails. In such cases, the IO mapping is not properly released, resulting in a memory leak. This can lead to resource exhaustion and potential system instability. The vulnerability was introduced in version v3.3 of the Linux Kernel and has been fixed in version v5.4.134 by commit d9213d4f372d30b5bc4d921795d6bed0c0e3eebf.
