Background

The fsl_ifc package is a component of the Linux Kernel that provides support for the Freescale Integrated Flash Controller (IFC) found in certain embedded systems. The IFC is responsible for managing the flash memory used for storage in these systems. The fsl_ifc package includes drivers and functionality to interact with the IFC hardware. However, a vulnerability has been discovered in the package that 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 this situation, the package fails to properly release the IO mapping, resulting in a memory leak. This can lead to a gradual depletion of available memory resources, potentially causing system instability or crashes. The vulnerability was introduced in version v3.3 of the Linux Kernel and has been fixed in version v4.14.240.

How To Fix

No fixed version is published for this vulnerability.

Conclusion

The memory leak vulnerability in the fsl_ifc package can be mitigated by updating the Linux Kernel to version v4.14.240 or later. This update includes the necessary fix to properly release the IO mapping on probe failure. For further support on vulnerability remediation, please contact DevNack.com.
