Background

The fsl_ifc package is a memory management module in the Linux Kernel. It is responsible for handling memory allocation and deallocation for the Freescale Integrated Flash Controller (IFC) driver. The IFC driver is used for accessing flash memory devices on Freescale/NXP PowerPC-based systems. The fsl_ifc package provides an interface for managing private memory used by the IFC driver.

Vulnerability Detail

The vulnerability identified in the fsl_ifc package is a memory leak issue that occurs when the probe of the fsl_ifc driver fails. During the probe process, if an error occurs, the driver fails to release the private memory allocated, leading to a memory leak. This vulnerability can result in a gradual depletion of system memory resources, potentially causing system instability or denial of service conditions.

How To Fix

No fixed version is published for this vulnerability.

To fix this vulnerability, it is recommended to update the Linux Kernel to version v4.14.240 or later. The fix for this issue was implemented in commit 7626ffbea708e5aba6912295c012d2b409a1769f. Updating the kernel will ensure that the memory leak is properly addressed and the private memory is released in case of a probe failure.
