Background
The fsl_ifc package is a memory management component 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 on Freescale/NXP PowerPC platforms. The fsl_ifc package is an integral part of the Linux Kernel and is widely used in systems running on PowerPC architectures.
Vulnerability Detail
The vulnerability identified in the fsl_ifc package is related to a memory leak issue that occurs when the probe of the driver fails. The private memory allocated by the driver is not properly released, leading to a memory leak. This vulnerability can potentially exhaust system memory resources over time, resulting in performance degradation or system instability. The vulnerability was introduced in version v3.3 of the Linux Kernel and has been fixed in version v5.13.4.
