Background
The renesas-rpc-if is a memory management component in the Linux Kernel. It provides an interface for communication between the Renesas RPC (Remote Procedure Call) protocol and the platform devices. The RPC protocol is commonly used in embedded systems for inter-process communication. The renesas-rpc-if component is responsible for managing the memory resources used by the RPC protocol. However, a vulnerability has been discovered in this component that can lead to a memory leak in certain error scenarios.
Vulnerability Detail
The vulnerability in renesas-rpc-if occurs when an error condition is encountered during the initialization or setup of the RPC protocol. In such cases, the component fails to properly release the platform device, 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 v5.9 of the Linux Kernel and has been fixed in version v5.15.35.
How To Fix
