Background
The Kernel package is a fundamental component of the Linux operating system, responsible for managing the system's core functionality. It provides an interface between the hardware and software layers, allowing applications to communicate with the underlying hardware. The nfp_tunnel_add_shared_mac() function is a part of the Kernel's flower module, which handles network flow processing. This vulnerability in nfp_tunnel_add_shared_mac() could potentially lead to a memory leak, impacting the stability and performance of the system.
Vulnerability Detail
The vulnerability arises from a potential memory leak in the nfp_tunnel_add_shared_mac() function of the Kernel's flower module. When this function is called, there is a possibility that memory resources are not properly released, resulting in a memory leak. This can lead to a gradual depletion of available memory, potentially causing system instability and performance degradation. The impact and attack plausibility of this vulnerability have not been proven yet.
