Linux Kernel Memory Leak Vulnerability in MTK Ethernet Driver

Vulnerability

A memory leak vulnerability has been identified in the Linux kernel's MTK Ethernet driver. The issue arises in the 'mtk_probe' function, where the 'mtk_wed_add_hw' function allocates memory that is not properly freed if an error occurs or the module is removed. This vulnerability affects the stable versions of the Linux kernel.

Impact

The vulnerability can lead to a memory leak, causing increased memory usage and potentially leading to memory exhaustion over time.
