## Overview

A flaw was found in the Linux kernel's Wi-Fi driver for mt7915 chipsets. This vulnerability allows a malicious or malfunctioning Wi-Fi device to provide an invalid memory address. This can cause the driver to write data beyond its allocated memory, leading to an out-of-bounds write. Such memory corruption could potentially compromise system stability or allow for unauthorized code execution.
