Background
The Kernel is a crucial component of the Linux operating system, responsible for managing system resources and facilitating communication between hardware and software. It provides essential functions and services to enable the proper functioning of the system. The vulnerability affects the mt76 driver module, specifically the mt7915 wireless chipset. This chipset is commonly used in Wi-Fi devices and provides wireless connectivity. The vulnerability in the txrate reporting functionality of the mt7915 driver can lead to inaccurate transmission rate reporting, potentially impacting network performance and reliability.
Vulnerability Detail
The vulnerability arises from a flaw in the txrate reporting implementation of the mt7915 driver in the Kernel. When transmitting data, the driver incorrectly reports the transmission rate, leading to inaccurate information about the actual transmission speed. This can result in suboptimal network performance and may cause issues such as slower data transfer rates or intermittent connectivity problems. The vulnerability was introduced in Kernel version v5.8 and has been fixed in version v5.12.4.
How To Fix
