Background

The Kernel package is a crucial component of the Linux operating system. It provides the core functionality and interfaces for the system, including device drivers, process management, and memory management. The rtl8712 module within the staging directory of the Kernel package is responsible for supporting Realtek RTL8712U Wireless LAN 802.11n USB 2.0 Network Adapter. This vulnerability specifically affects the usb_read8() function and related functions within the rtl8712 module.

Vulnerability Detail
