Background

The drivers: staging: rtl8192u package is a component of the Linux Kernel, which is responsible for managing the Realtek RTL8192U Wireless LAN USB driver. This driver enables wireless network connectivity for devices using the RTL8192U chipset. The package is part of the staging area in the Linux Kernel, indicating that it is still under development and may contain experimental or incomplete code. Unfortunately, a deadlock vulnerability has been discovered in the ieee80211_beacons_stop() function of this package.

Vulnerability Detail

The vulnerability in drivers: staging: rtl8192u arises from a deadlock situation that can occur in the ieee80211_beacons_stop() function. This function is responsible for stopping the transmission of beacon frames in the wireless network. Due to a flaw in the code, a deadlock can occur when multiple threads attempt to stop the beacon transmission simultaneously. This deadlock can result in a system freeze or unresponsiveness, impacting the overall stability and functionality of the affected device. The vulnerability has been assigned the ID GSD-2022-1002547 and has been fixed in Linux Kernel version v5.18.4 by commit b34cb54923a6e5ddefbaf358c85c922c6ab456e2.
