Background
The Kernel package is a critical component of the Linux operating system. It provides the core functionality and interfaces for various hardware devices and software components. The staging subsystem in the Kernel is used for drivers that are not yet considered stable. The rtl8723bs driver is part of the staging subsystem and is responsible for managing the Realtek RTL8723BS wireless chipset. This vulnerability affects the rtl8723bs driver when disconnecting from a wireless network.
Vulnerability Detail
The vulnerability in the rtl8723bs driver can lead to a possible deadlock when disconnecting from a wireless network. A deadlock occurs when two or more processes are unable to proceed because each is waiting for the other to release a resource. In this case, the deadlock can occur during the disconnect process, potentially causing the system to become unresponsive or crash. The exact impact and attack plausibility of this vulnerability have not been proven. It is important to note that this vulnerability has been fixed in Linux Kernel version v5.15.5 by commit 353a6e9acb45a66f8fb80b07c2f4097cf4b826d1.
