Background
The Kernel package is a critical component of the Linux operating system. It provides core functionalities and acts as a bridge between the hardware and software layers. The package includes various drivers, including the rtl8723bs driver for Realtek wireless chips. This driver enables wireless connectivity on devices using Realtek RTL8723BS wireless chips. However, a vulnerability has been discovered in the rtl8723bs driver that can lead to a possible deadlock when disconnecting from a wireless network.
Vulnerability Detail
The vulnerability in the rtl8723bs driver can result in a deadlock situation 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 disconnection process, potentially causing the system to become unresponsive or crash. The impact of this vulnerability may vary depending on the specific system configuration and usage patterns. It is important to note that the actual attack plausibility and impact have not been proven yet.
