Background

The xhci package is a component of the Linux Kernel that provides support for USB 3.0 and later versions. It includes a host controller driver that manages USB devices connected to the system. The command ring is a data structure used by the xhci driver to queue and process commands sent to USB devices. However, a vulnerability has been discovered in the xhci driver that can lead to command ring pointer corruption while aborting a command.

Vulnerability Detail

The command ring pointer corruption vulnerability in the xhci driver occurs when aborting a command. This can result in the corruption of the command ring pointer, leading to potential issues such as command misinterpretation or execution of unintended commands. The impact and attack plausibility of this vulnerability have not been proven yet. It is important to note that this vulnerability has been fixed in Linux Kernel version v5.14.14 by commit e54abefe703ab7c4e5983e889babd1447738ca42.
