Background

The USB xhci-plat is a component of the Linux Kernel that provides support for USB host controllers. It allows communication between the host system and USB devices. The xhci-plat driver is responsible for managing the USB controller on a platform. This vulnerability affects the xhci-plat driver when remote wake is enabled and the system is suspended.

Vulnerability Detail

The vulnerability occurs when the system is suspended while remote wake is enabled. This can lead to a crash in the xhci-plat driver, resulting in a denial of service (DoS) condition. An attacker with physical access to the system could exploit this vulnerability to cause a system crash, potentially disrupting normal operation. The vulnerability has been fixed in Linux Kernel version v5.16.5.
