Background
The Linux Kernel is the core component of the Linux operating system, responsible for managing system resources and providing an interface for software applications. The drivers: usb: host module within the Linux Kernel handles USB host functionality, allowing the system to communicate with USB devices. This module is crucial for USB device support on Linux systems.
Vulnerability Detail
The vulnerability identified as GSD-2022-1004031 in the drivers: usb: host module of the Linux Kernel involves a deadlock issue in the oxu_bus_suspend() function. A deadlock occurs when two or more processes or threads are unable to proceed because each is waiting for the other to release a resource. In this case, the deadlock can be triggered during the suspension of the USB bus, potentially leading to system instability or unresponsiveness. The impact and attack plausibility of this vulnerability have not been proven yet.
