Background
The Linux Kernel is the core component of the Linux operating system. It provides essential functionality and interfaces for hardware, software, and user applications. The Linux Kernel includes various device drivers to enable communication with different hardware components. One such driver is the USB host driver, which allows the system to interact with USB devices. However, a vulnerability has been identified in the oxu_bus_suspend() function of the USB host driver, which can lead to a deadlock situation.
Vulnerability Detail
The oxu_bus_suspend() function in the USB host driver of the Linux Kernel is susceptible to a deadlock. When certain conditions are met, the function can enter a state where it cannot proceed, resulting in a deadlock. This vulnerability can be exploited by an attacker to cause a denial-of-service (DoS) condition or potentially execute arbitrary code. The impact and attack plausibility of this vulnerability have not been proven yet.
