Background
The Kernel package is an essential component of the Linux operating system, responsible for managing the system's core functions and providing an interface between hardware and software. It includes various subsystems, such as USB drivers, that enable communication with USB devices. One of these drivers, dwc2, is used for managing USB controllers. However, a vulnerability has been identified in the dwc2 driver that could potentially lead to security issues.
Vulnerability Detail
The vulnerability in the dwc2 driver arises from a failure to check the return value after calling the platform_get_resource() function. This oversight could allow an attacker to exploit the driver and execute arbitrary code or perform other malicious actions. 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 the Linux Kernel version v5.4.152 by commit 8b9c1c33e51d0959f2aec573dfbac0ffd3f5c0b7.
