Background

The Kernel package is a critical component of the Linux operating system. It provides the core functionality and interfaces for the system's hardware, software, and processes. The USB DWC3 Core is a subsystem within the Kernel responsible for managing USB functionality. It enables communication between USB devices and the operating system. However, a vulnerability has been discovered in the USB DWC3 Core that can lead to a kernel panic when rebooting the system.

Vulnerability Detail

The vulnerability in the USB DWC3 Core arises from a flaw in the code that handles the reboot process. When a reboot is initiated, the flawed code can trigger a kernel panic, causing the system to crash. This vulnerability can be exploited by an attacker with local access to the system, potentially leading to a denial-of-service (DoS) scenario. The vulnerability was introduced in version v5.4.128 of the Linux Kernel and has been fixed in version v5.4.128 by commit fd7c4bd582494934be15d41aebe0dbe23790605f.

How To Fix

No fixed version is published for this vulnerability.

To fix this vulnerability, it is recommended to update the Linux Kernel to version v5.4.128 or later. This can be done by obtaining the updated Kernel source code from the official repository (https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/) and compiling it for the target system. Alternatively, users can wait for their Linux distribution to provide an updated package containing the fixed Kernel version.
