Background

The Kernel package is a crucial component of the Linux operating system, responsible for managing the system's core functionality. It provides an interface between the hardware and software layers, allowing applications to communicate with the underlying hardware. The usb: dwc3: core module within the Kernel package handles USB functionality, including device enumeration, communication, and control. This module is vulnerable to a specific issue related to core softreset when switching modes.

Vulnerability Detail

The vulnerability in the usb: dwc3: core module arises when switching modes. It fails to perform a core softreset, which can lead to various security risks. Although the exact impact and attack plausibility have not been proven, this vulnerability has the potential to compromise the integrity and confidentiality of the system. It is important to note that this vulnerability has been fixed in Linux Kernel version v5.11.20 by commit 800f58217626c8b147aa40660e572ed8a0d56e3b. However, it was introduced in version v4.12 by commit 41ce1456e1dbbc7355d0fcc10cf7c337c13def24.

How To Fix

No fixed version is published for this vulnerability.

To fix this vulnerability, it is recommended to update the Kernel package to version v5.11.20 or later. This can be done by following the official update process provided by the Linux Kernel development team. By applying the necessary updates, the core softreset issue when switching modes will be resolved.
