Background

linux-libc-dev is a package in the Linux kernel that provides the C library for user-space programs. It contains the necessary header files and libraries for compiling and linking programs that use the standard C library. The package is widely used in Linux distributions and is essential for the proper functioning of various software applications. However, a vulnerability has been discovered in the USB Type-C DisplayPort driver of linux-libc-dev.

Vulnerability Detail

The vulnerability in the USB Type-C DisplayPort driver of linux-libc-dev allows for the creation of sysfs nodes before the completion of typec_altmode_set_drvdata(). This can lead to a NULL pointer error when accessing certain sysfs nodes, such as dp->hpd or dp->lock, resulting in a denial of service (DoS) condition. An attacker can exploit this vulnerability by triggering a sysfs read operation, causing the driver to crash or become unresponsive.
