Background
The Kernel is a crucial component of the Linux operating system that acts as a bridge between the hardware and software layers. It provides essential functionalities and services to enable the proper functioning of the system. The media subsystem within the Kernel handles various media-related operations, including USB devices. One of the USB drivers in the Kernel, go7007, is responsible for supporting the s2250-board. However, a vulnerability has been identified in the probe() function of this driver, leading to a memory leak.
Vulnerability Detail
The vulnerability in the media: usb: go7007: s2250-board driver's probe() function allows for a memory leak. When the driver is probed, it fails to release allocated memory in certain scenarios, resulting in a memory leak. This can potentially exhaust system resources and lead to performance degradation or even system instability. The vulnerability was introduced in version v3.10 of the Linux Kernel and has been fixed in version v5.17.2.
