Background
The Kernel package is a critical component of the Linux operating system, responsible for managing the system's core functionality. It includes various subsystems and drivers that enable communication between hardware and software components. One such subsystem is 'media', which provides support for multimedia devices. Within the 'media' subsystem, the 'usb' module handles USB-based multimedia devices. The 'go7007' driver is specifically designed for the Go7007 USB video capture device, and the 's2250-board' module is responsible for managing the board-specific operations for this device.
Vulnerability Detail
The vulnerability identified in the 'media: usb: go7007: s2250-board' module is a memory leak issue that occurs during the probe() function. When the driver initializes and probes the hardware, it fails to release certain allocated memory resources, leading to a memory leak. This vulnerability could potentially exhaust system memory over time, resulting in degraded performance or even system instability. It is important to note that the impact and likelihood of an attack exploiting this vulnerability have not been proven.
How To Fix
No fixed version is published for this vulnerability.

Workaround
As a temporary workaround, users can unload the 'go7007' driver module to prevent the vulnerability from being exploited. This can be done by executing the following command as root or with sudo privileges:
rmmod go7007
However, it is important to note that this workaround will disable the functionality provided by the 'go7007' driver and may impact the usability of the Go7007 USB video capture device.
Conclusion
The vulnerability in the 'media: usb: go7007: s2250-board' module of the Kernel package has been identified and addressed in the Linux Kernel version v4.19.238. Users are advised to update their Kernel version to v4.19.238 or later to mitigate the vulnerability. As a temporary workaround, the 'go7007' driver module can be unloaded, but this will disable the functionality of the Go7007 USB video capture device.
