Background
The Kernel is a fundamental component of the Linux operating system that manages system resources and provides an interface for software to interact with the hardware. It is responsible for tasks such as memory management, process scheduling, and device drivers. The uss720_probe function is a part of the Kernel's misc/uss720 module, which handles the initialization and probing of the USS720 USB device. This vulnerability in uss720_probe leads to a memory leak, where allocated memory is not properly freed, causing a gradual depletion of available memory resources.
Vulnerability Detail
The vulnerability in uss720_probe arises due to a failure to release allocated memory in certain scenarios. This can result in a gradual accumulation of memory leaks, leading to reduced system performance and potential denial of service if the system runs out of available memory. The vulnerability was introduced in version v2.6.14 of the Linux Kernel and is fixed in version v4.9.271. The impact and attack plausibility of this vulnerability have not been proven.
How To Fix
