Background
The Kernel is a critical component of the Linux operating system that manages the communication between hardware and software. It provides essential services and functions for the proper functioning of the system. The elo_probe function in the Kernel is responsible for handling input from Elo touchscreens. Elo touchscreens are widely used in various applications, including point-of-sale systems, kiosks, and industrial control systems.
Vulnerability Detail
The elo_probe function in the Kernel has a memory leak vulnerability. This vulnerability allows an attacker to continuously allocate memory without freeing it, leading to memory exhaustion and potential system instability. An attacker could exploit this vulnerability by sending specially crafted input to the elo_probe function, causing it to leak memory. The impact of this vulnerability could range from degraded system performance to a complete system crash, depending on the severity of the memory exhaustion.
