Background
The gpio: sim package is a component of the Linux Kernel, which is responsible for managing the General Purpose Input/Output (GPIO) pins on a system. GPIO pins allow the system to interact with external devices, such as sensors, buttons, and LEDs. The gpio: sim package provides a simulation environment for testing GPIO functionality. It is used by developers to emulate GPIO behavior without the need for physical hardware. However, a vulnerability has been discovered in this package that can lead to a memory leak.
Vulnerability Detail
The vulnerability in the gpio: sim package is caused by a memory leak. A memory leak occurs when a program fails to release memory that it no longer needs, resulting in a gradual depletion of available memory resources. In the case of the gpio: sim package, this memory leak can lead to resource exhaustion, causing the system to become unresponsive or crash. An attacker could potentially exploit this vulnerability to launch denial-of-service attacks or gain unauthorized access to sensitive information stored in memory. The vulnerability was introduced in version v5.17 of the Linux Kernel and has been fixed in version v6.1.13.
How To Fix
No fixed version is published for this vulnerability.
