Background
The Kernel is a critical component of the Linux operating system that manages communication between hardware and software. It provides essential functionalities and drivers for various hardware devices. The gpiolib subsystem within the Kernel handles interactions with General Purpose Input/Output (GPIO) pins. ACPI (Advanced Configuration and Power Interface) is a standard for configuring hardware and managing power on modern systems. This vulnerability specifically affects the ACPI implementation in the gpiolib subsystem.
Vulnerability Detail
The vulnerability in gpiolib: acpi arises from the incorrect usage of format characters in certain code sections. This can lead to potential security vulnerabilities, although the actual impact and attack plausibility have not been proven yet. The vulnerability was introduced in version v4.14 of the Linux Kernel and has been fixed in version v5.17.4. Exploiting this vulnerability could potentially allow an attacker to execute arbitrary code or cause a denial-of-service (DoS) condition.
How To Fix
No fixed version is published for this vulnerability.
