Background
The Kernel is a critical component of the Linux operating system that acts as a bridge between the hardware and software layers. It provides essential functionalities and services to the system, including device drivers, memory management, and process scheduling. The arm_scmi module within the Kernel is responsible for handling communication with the System Control and Management Interface (SCMI) on ARM-based systems. SCMI is a standard interface for managing system resources and power states on ARM platforms. Unfortunately, a vulnerability has been discovered in the arm_scmi module that affects the list protocols enumeration in the base protocol.
Vulnerability Detail
The vulnerability in the arm_scmi module allows an attacker to exploit the list protocols enumeration in the base protocol. By leveraging this vulnerability, an attacker may be able to gain unauthorized access to sensitive information or execute arbitrary code on the affected system. The vulnerability was introduced in version v4.17 of the Linux Kernel and has been fixed in version v5.17.14. The impact and attack plausibility of this vulnerability have not been proven yet.
