Background
The Kernel is a crucial component of the Linux operating system, responsible for managing system resources and facilitating communication between hardware and software. It provides essential functions and services to enable the proper functioning of the system. The arm_scmi module within the Kernel is specifically designed for ARM-based systems and handles communication with the System Control and Management Interface (SCMI). This interface allows software to interact with various system components, such as power management, sensors, and performance monitoring. However, a vulnerability has been identified 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 manipulate the list protocols enumeration in the base protocol. By exploiting this vulnerability, an attacker could potentially gain unauthorized access to sensitive system information or execute arbitrary code on the affected system. The impact of this vulnerability can vary depending on the specific system configuration and the privileges of the attacker. It is important to note that this vulnerability has not been proven to be exploitable in the wild, but it is still crucial to address it to ensure the security and integrity of the system.
