Background
The Kernel is a critical component of the Linux operating system that manages communication between hardware and software. It provides essential functions and services for the proper functioning of the system. ASoC (Audio System on Chip) is a subsystem within the Kernel that handles audio-related functionalities. The mt8173_max98090_dev_probe function is responsible for initializing the MediaTek MT8173 audio codec driver. However, a vulnerability has been identified in this function that could lead to potential security issues.
Vulnerability Detail
The vulnerability in mt8173_max98090_dev_probe function in the Kernel allows for improper error handling. This could result in various security risks, such as denial of service (DoS) attacks, privilege escalation, or information disclosure. An attacker could exploit this vulnerability by triggering specific error conditions, leading to unexpected behavior or system crashes. The vulnerability was introduced in Kernel version v4.2 and has been fixed in version v5.4.198 by commit 23f340ed906c758cec6527376768e3bc1474ac30.
