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 to enable the proper functioning of the system. ASoC (Audio System on Chip) is a subsystem within the Kernel that handles audio-related functionalities. The mediatek driver in ASoC is responsible for supporting MediaTek audio devices. One of the drivers, mt8173_max98090_dev_probe, is vulnerable to an error handling issue.
Vulnerability Detail
The vulnerability in mt8173_max98090_dev_probe driver arises from improper error handling. When the driver encounters an error during the probe process, it fails to handle it correctly, leading to potential issues. An attacker could exploit this vulnerability to cause a denial-of-service (DoS) condition or potentially execute arbitrary code with elevated privileges. The vulnerability was introduced in Linux Kernel version v4.2 and has been fixed in version v5.10.121.
