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 ensure the proper functioning of the system. One of the components within the Kernel is the ASoC (Audio System on Chip) subsystem, which handles audio-related operations. ASoC allows for the integration of audio functionality into embedded systems, providing support for various audio codecs, digital audio interfaces, and audio processing capabilities. However, a vulnerability has been identified in the ASoC ops (operations) code, specifically in the snd_soc_put_volsw_sx() function.
Vulnerability Detail
The vulnerability in snd_soc_put_volsw_sx() allows for the acceptance of out-of-bounds values, which can lead to potential security issues. This vulnerability could be exploited by an attacker to manipulate audio volume settings beyond the intended range, potentially causing audio distortion or even system instability. The vulnerability has been addressed in the Linux Kernel version v5.4.178 by commit c33402b056de61104b6146dedbe138ca8d7ec62b.
