Background
The ASoC (Audio System on Chip) framework in the Linux Kernel is responsible for managing audio devices on embedded systems. One of the supported audio codecs is the rt5645. This codec is commonly used in various devices, including smartphones, tablets, and laptops. The rt5645 codec provides features such as audio playback, recording, and audio signal processing. However, a vulnerability has been identified in the rt5645 driver that can lead to erroneous cleanup order, potentially resulting in security issues.
Vulnerability Detail
The vulnerability in the ASoC rt5645 driver arises from an incorrect cleanup order. When certain conditions are met, the driver may perform cleanup operations in an incorrect order, leading to potential security vulnerabilities. Although the exact impact and attack plausibility have not been proven, this vulnerability should be taken seriously as it could potentially allow an attacker to execute arbitrary code or cause a denial-of-service (DoS) condition. The vulnerability has been fixed in the Linux Kernel version v5.4.198 by commit abe7554da62cb489712a54de69ef5665c250e564.
