Background
The Kernel package is a critical component of the Linux operating system, responsible for managing the system's core functionality. It provides an interface between the hardware and software layers, allowing applications to communicate with the underlying hardware. The ASoC (Audio System on Chip) subsystem within the Kernel package is specifically designed for audio-related functionalities. One of the components in the ASoC subsystem is the rockchip_i2s_tdm_resume module, which handles power management for Rockchip-based audio devices. However, a vulnerability has been identified in the way this module handles power management references during the resume process.
Vulnerability Detail
The vulnerability in the rockchip_i2s_tdm_resume module of the ASoC subsystem allows for incorrect usage of power management references. This issue can potentially lead to improper handling of power management operations during the resume process, resulting in unexpected behavior or system instability. An attacker with local access to the affected system could potentially exploit this vulnerability to manipulate power management operations and cause a denial of service (DoS) condition or execute arbitrary code with elevated privileges. The vulnerability was introduced in version v5.16 of the Linux Kernel and has been fixed in version v5.17.2.
