Background
The soundwire package is a component of the Linux Kernel that provides support for SoundWire audio interfaces. SoundWire is a digital audio bus technology used for connecting audio devices in embedded systems. It enables high-quality audio streaming and control between devices. The stream configuration functionality in soundwire is responsible for setting up and managing audio streams between devices.
Vulnerability Detail
This vulnerability in the soundwire package allows for a memory leak in the stream configuration error path. When an error occurs during the configuration of an audio stream, memory allocated for the stream configuration is not properly freed, leading to a memory leak. An attacker could potentially exploit this vulnerability by repeatedly triggering stream configuration errors, causing a gradual depletion of available memory resources. This could result in a denial-of-service (DoS) condition or other unexpected system behavior.
