ASoC: rt1017-sdca-sdw Uninitialized Stream Type Fix

Publication date: 2026-10-18

Last updated on: 2026-10-18

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: rt1017-sdca-sdw: fix uninitialized stream_config->type stream_config is not initialized before being passed to sdw_stream_add_slave(). The type field may contain garbage and is later copied to stream->type by sdw_config_stream(). Zero-initialize stream_config so type defaults to SDW_STREAM_PCM. While at it, use snd_sdw_params_to_config() helper instead of open-coding the same logic.

Executive Summary

This vulnerability is in the Linux kernel's ASoC (ALSA System on Chip) codec driver for the rt1017-sdca-sdw codec. It involves an uninitialized variable where the stream_config structure's type field may contain garbage values. This could lead to incorrect stream type handling in the SoundWire subsystem.

Impact Analysis

This could cause audio subsystem malfunctions, including distorted sound, device failures, or system crashes. It may affect systems using the rt1017-sdca-sdw codec with SoundWire audio interfaces.

Mitigation Strategies

Update the Linux kernel to the patched version where stream_config is properly initialized. Check for kernel updates from your distribution vendor that include the fix for CVE-2026-98743.
