Description OSIDB Bzimport 2026-10-18 15:55:17 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ASoC: codecs: max98363: 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.
