Summary

The Linux kernel ASoC max98363 codec driver passes an uninitialized stream_config structure to sdw_stream_add_slave(). Its type field may contain garbage, which sdw_config_stream() later copies to the stream type. The fix zero-initializes the structure so the type defaults to SDW_STREAM_PCM. The affected range starts at Linux kernel 6.4.

Description from the CNA

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.
