CVE-2026-98743
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:
ASoC: codecs: rt1017-sdca-sdw: corrige stream_config->type sin inicializar
stream_config no se inicializa antes de pasarlo a sdw_stream_add_slave(). El campo type puede contener basura y después se copia en stream->type mediante sdw_config_stream().
Inicializa a cero stream_config para que type tome por defecto SDW_STREAM_PCM.
Aprovechando el cambio, usa el helper snd_sdw_params_to_config() en lugar de reescribir la misma lógica en línea.
