Summary In the Linux kernel, the following vulnerability has been resolved: ASoC: soc-core: care NULL dirver name on snd_soc_lookup_component_nolocked() soc-generic-dmaengine-pcm.c uses same dev for both CPU and Platform. In such case, CPU component driver might not have driver->name, then snd_soc_lookup_component_nolocked() will be NULL pointer access error. Care NULL driver name.
