In the Linux kernel, the following vulnerability has been resolved:
ASoC: core: Check for rtd == NULL in snd_soc_remove_pcm_runtime()
snd_soc_remove_pcm_runtime() might be called with rtd == NULL which will
leads to null pointer dereference.
This was reproduced with topology loading and marking a link as ignore
due to missing hardware component on the system.
On module removal the soc_tplg_remove_link() would call
snd_soc_remove_pcm_runtime() with rtd == NULL since the link was ignored,
no runtime was created.
