Description

In the Linux kernel, the following vulnerability has been resolved:

ALSA: gus: check snd_ctl_new1() return value

snd_ctl_new1() can return NULL when memory allocation fails. snd_gf1_pcm_volume_control() does not check the return value before dereferencing kctl->id.index, which can lead to a NULL pointer dereference.

Add a NULL check after snd_ctl_new1() and return -ENOMEM if it fails.
