ALSA: gus: check snd_ctl_new1() return value
Published Jul 25, 2026

EPSS 0.21%
Description
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.
