In the Linux kernel, the following vulnerability has been resolved:
ALSA: aoa: check snd_ctl_new1() return value
snd_ctl_new1() can return NULL when memory allocation fails. In
layout.c, the function does not check the return value before
dereferencing ctl->id.name or passing to aoa_snd_ctl_add(), which can
lead to a NULL pointer dereference.
Add NULL checks after snd_ctl_new1() calls and return early if any
fails.
