Description

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.
