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.
