A fix is available — apply it.

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

ALSA: ymfpci: check snd_ctl_new1() return value

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

Add NULL checks after snd_ctl_new1() calls and return -ENOMEM if any fails.
