Summary
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.
