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.
