In the Linux kernel, the following vulnerability has been resolved:
ALSA: ac97: fix a double free in snd_ac97_controller_register()
If ac97_add_adapter() fails, put_device() is the correct way to drop the device reference. kfree() is not required. Add kfree() if idr_alloc() fails and in ac97_adapter_release() to do the cleanup.
Found by code review.
