Description OSIDB Bzimport 2026-07-25 10:07:57 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ALSA: cmipci: check snd_ctl_new1() return value

snd_ctl_new1() can return NULL when memory allocation fails.
snd_cmipci_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.
