# CVE-2026-64486

> 3.1 LOW

## Beschreibung

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.

## Patch verfügbar (OSV)

- Kernel ≥ 6.1.178
- Kernel ≥ 6.6.145
- Kernel ≥ 6.12.96
- Kernel ≥ 6.18.39
- Kernel ≥ 7.1.4
