Doc Text:	A flaw was found in the Linux kernel's Advanced Linux Sound Architecture (ALSA) ice1712 driver. This vulnerability occurs because the `snd_ctl_new1()` function, which allocates memory, can return a null value upon failure, but the driver does not properly check for this. An attacker could potentially trigger a memory allocation failure, leading to a null pointer dereference and causing the system to crash, resulting in a Denial of Service (DoS).	Story Points:	---

Description OSIDB Bzimport 2026-07-25 10:07:28 UTC

In the Linux kernel, the following vulnerability has been resolved:

ALSA: ice1712: check snd_ctl_new1() return value

snd_ctl_new1() can return NULL when memory allocation fails. The
ice1712 driver calls snd_ctl_new1() without checking the return value
before dereferencing the pointer in multiple places (ice1712.c,
ice1724.c, aureon.c), which can lead to NULL pointer dereferences.

Add NULL checks after snd_ctl_new1() calls and return -ENOMEM if any
fails.
