CVE-2026-64484
In the Linux kernel, the following vulnerability has been resolved:
ALSA: es1938: check snd_ctl_new1() return value
snd_ctl_new1() can return NULL when memory allocation fails.
snd_es1938_mixer() does not check the return value before dereferencing
the pointer, which can lead to a NULL pointer dereference.
Add a NULL check after snd_ctl_new1() and return -ENOMEM if it fails.
