CVE-2026-64489

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ALSA: ymfpci: check snd_ctl_new1() return value<br /> <br /> snd_ctl_new1() can return NULL when memory allocation fails.<br /> snd_ymfpci_create_spdif_controls() does not check the return value<br /> before dereferencing kctl-&gt;id.device, which can lead to a NULL pointer<br /> dereference.<br /> <br /> Add NULL checks after snd_ctl_new1() calls and return -ENOMEM if any<br /> fails.
