CVE-2026-64489 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ALSA: ymfpci: check snd_ctl_new1() return value snd_ctl_new1() can return NULL when memory allocation fails. snd_ymfpci_create_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.
A vulnerability in the Linux kernel's ALSA ymfpci driver can lead to a NULL pointer dereference. The issue arises in the function 'snd_ymfpci_create_spdif_controls()', which fails to check the return value of 'snd_ctl_new1()' before accessing 'kctl->id.device'. This oversight can cause a crash if memory allocation fails. The vulnerability affects the Linux kernel stable group.
The vulnerability has been addressed by adding NULL checks after the 'snd_ctl_new1()' calls and returning -ENOMEM if any allocation fails. Users should upgrade to the latest version of the Linux kernel where this fix has been applied.
