CVE-2026-90060

Estado: RecibidaSin puntuar—

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

ALSA: control: Don't add invalid kcontrols to LED layer

The kcontrol LED state layer tries to track the all associated kcontrol elements with naive assumptions that they are readable. But one can create a write-only element that has no get callback (even a user element can do it), and this may lead to a NULL dereference at the call chain of snd_ctl_led_notify(), as found by syzkaller.

For avoiding the Oops, add a sanity check of the kcontrol's info and get callbacks, and just skip the invalid kcontrols before assigning the kctl to the LED layer.
