  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: control: Don't add invalid kcontrols to LED layer\n\nThe kcontrol LED state layer tries to track the all associated\nkcontrol elements with naive assumptions that they are readable.\nBut one can create a write-only element that has no get callback (even\na user element can do it), and this may lead to a NULL dereference at\nthe call chain of snd_ctl_led_notify(), as found by syzkaller.\n\nFor avoiding the Oops, add a sanity check of the kcontrol's info and\nget callbacks, and just skip the invalid kcontrols before assigning\nthe kctl to the LED layer.",
