Mitre

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

staging: greybus: lights: avoid NULL deref

gb lights light config() stores channel count before allocating the channels array. If kcalloc() fails, gb lights release() iterates the non-zero count and dereferences light->channels, which is NULL.

Allocate channels first and only then publish channels count so the cleanup path can't walk a NULL pointer.
