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

mm/slub: fix to return errno if kmalloc() fails

In create_unique_id(), kmalloc(, GFP_KERNEL) can fail due to
out-of-memory, if it fails, return errno correctly rather than
triggering panic via BUG_ON();

kernel BUG at mm/slub.c:5893!
