security/keys/keyctl.c in the Linux kernel before 4.11.5 does not consider
the case of a NULL payload in conjunction with a nonzero length value,
which allows local users to cause a denial of service (NULL pointer
dereference and OOPS) via a crafted add_key or keyctl system call, a
different vulnerability than CVE-2017-12192.
