The keyctl_read_key function in security/keys/keyctl.c in the Key
Management subcomponent in the Linux kernel before 4.13.5 does not properly
consider that a key may be possessed but negatively instantiated, which
allows local users to cause a denial of service (OOPS and system crash) via
a crafted KEYCTL_READ operation.
