The Linux kernel before 4.5 allows local users to bypass file-descriptor
limits and cause a denial of service (memory consumption) by leveraging
incorrect tracking of descriptor ownership and sending each descriptor over
a UNIX socket before closing it. NOTE: this vulnerability exists because of
an incorrect fix for CVE-2013-4312.
