Description

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.
