Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2016-2854
CWEhttps://cwe.mitre.org/data/definitions/269.html

The aufs module for the Linux kernel 3.x and 4.x does not properly maintain POSIX ACL xattr data, which allows local users to gain privileges by leveraging a group-writable setgid directory.

Weakness

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
