Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2014-4943
CWEhttps://cwe.mitre.org/data/definitions/269.html

The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the Linux kernel through 3.15.6 allows local users to gain privileges by leveraging data-structure differences between an l2tp socket and an inet socket.

Weakness

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