CVE-2014-4943
Published: 16 July 2014
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.
From the Ubuntu security team
Sasha Levin reported a flaw in the Linux kernel's point-to-point protocol (PPP) when used with the Layer Two Tunneling Protocol (L2TP). A local user could exploit this flaw to gain administrative privileges.
