Vulnerability Name:

CCN-111001

Published:2016-02-19
Updated:2016-02-19
Summary:Linux Kernel could allow a local attacker to gain elevated privileges on the system, caused by an integer overflow in the L2TP PPP sendmsg implementation. An attacker could exploit this vulnerability using an overly large size parameter to gain elevated privileges on the system.
