Description

In pppol2tp_connect, there is possible memory corruption due to a use after free. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: Android kernel. Android ID: A-38159931.
A race condition between pppol2tp_session_create() and l2tp_eth_create() in net/l2tp/l2tp_netlink.c was found in the Linux kernel. Calling l2tp_tunnel_find() may result in a new tunnel being created with tunnel id of a previously removed tunnel which wouldn't be protected by the reference counter.
