Out-of-bounds write in Linux kernel's ipvlan network driver

A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to achieve local privilege escalation.

The out-of-bounds write is caused by missing skb->cb  initialization in the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled.
