In the Linux kernel, the following vulnerability has been resolved:
vrf: use RCU protection in l3mdev_l3_out()
l3mdev_l3_out() can be called without RCU being held:
raw_sendmsg()
ip_push_pending_frames()
ip_send_skb()
ip_local_out()
__ip_local_out()
l3mdev_ip_out()
Add rcu_read_lock() / rcu_read_unlock() pair to avoid
a potential UAF.
