attempting to access another processes pagemep in proc.


* CVE-2016-7039: Kernel crash due to unbounded recursion in vlan GRO processing.

Linux kernel built with the 802.1Q/802.1ad VLAN OR Virtual eXtensible LAN
with Transparent Ethernet Bridging(TEB) GRO support, is vulnerable to a stack
overflow issue, leading to a stack corruption in the kernel.

packets to a server that has GRO enabled.
