Linux kernel built with the 802.1Q/802.1ad VLAN(CONFIG_VLAN_8021Q) OR Virtual eXtensible Local Area Network(CONFIG_VXLAN) with Transparent Ethernet Bridging(TEB) GRO support, is vulnerable to a stack overflow issue. It could occur while receiving large packets via GRO path, as an unlimited recursion could unfold in both VLAN and TEB modules, leading to a stack corruption in the kernel.
