      "title": "vxlan: use pskb_network_may_pull() in route_shortcircuit()",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nvxlan: use pskb_network_may_pull() in route_shortcircuit()\n\nroute_shortcircuit() currently calls pskb_may_pull(skb, sizeof(struct iphdr))\n(or ipv6hdr), which checks if bytes are available starting from skb->data.\n\nHowever, in vxlan_xmit(), skb->data points to the MAC header, so\nskb_network_offset(skb) is ETH_HLEN (14 bytes). Using pskb_may_pull(skb, 20)\nonly checks 20 bytes from skb->data (which is 14 bytes MAC header + 6 bytes of\nIP header), leaving the rest of the IP header potentially un-pulled in non-linear\nfrags. Subsequent dereferences of ip_hdr(skb)->daddr can read beyond the pulled\nlinear buffer length.\n\nFix this by using pskb_network_may_pull(), which adds skb_network_offset(skb) to\nthe length check to ensure the full network header is present in the linear buffer.",
