In the Linux kernel, the following vulnerability has been resolved:

udp: fix potential use-after-free in tunnel segmentation

__skb_udp_tunnel_segment() gets the UDP header before ensuring the

tunnel header is in the skb head. If the pull reallocates skb->head,

the saved UDP header pointer is no longer valid.

Get the UDP header after the pull to avoid a potential use-after-free. (NVD)
