In the Linux kernel, the following vulnerability has been resolved:gro: fix ownership transferIf packets are GROed with fraglist they might be segmented later on and
continue their journey in the stack. In skb_segment_list those skbs can
be reused as-is. This is an issue as their destructor was removed in
skb_gro_receive_list but not the reference to their socket, and then
they can't be orphaned. Fix this by also removing the reference to the
socket.For example this could be observed,kernel BUG at include/linux/skbuff.h:3131!  (skb_orphan)
