kernel: net: add pskb_may_pull() to skb_gro_receive_list()

A flaw was found in the Linux kernel's network Generic Receive Offload GRO handling. An attacker sending specially crafted network packets could trigger a bug in the skbgroreceivelist function. This occurs when the system attempts to process network data that is not in the expected linear memory...
