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...

The vulnerability of the skb_gro_receive_list() function in the net/core/gro.c module, which is part of Linux’s kernel-based networking functions, allows a hacker to cause a service failure.

The vulnerability of the skbgroreceivelist function in the net/core/gro.c module of the Linux kernel’s networking functions is related to the occurrence of operations outside the buffer in memory. Exploiting this vulnerability could allow a remote attacker to cause service interruptions...
