bpf: reject short IPv4/IPv6 inputs in bpf_prog_test_run_skb
In the Linux kernel, the following vulnerability has been resolved: bpf: reject short IPv4/IPv6 inputs in bpf_prog_test_run_skb bpf_prog_test_run_skb() calls eth_type_trans() first and then uses skb->protocol to initialize sk family and address fields for the test run. For IPv4 and IPv6 packets, it may access ip_hdr(skb) or ipv6_hdr(skb) even when the provided test input only contains an Ethernet header. Reject the input earlier if the Ethernet frame carries IPv4/IPv6 EtherType but the L3 header is too short. Fold the IPv4/IPv6 header length checks into the existing protocol switch and return -EINVAL before accessing the network headers.
