      "title": "net: gso: fix tcp fraglist segmentation after pull from frag_list",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: gso: fix tcp fraglist segmentation after pull from frag_list\n\nDetect tcp gso fraglist skbs with corrupted geometry (see below) and\npass these to skb_segment instead of skb_segment_list, as the first\ncan segment them correctly.\n\nValid SKB_GSO_FRAGLIST skbs\n- consist of two or more segments\n- the head_skb holds the protocol headers plus first gso_size\n- one or more frag_list skbs hold exactly one segment\n- all but the last must be gso_size\n\nOptional datapath hooks such as NAT and BPF (bpf_skb_pull_data) can\nmodify these skbs, breaking these invariants.\n\nIn extreme cases they pull all data into skb linear. For TCP, this\ncauses a NULL ptr deref in __tcpv4_gso_segment_list_csum at\ntcp_hdr(seg->next).\n\nDetect invalid geometry due to pull, by checking head_skb size.\nDon't just drop, as this may blackhole a destination. Convert to be\nable to pass to regular skb_segment.\n\nApproach and description based on a patch by Willem de Bruijn.",
