      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: stmmac: fix TSO header length truncation\n\nstmmac_tso_xmit() stores the protocol header length returned by\nstmmac_tso_header_size() in a u8. stmmac_tso_valid_packet() admits\nheaders up to 1023 bytes, so a header longer than 255 bytes wraps modulo\n256 (486 becomes 230, 256 becomes 0).\n\nA TCP over IPv6 socket carrying a few hundred bytes of sticky\ndestination/hop-by-hop options makes skb_tcp_all_headers() exceed 255\nwhile staying below the 1023-byte limit, so such an skb reaches\nstmmac_tso_xmit().\n\nWiden proto_hdr_len to unsigned int, which is sufficient since the value\nis bounded by the hardware limit, and adjust the debug print specifier\naccordingly.",
