      "title": "sctp: validate stream count in sctp_process_strreset_inreq()",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nsctp: validate stream count in sctp_process_strreset_inreq()\n\nWhen processing a RESET_IN_REQUEST from a peer,\nsctp_process_strreset_inreq() derives the stream count from the\nparameter length but does not check whether the resulting\nRESET_OUT_REQUEST would exceed SCTP_MAX_CHUNK_LEN.\n\nThe OUT request header (sctp_strreset_outreq, 16 bytes) is 8 bytes\nlarger than the IN request header (sctp_strreset_inreq, 8 bytes).\nGenerally, the IP payload is bounded to 65535 bytes, so the stream\nlist cannot be large enough to trigger the overflow. However, on\ninterfaces with MTU > 65535 (e.g., loopback with IPv6 jumbograms), a\nstream list that fits within the incoming IN parameter can cause a\n__u16 overflow in sctp_make_strreset_req() when computing the OUT\nrequest size, leading to an undersized skb allocation and a kernel\nBUG:\n\n  net/core/skbuff.c:207         skb_panic\n  net/core/skbuff.c:2625        skb_put\n  net/sctp/sm_make_chunk.c:1535 sctp_addto_chunk\n  net/sctp/sm_make_chunk.c:3695 sctp_make_strreset_req\n  net/sctp/stream.c:655         sctp_process_strreset_inreq\n\nThe local setsockopt path validates the generated reset request size.\nHowever, for an incoming-only reset, it accounts for the smaller IN\nrequest even though the peer must generate an OUT request with the same\nstream list. Such a request cannot be completed successfully by the\npeer.\n\nReject peer IN requests whose corresponding OUT request would exceed\nSCTP_MAX_CHUNK_LEN. Also tighten the local check so it does not send an\nIN request that would require an oversized OUT request from the peer.",
