      "title": "IB/mad: Drop unmatched RMPP responses before reassembly",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nIB/mad: Drop unmatched RMPP responses before reassembly\n\nKernel-handled RMPP receive processing starts reassembly for active\nDATA responses before the response is matched to an outstanding send.\nThe normal match happens later, after ib_process_rmpp_recv_wc() has\neither assembled a complete message or consumed the segment.\n\nThat ordering lets an unsolicited response that routes to a kernel\nRMPP agent by the high TID bits allocate or extend RMPP receive state\nbefore the full TID and source address are checked against a real\nrequest. A reordered burst can therefore reach the receive-side\ninsertion path even though the response would not match any send.\n\nFor kernel-handled RMPP DATA responses, require the existing\nib_find_send_mad() match before entering RMPP reassembly. The matcher\nalready checks the full TID, management class and source address/GID\nagainst the agent wait, backlog and in-flight send lists. If there is\nno match, drop the response without creating RMPP state.\n\nThis leaves the RMPP window behavior unchanged and only rejects\nresponses that have no corresponding request.",
