  "details": "In the Linux kernel, the following vulnerability has been resolved:  RDMA/mad: Fix receive buffer leak when PKey enforcement fails  ib_mad_complete_recv() initializes mad_recv_wc-\u003ermpp_list and then runs ib_mad_enforce_security() before linking recv_buf onto that list.  On failure it calls ib_free_recv_mad(), which only walks rmpp_list and frees the ib_mad_private of every buffer found there.  As the list is still empty at that point, nothing is freed at all.  The caller cannot clean up either: ib_mad_recv_done() sets recv to NULL right after ib_mad_complete_recv() returns, assuming the MAD layer took ownership of the buffer.  Every MAD that fails the PKey check therefore leaks one ib_mad_private (about 300 bytes per IB port MAD, ~2K for OPA), and a remote node can trigger this repeatedly by sending MADs with a wrong PKey.  Link recv_buf onto rmpp_list right after the list is initialized, so the error path has something to free.",
