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