  "summary": "xprtrdma: Check frwr_wp_create() during connect",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nxprtrdma: Check frwr_wp_create() during connect\n\nfrwr_wp_create() creates the singleton Memory Region used to encode\npadding for Write chunks whose payload length is not XDR-aligned. Its\nfailure paths return a negative errno and leave ep->re_write_pad_mr set\nto NULL.\n\nrpcrdma_xprt_connect() currently ignores that return value. If\nfrwr_wp_create() fails after the rest of the connection setup succeeds,\nxprt_rdma_connect_worker() treats the connection attempt as successful\nand sets XPRT_CONNECTED. A later NFS/RDMA read with a non-4-byte-aligned\nreceive page length reaches rpcrdma_encode_write_list(), passes the NULL\nwrite-pad MR to encode_rdma_segment(), and dereferences it.\n\nThis is locally triggerable on an NFS/RDMA client after a connect or\nreconnect hits a local MR allocation, DMA-map, MR-map, or post-send\nfailure; a remote peer alone cannot force the local MR setup failure.\n\nCheck the return value and fail the connect as -ENOTCONN, matching the\nadjacent setup failures. This keeps XPRT_CONNECTED clear and lets the\nnormal reconnect path retry.",
