Mitigation checklist

Recommended fix / mitigation
  • This vulnerability requires the NFS/RDMA server to be running with CONFIG_SUNRPC_XPRT_RDMA enabled, which requires RDMA hardware (InfiniBand or RoCE). Systems that do not have RDMA hardware or do not export NFS over RDMA are not affected. If NFS/RDMA is not required, disabling or not loading the svcrdma kernel module prevents exploitation.
