  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nxprtrdma: Initialize re_id before removal registration\n\nrpcrdma_create_id() registers ep-\u003ere_rn with the rpcrdma ib_client\nbefore returning the new rdma_cm_id to rpcrdma_ep_create(). However\nrpcrdma_ep_create() currently stores that pointer in ep-\u003ere_id only\nafter rpcrdma_create_id() returns.\n\nA local administrator can race an NFS/RDMA mount against RDMA device\nremoval. If rpcrdma_remove_one() observes the just-registered\nnotification before rpcrdma_ep_create() assigns ep-\u003ere_id,\nrpcrdma_ep_removal_done() calls trace_xprtrdma_device_removal(NULL).\nThe tracepoint dereferences id-\u003edevice-\u003ename and copies\nid-\u003eroute.addr.dst_addr, so the callback can crash the kernel with a\nNULL pointer dereference.\n\nStore the rdma_cm_id in ep-\u003ere_id immediately before publishing\nep-\u003ere_rn. The existing error path still destroys the id directly if\nregistration fails; ep is then freed by the caller without using\nep-\u003ere_id. Remove the later duplicate assignment in rpcrdma_ep_create().",
