      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nsvcrdma: Clear sc_cm_id when ADDR_CHANGE replacement fails\n\nWhen svc_rdma_listen_handler() handles RDMA_CM_EVENT_ADDR_CHANGE,\nit creates a replacement listener cm_id and returns 1, telling\nthe CM core to destroy the old one. If the replacement allocation\nfails, sc_cm_id still points at the old cm_id that the CM core is\nabout to destroy. Any subsequent dereference of sc_cm_id --\nsuch as svc_rdma_detach()'s rdma_disconnect() call -- is a\nuse-after-free.\n\nNULL sc_cm_id on the failure path and guard svc_rdma_detach()'s\nrdma_disconnect() call against NULL so that the listener can\nbe torn down safely when the server shuts down.",
