In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
svcrdma: Clear sc_cm_id when ADDR_CHANGE replacement fails<\/p>\n
When 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.<\/p>\n
NULL 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
