  "description": "In the Linux kernel, the following vulnerability has been resolved:  nvmet-fcloop: Check remoteport port_state before calling done callback  In nvme_fc_handle_ls_rqst_work, the lsrsp-\u003Edone callback is only set when remoteport-\u003Eport_state is FC_OBJSTATE_ONLINE.  Otherwise, the nvme_fc_xmt_ls_rsp\u0027s LLDD call to lport-\u003Eops-\u003Exmt_ls_rsp is expected to fail and the nvme-fc transport layer itself will directly call nvme_fc_xmt_ls_rsp_free instead of relying on LLDD\u0027s done callback to free the lsrsp resources.  Update the fcloop_t2h_xmt_ls_rsp routine to check remoteport-\u003Eport_state. If online, then lsrsp-\u003Edone callback will free the lsrsp.  Else, return -ENODEV to signal the nvme-fc transport to handle freeing lsrsp.",
