  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnvmet-fcloop: Check remoteport port_state before calling done callback\n\nIn nvme_fc_handle_ls_rqst_work, the lsrsp-\u003edone callback is only set when\nremoteport-\u003eport_state is FC_OBJSTATE_ONLINE.  Otherwise, the\nnvme_fc_xmt_ls_rsp's LLDD call to lport-\u003eops-\u003exmt_ls_rsp is expected to\nfail and the nvme-fc transport layer itself will directly call\nnvme_fc_xmt_ls_rsp_free instead of relying on LLDD's done callback to free\nthe lsrsp resources.\n\nUpdate the fcloop_t2h_xmt_ls_rsp routine to check remoteport-\u003eport_state.\nIf online, then lsrsp-\u003edone callback will free the lsrsp.  Else, return\n-ENODEV to signal the nvme-fc transport to handle freeing lsrsp.",
