CVE-2026-23376

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> nvmet-fcloop: Check remoteport port_state before calling done callback<br /> <br /> In nvme_fc_handle_ls_rqst_work, the lsrsp-&gt;done callback is only set when<br /> remoteport-&gt;port_state is FC_OBJSTATE_ONLINE. Otherwise, the<br /> nvme_fc_xmt_ls_rsp&amp;#39;s LLDD call to lport-&gt;ops-&gt;xmt_ls_rsp is expected to<br /> fail and the nvme-fc transport layer itself will directly call<br /> nvme_fc_xmt_ls_rsp_free instead of relying on LLDD&amp;#39;s done callback to free<br /> the lsrsp resources.<br /> <br /> Update the fcloop_t2h_xmt_ls_rsp routine to check remoteport-&gt;port_state.<br /> If online, then lsrsp-&gt;done callback will free the lsrsp. Else, return<br /> -ENODEV to signal the nvme-fc transport to handle freeing lsrsp.
