CVE-2024-36952 is an incomplete-cleanup vulnerability in the Linux kernel SCSI lpfc driver's NPIV virtual-port deletion path. Premature transport unregistration invokes fc_remove_host(), which calls dev_loss_tmo for all D_IDs, including the fabric D_ID, and can release the final ndlp reference and free the ndlp rport object. A race can consequently prevent the final Remove All DA_ID CT and LOGO ELS requests from being sent, leaving the Fibre Channel fabric switch incorrectly treating the deleted virtual port as still logged in.
