  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Skip vport under deletion in report ID acquisition\n\nqla24xx_report_id_acquisition() format-1 handling walks ha->vp_list under\nvport_slock, takes a vref_count on the matching vport and calls\nqla_update_host_map() to register its port id.\n\nA vport teardown via qla24xx_vport_delete() sets VPORT_DELETE, then\nqla24xx_disable_vp() removes the vport from the host_map btree and zeroes\nvha->d_id (RESET_AL_PA). The vport is only unlinked from vp_list later,\nin qla24xx_deallocate_vp_id(), which clears vp_map[idx] (RESET_VP_IDX)\nbut does not touch host_map. In the window in between, report ID\nacquisition can still find the vport on vp_list and call\nqla_update_host_map(); with d_id already zeroed it takes the\nbtree_insert32() path and re-inserts the dying vport into host_map.\nNothing cleans that entry afterwards, so once scsi_host_put() frees the\nvha a later host_map lookup dereferences freed memory.\n\nSkip a vport that has VPORT_DELETE set before taking the reference, so it\nis neither re-registered nor scheduled for DPC re-registration. This\nmirrors the existing guard in qla2x00_alert_all_vps().",

      "scenario": "AV:A - The patched format-1 (vp_idx != 0) path in qla24xx_report_id_acquisition() walks ha->vp_list and calls qla_update_host_map() when a VP_RPT_ID_IOCB_TYPE for FDISC complete or VP_STAT_ID_CHG arrives via qla24xx_process_response_queue() from qla24xx_intr_handler/qla24xx_msix_rsp_q, or via qlt_24xx_atio_pkt_all_vps(). A Fibre Channel SAN peer or switch induces those RIDAs; native FC/FCoE is a non-routable L2 fabric, so Adjacent.\nAC:H - The stale host_map insert happens only after qla24xx_vport_delete() sets VPORT_DELETE and qla24xx_disable_vp() RESET_AL_PA zeroes d_id and drops the vport from host_map, but before qla24xx_deallocate_vp_id() unlinks it from vp_list. A fabric attacker cannot write the S_IWUSR sysfs store_fc_vport_delete attribute to start that teardown, so the window is a victim state they cannot induce.\nPR:N - VP_RPT_ID handling in qla24xx_process_response_queue() and qlt_24xx_atio_pkt_all_vps() is an unauthenticated firmware completion of fabric N_Port ID assignment; that interrupt path checks no Linux uid or capability. FC-SP/EDIF is opt-in and is not required to deliver a format-1 RIDA.\nUI:N - Format-1 RIDA is processed automatically in interrupt context when firmware reports a VP ID. Concurrent qla24xx_vport_delete() is an administrator NPIV teardown rather than a mount, open, or other interactive step the attacker solicits.\nS:U - The dangling scsi_qla_host pointer is stored in ha->host_map and later consumed in the same host kernel by qla_find_host_by_d_id(); this does not cross a VM, IOMMU, or sandbox boundary.\nC:H - After scsi_host_put() at the end of qla24xx_vport_delete() frees the vha, a later btree_lookup32() in qla_find_host_by_d_id() on the re-inserted host_map key returns the freed scsi_qla_host. That use-after-free enables disclosure of reused heap contents.\nI:H - With d_id already zeroed, qla_update_host_map() takes btree_insert32() and plants the dying vha into ha->host_map. Later ATIO/ELS dispatch via qla_find_host_by_d_id() writes through that freed scsi_qla_host, giving a kernel write and control-flow primitive.\nA:H - A later host_map lookup of the freed vha from qlt_24xx_atio_pkt_all_vps() (ATIO_TYPE7 d_id) or qla_edif ELS handling oopses in interrupt context, panicking the storage host even without a full exploit."
