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."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/scsi/qla2xxx/qla_mbx.c"], "versions": [{"version": "41dc529a4602ac737020f423f84686a81de38e6d", "lessThan": "d3ac7e0f454c7d52c0c2e5ecaf5a3d938f1b166d", "status": "affected", "versionType": "git"}, {"version": "41dc529a4602ac737020f423f84686a81de38e6d", "lessThan": "40dcd4a71a52414b47fbba2f956387f1077c6c15", "status": "affected", "versionType": "git"}, {"version": "41dc529a4602ac737020f423f84686a81de38e6d", "lessThan": "20bb54601d2655e83795b73499c89f6b1cb31016", "status": "affected", "versionType": "git"}, {"version": "41dc529a4602ac737020f423f84686a81de38e6d", "lessThan": "d61e8de98c5a52978fb1edd95fe4dde3131b280e", "status": "affected", "versionType": "git"}, {"version": "41dc529a4602ac737020f423f84686a81de38e6d", "lessThan": "7a83979d92782f83c90888ebe19bdc9420521940", "status": "affected", "versionType": "git"}, {"version": "41dc529a4602ac737020f423f84686a81de38e6d", "lessThan": "23582731afa35031c94fadb71a4f3b4afd094649", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/scsi/qla2xxx/qla_mbx.c"], "versions": [{"version": "4.11", "status": "affected"}, {"version": "0", "lessThan": "4.11", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.191", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.160", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.112", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.53", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2.7", "lessThanOrEqual": "7.2.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.3", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.11", "versionEndExcluding": "6.1.191"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.11", "versionEndExcluding": "6.6.160"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.11", "versionEndExcluding": "6.12.112"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.11", "versionEndExcluding": "6.18.53"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.11", "versionEndExcluding": "7.2.7"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.11", "versionEndExcluding": "7.3"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/d3ac7e0f454c7d52c0c2e5ecaf5a3d938f1b166d"}, {"url": "https://git.kernel.org/stable/c/40dcd4a71a52414b47fbba2f956387f1077c6c15"}, {"url": "https://git.kernel.org/stable/c/20bb54601d2655e83795b73499c89f6b1cb31016"}, {"url": "https://git.kernel.org/stable/c/d61e8de98c5a52978fb1edd95fe4dde3131b280e"}, {"url": "https://git.kernel.org/stable/c/7a83979d92782f83c90888ebe19bdc9420521940"}, {"url": "https://git.kernel.org/stable/c/23582731afa35031c94fadb71a4f3b4afd094649"}], "title": "scsi: qla2xxx: Skip vport under deletion in report ID acquisition", "x_generator": {"engine": "bippy-1.2.0"}}}}
