QLogic CNAs speak FCoE and SAN fabrics are stretched via FCIP, so a compromised target delivers late completions over the storage network with no local access.\nAC:L - A hostile target controls FCP_RSP timing and can delay a response until SCSI error handling aborts and returns the command, then complete so firmware posts status for a NULL cmd. The same function already handles that case (\"Command already returned\"); the crash is then deterministic and needs no rare config or layout beyond a qla2xxx HBA.\nPR:N - Completions are handled in the HBA interrupt/response-queue path (qla24xx_process_response_queue to qla2x00_status_entry) with no Linux credential or capability check; the attacker only needs to act as an FC/FCoE target on the fabric.\nUI:N - Once the target is visible on the fabric, the SCSI midlayer automatically issues commands (scan, path checks, mounted-filesystem I/O) whose STATUS_TYPE completions take the vulnerable path; no user mount, open, or other interactive step is required at exploit time.\nS:U - The NULL dereference and resulting oops stay inside the host kernel that owns the qla2xxx driver and do not cross a VM, IOMMU, or other separate security authority.\nC:N - This is a pure NULL-pointer dereference of GET_CMD_SP(sp) (cmd->sc_data_direction at a NULL-page offset) when the SCSI command was already returned or aborted. There is no use-after-free of a live object, out-of-bounds read, or other kernel memory disclosure primitive.\nI:N - The cmd pointer is NULL, not a freed or attacker-controlled object, so the load cannot corrupt kernel heap, overwrite function pointers, or hijack control flow. The fix is only an early NULL return; there is no write primitive.\nA:H - Dereferencing NULL cmd in qla_chk_edif_rx_sa_delete_pending() from the response-queue interrupt or qla_do_work() context oopses or panics the host, taking down all storage served by the adapter. A fabric peer can repeat this on aborted I/O."}]}], "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_edif.c"], "versions": [{"version": "dd30706e73b70d67e88fdaca688db7a3374fd5de", "lessThan": "e479e9b148456905d12711411484b94083c8ff58", "status": "affected", "versionType": "git"}, {"version": "dd30706e73b70d67e88fdaca688db7a3374fd5de", "lessThan": "2191b0034a2f1307d421782e6eceddf8eec9e7f6", "status": "affected", "versionType": "git"}, {"version": "dd30706e73b70d67e88fdaca688db7a3374fd5de", "lessThan": "de0c8ef3b900c5e971c82ef38c6f5c22c5f3d8c1", "status": "affected", "versionType": "git"}, {"version": "dd30706e73b70d67e88fdaca688db7a3374fd5de", "lessThan": "96eb8a3fc9f7fe7ba32679fcf1d2fd7d251e7a8b", "status": "affected", "versionType": "git"}, {"version": "dd30706e73b70d67e88fdaca688db7a3374fd5de", "lessThan": "94bfb61478bcb207d27f8cd24fd231421059519f", "status": "affected", "versionType": "git"}, {"version": "dd30706e73b70d67e88fdaca688db7a3374fd5de", "lessThan": "75fd6d041c4a325ae37f4683e6678d3015988bb0", "status": "affected", "versionType": "git"}, {"version": "dd30706e73b70d67e88fdaca688db7a3374fd5de", "lessThan": "c20ee380ca59c5a8646750c4849969a815924e2e", "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_edif.c"], "versions": [{"version": "5.15", "status": "affected"}, {"version": "0", "lessThan": "5.15", "status": "unaffected", "versionType": "semver"}, {"version": "5.15.221", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.188", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.157", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.110", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.51", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2.5", "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": "5.15", "versionEndExcluding": "5.15.221"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "6.1.188"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "6.6.157"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "6.12.110"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "6.18.51"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "7.2.5"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "7.3"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/e479e9b148456905d12711411484b94083c8ff58"}, {"url": "https://git.kernel.org/stable/c/2191b0034a2f1307d421782e6eceddf8eec9e7f6"}, {"url": "https://git.kernel.org/stable/c/de0c8ef3b900c5e971c82ef38c6f5c22c5f3d8c1"}, {"url": "https://git.kernel.org/stable/c/96eb8a3fc9f7fe7ba32679fcf1d2fd7d251e7a8b"}, {"url": "https://git.kernel.org/stable/c/94bfb61478bcb207d27f8cd24fd231421059519f"}, {"url": "https://git.kernel.org/stable/c/75fd6d041c4a325ae37f4683e6678d3015988bb0"}, {"url": "https://git.kernel.org/stable/c/c20ee380ca59c5a8646750c4849969a815924e2e"}], "title": "scsi: qla2xxx: edif: Fix NULL pointer deref in RX SA delete check", "x_generator": {"engine": "bippy-1.2.0"}}}}
