7.5, "baseSeverity": "HIGH" }, "scenarios": [ { "lang": "en", "value": "AV:N - The vulnerable code is in the fabric-independent LIO SCSI target core, reached by parsing a PERSISTENT RESERVE OUT CDB and parameter list sent by a remote initiator; the flagship fabric (iscsi_target) accepts these over TCP/3260, so a remote peer on the network can deliver the malicious payload.\nAC:L - The attacker fully controls every precondition (service action, res_key=0, sa_res_key!=0, SPEC_I_PT bit, and the parameter list length/TransportID contents), and the NULL pointer is unconditionally present on the very first list entry, so a single malformed PR OUT command crashes the kernel deterministically with no race or memory-layout dependency.\nPR:N - LIO iSCSI targets are routinely deployed without CHAP, where the only \"credential\" is a self-asserted InitiatorName that is discoverable via a SendTargets discovery session, and demo-mode (generate_node_acls=1) grants any peer a mapped LUN outright — so an unauthenticated network attacker can establish the nexus needed to issue the command.\nUI:N - The crash is triggered purely by the attacker sending one SCSI command over an established I_T nexus; no action by any local user or administrator is needed.\nS:U - The NULL dereference occurs in the kernel that owns the target device and its impact is confined to that same kernel's security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:N - The fault is a read of a fixed small offset (se_deve->se_lun_acl) off a NULL pointer; no attacker-influenced offset, no out-of-bounds read, and no data is returned to the initiator, so nothing is disclosed.\nI:N - No memory is written and no attacker-controlled data reaches a store; the dereference faults on a read before any state modification, giving no write or control-flow primitive.\nA:H - The NULL pointer dereference produces a kernel oops (full panic with panic_on_oops) that can be re-triggered at will by an unauthenticated initiator, and the killed command context strands se_lun->lun_ref percpu references so the target subsystem hangs on teardown." } ] } ], "affected": [ { "product": "Linux",
