Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: scsi: target: Fix NULL pointer dereference in core_scsi3_decode_spec_i_port() The function core_scsi3_decode_spec_i_port(), in its error code path, unconditionally calls core_scsi3_lunacl_undepend_item() passing the dest_se_deve pointer, which may be NULL. This can lead to a NULL pointer dereference if dest_se_deve remains unset. SPC-3 PR SPEC_I_PT: Unable to locate dest_tpg Unable to handle kernel paging request at virtual address dfff800000000012 Call trace: core_scsi3_lunacl_undepend_item+0x2c/0xf0 [target_core_mod] (P) core_scsi3_decode_spec_i_port+0x120c/0x1c30 [target_core_mod] core_scsi3_emulate_pro_register+0x6b8/0xcd8 [target_core_mod] target_scsi3_emulate_pr_out+0x56c/0x840 [target_core_mod] Fix this by adding a NULL check before calling core_scsi3_lunacl_undepend_item()

\"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H\"}, \"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 \\u2014 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\u0027s 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-\u003ese_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-\u003elun_ref percpu references so the target subsystem hangs on teardown.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\":
