"value": "AV:L - `bus_register()` is a driver-core API invoked only from subsystem initialization running on the local machine; the unprivileged trigger is a local `socket(AF_NETLINK, SOCK_RAW, NETLINK_ISCSI)` syscall that forces module autoload. No remote peer, network packet, or physical device is involved.\nAC:L - The attacker can drive the system into memory pressure and then repeatedly force `scsi_transport_iscsi` autoload, because a failed module init leaves the netlink protocol unregistered so the request_module can be replayed without limit until an allocation inside `bus_register()` fails. Nothing about the trigger depends on state outside the attacker\u0027s influence, and the two `kfree()` calls then execute back-to-back deterministically.\nPR:L - `netlink_create()` performs `request_module(\"net-pf-16-proto-8\")` with no capability check at all, so an ordinary unprivileged user reaches `iscsi_transport_init()` \u2192 `bus_register(\u0026iscsi_flashnode_bus)` with a single socket() call. No CAP_SYS_MODULE, no root, and no user-namespace trickery is needed for this path.\nUI:N - The attacker performs every step itself \u2014 create memory pressure, issue the socket() call that triggers autoload \u2014 with no victim action, mount, file open, or administrator involvement required.\nS:U - The corrupted object is a kernel slab allocation and the consequences stay entirely within the kernel\u0027s own security authority; no VM, hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The double free makes the SLUB freelist self-referential so two later allocations of the same size class alias one address, giving type confusion between attacker-controlled and kernel objects and thus an arbitrary kernel-memory read primitive. Freed-object contents can be reclaimed and disclosed through the aliased structure.\nI:H - The same freelist aliasing lets an attacker-sprayed object overwrite the fields of an unrelated live kernel structure \u2014 including function pointers reachable from `struct subsys_private`-sized kmalloc objects \u2014 yielding an arbitrary write and control-flow hijack primitive, i.e. full local privilege escalation.\nA:H - Even without successful exploitation the double free corrupts the slab allocator and panics the machine; on kernels built with CONFIG_SLAB_FREELIST_HARDENED the `BUG_ON(object == fp)` in `set_freepointer()` fires immediately, and `bus_release()` additionally calls `lockdep_unregister_key()` on a never-registered key on the early error paths."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
