The attacker selects which local address, and therefore which `bound_dev_if`, the connection lands on.\nAC:L - No race, no memory-layout dependency and no timing window \u2014 the missing `rdma_put_gid_attr()` is hit deterministically whenever the GID entry\u0027s netdev ifindex or netns differs from the id\u0027s, and the attacker simply repeats connection attempts (or `bind()` calls locally).\nPR:N - `iw_conn_req_handler()` runs during MPA connect-request processing, before any ULP-level authentication or credential check. On the local path `ucma.c` contains no `capable()` check at all and `/dev/infiniband/rdma_cm` is mode 0666 under stock rdma-core udev rules.\nUI:N - The leak occurs entirely within kernel connection-establishment or bind handling; no action by any local user or administrator is needed.\nS:U - The leaked reference, the orphaned GID entry and the pinned netdevice all live in the same kernel security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:N - A dropped `kref_put()` neither reads out-of-bounds nor exposes freed or uninitialized memory to the attacker, and no kernel address or data is returned on the error path.\nI:N - Nothing is written out of bounds or type-confused; `kref` is built on `refcount_t`, which saturates instead of wrapping, so the inflated count cannot be driven into a premature free or write primitive.\nA:H - The orphaned GID entry permanently retains its `dev_hold()`, so `unregister_netdevice()` loops forever (\"waiting for X to become free\") and wedges the global single-threaded `cleanup_net` workqueue, blocking all subsequent netns teardown. `release_gid_table()` also emits a `WARN_ONCE` GID-ref-leak splat, which is a panic on `panic_on_warn` systems."

Detection rules are retrieved from Rulezet.

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.
