Title
net/smc: fix neighbour and rtable leak in smc_ib_find_route()
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: fix neighbour and rtable leak in smc_ib_find_route()
In smc_ib_find_route(), the neighbour found by neigh_lookup() and rtable

"value": "AV:N - The leak is triggered while processing SMC CLC handshake messages received over TCP from a remote peer \u2014 the server path takes `daddr` straight from the peer\u0027s CLC Proposal v2 extension GID (`af_smc.c:2323`) and the client path from the peer\u0027s CLC Accept GID (`af_smc.c:1245`). No local access, and no RDMA fabric connectivity to the attacker is needed since the handshake is ordinary TCP.\nAC:L - The missing `neigh_release()`/`ip_rt_put()` is unconditional \u2014 every successful route resolution leaks, with no race to win and no memory-layout dependency, and the attacker fully controls `daddr` via the GID it advertises. In an SMC-Rv2 deployment (the scenario in which this code runs at all) the attacker just opens TCP connections in a loop to accumulate leaked references.\nPR:N - `smc_listen_work()` processes the CLC Proposal immediately after TCP accept, before any credential check exists \u2014 SMC has no authentication, and the UEID compared in `smc_clc_match_eid()` is a cleartext fabric identifier the client itself broadcasts in its proposal, not a secret. The client-side path via `smc_connect_rdma_v2_prepare()` requires no EID from the attacker at all.\nUI:N - The attacker initiates the TCP connection to a victim SMC listener and drives the entire handshake itself; the listen worker runs asynchronously with no action by any local user.\nS:U - The leaked `rtable`, `neighbour` and pinned `net_device` references all remain within the kernel\u0027s own resource domain, and no VM/host, IOMMU, or sandbox boundary is crossed.\nC:N - Only reference counts are leaked \u2014 no freed or out-of-bounds memory is read, and nothing from kernel memory is copied back to the peer or to userspace. `nexthop_mac` is filled from a validly-held neighbour before the leak occurs.\nI:N - The bug is a missing decrement, which is the safe direction \u2014 no object is freed early, so there is no UAF, write primitive, or control-flow impact, and both `rcuref` (dst) and `refcount_t` (neigh) saturate with a warning rather than wrapping to zero.\nA:H - Each leaked `dst` and `neighbour` permanently pins a `net_device` reference (`netdev_hold()` in `dst_init()`/`neigh_alloc()`), so device unregistration and network-namespace teardown hang forever in the `unregister_netdevice: waiting for %s to become free` loop, blocking the global `cleanup_net` worker. Additionally, `neigh_forced_gc()` skips any entry with refcount \u003e 1, so an unauthenticated peer varying its advertised GID mints unreclaimable ARP entries until `gc_thresh3` overflow breaks all neighbour resolution on the host, alongside unbounded kernel memory growth."

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.
