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 resolved by ip_route_output_flow() are not released or put before return. It may cause the refcount leak, so fix it.

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."
