Severity ?
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/iwcm: Fix a use-after-free related to destroying CM IDs iw_conn_req_handler() associates a new struct rdma_id_private (conn_id) with an existing struct iw_cm_id (cm_id) as follows: conn_id->cm_id.iw = cm_id; cm_id->context = conn_id; cm_id->cm_handler = cma_iw_handler; rdma_destroy_id() frees both the cm_id and the struct rdma_id_private. Make sure that cm_work_handler() does not trigger a use-after-free by only freeing of the struct rdma_id_private after all pending work has finished.

Network-facing RDMA targets over iWARP (nvmet-rdma, NFS/RDMA svcrdma, iSER, SMB Direct, on cxgb4/irdma/qedr or software siw) drive both the event delivery and the `rdma_destroy_id()` teardown from remote peer actions.\nAC:L - The attacker controls both sides of the race: the connect/abort lifecycle of their own connection generates the queued CM events, and forcing a connection rejection or resetting the TCP connection drives the concurrent `rdma_destroy_id()`. The sequence can be repeated in a tight loop across many concurrent connections until the window is hit, with no condition outside attacker influence.\nPR:N - The RDMA-CM/iWARP handshake and the entire connect-reject-disconnect cycle complete before any upper-layer authentication (NVMe-oF Connect/in-band auth, RPCSEC, SMB session setup), so an unauthenticated peer that can reach the target port suffices. The local variant is even weaker-gated: rdma_ucm\u0027s `/dev/infiniband/rdma_cm` handlers contain no capability checks at all.\nUI:N - Exploitation is entirely driven by the attacker\u0027s own connection attempts and teardowns against an already-listening RDMA service. No action by any local user or administrator is required.\nS:U - The use-after-free corrupts kernel heap memory and hijacks kernel control flow within the same security authority as the vulnerable component. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - After the free, `cma_iw_handler()` reads `id_priv-\u003estate`, `id_priv-\u003ecm_id`, and other fields from the reallocated slab object, and the resulting control-flow hijack via the stale `event_handler` pointer can be leveraged for arbitrary kernel memory disclosure. Per kernel guidance a use-after-free is scored High for confidentiality.\nI:H - `cma_cm_event_handler()` performs an indirect call through `id_priv-\u003eid.event_handler` read from the freed object, and `mutex_lock(\u0026id_priv-\u003ehandler_mutex)` writes into it \u2014 together giving heap-spray-based arbitrary write and code-execution potential. This is a full control-flow hijack primitive, not a bounded corruption.\nA:H - Even without successful grooming, dereferencing the freed `rdma_id_private` (mutex operations and an indirect call on garbage) reliably oopses or panics the kernel, as observed by KASAN slab-use-after-free reports during blktests. The trigger is repeatable, so a remote attacker can crash the target at will."
