No remote peer data influences the path.\nAC:L - The attacker deterministically drives the code path by creating raw-packet QPs (including RSS QPs with a 64-entry indirection table, allocating many HW CQs per call), and the missing check fires on any device/host-returned cq_id outside [0, max_num_cqs) \u2014 including the INVALID_QUEUE_ID sentinel the sibling remove helper explicitly guards against; on a confidential/untrusted-host Azure VM the id is fully attacker-chosen.\nPR:L - An unprivileged local user with access to the RDMA uverbs device node and CAP_NET_RAW \u2014 routinely granted to non-root RDMA/HPC workloads and included in default container capability sets \u2014 can trigger it; consistent with the existing scoring of the identical mana_ib_create_qp_rss/install_cq_cb path (CVE-2026-46117, CVE-2026-46145).\nUI:N - Exploitation is entirely self-contained in the attacker\u0027s own QP-creation sequence; no victim action, mount, or file open is required.\nS:U - The out-of-bounds access corrupts kernel memory within the same kernel security authority; there is no hypervisor, IOMMU, or sandbox boundary crossed.\nC:H - `WARN_ON(gc-\u003ecq_table[cq-\u003equeue.id])` performs an unbounded out-of-bounds read past the vcalloc\u0027d table, and the resulting kernel-memory corruption is leverageable for arbitrary kernel read, disclosing sensitive data and defeating KASLR.\nI:H - `gc-\u003ecq_table[cq-\u003equeue.id] = gdma_cq` is an out-of-bounds write of a valid kernel heap pointer at an unvalidated index, and the stale entry is never cleared on teardown (remove_cq_cb bails on its bound check), giving a persistent write primitive usable for control-flow hijack and privilege escalation.\nA:H - An index beyond the table lands in unmapped vmalloc guard pages or corrupts adjacent kernel structures, producing an oops/panic; the completion path later dereferences cq_table entries, so a corrupted entry crashes the kernel."
