Vulnerability from fkie_nvd - Published: 2026-09-17 17:17 - Updated: 2026-09-18 18:18

Severity

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Fix potential use after free in ib_free_cq() When accessing a CQ via the netlink path the only synchronization mechanism for the said CQ is rdma_restrack_get(). Currently, rdma_restrack_del() is invoked at the end of ib_free_cq(), which is too late, since by that point vendor-specific resources associated with the CQ might already be freed. This can leave a short window where the CQ remains accessible through restrack, leading to a potential use-after-free. Fix this by moving the rdma_restrack_del() call to be before the freeing of the vendor-specific resources ensuring that the CQ is removed from restrack before its internal resources are released. This guarantees that no new users hold references to a CQ that is in the process of destruction.

This can leave a short window where the CQ remains accessible\nthrough restrack, leading to a potential use-after-free.\n\nFix this by moving the rdma_restrack_del() call to be before the freeing\nof the vendor-specific resources ensuring that the CQ is removed from\nrestrack before its internal resources are released.\nThis guarantees that no new users hold references to a CQ that is in\nthe process of destruction."

No remote protocol message carries the lookup; the accessor is a netlink syscall.\nAC:L - The attacker drives both sides of the race: one thread loops RDMA_NLDEV_CMD_RES_CQ_GET while another opens and drops kernel-ULP RDMA connections so ib_free_cq() runs (svc_rdma_free() or smbdirect_connection_destroy_qp()). That is not a victim-only timing window.\nPR:L - RDMA_NLDEV_CMD_RES_CQ_GET in nldev_cb_table has no RDMA_NL_ADMIN_PERM, and NETLINK_RDMA is created with NL_CFG_F_NONROOT_RECV, so an ordinary user can dump CQs. Kernel CQ teardown via /dev/infiniband/rdma_cm (ucma_misc mode 0666) also does not need init-namespace root.\nUI:N - The attacker sends the RDMA_NLDEV_CMD_RES_CQ_GET dumps and tears down their own kernel-ULP RDMA connections; no other user must mount a volume, open a device, or confirm an action.\nS:U - The UAF is of host-kernel CQ vendor state (ib_cq buffers freed in destroy_cq/pre_destroy_cq) and stays inside the same kernel authority; it is not a VM escape, IOMMU bypass, or guest-to-host boundary cross.\nC:H - c4iw_destroy_cq() \u2192 destroy_cq() dma_free_coherent()s chp-\u003ecq.queue before rdma_restrack_del(); a concurrent fill_res_cq_entry \u2192 c4iw_fill_res_cq_entry still indexes that queue, so the UAF reads freed CQ-ring memory.\nI:H - The same ib_free_cq() window lets fill_res_cq_entry use vendor CQ resources already released by destroy_cq/pre_destroy_cq (Chelsio queue pages; mlx5 destroy_cq_kernel CQ buffers). Reclaiming that heap object yields an arbitrary write and control-flow hijack.\nA:H - fill_res_cq_entry walking a CQ whose queue or HW context was already freed in ib_free_cq() (after pre_destroy_cq/destroy_cq, before rdma_restrack_del) oopses or panics the kernel even without a crafted exploit."
