CVE-2026-68417Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: publish QP after initialization siw_create_qp() currently calls siw_qp_add() before the queues, CQ pointers, state, completion, and device list entry are ready. A QPN lookup can therefore reach a QP that is still being constructed. The `siw_create_qp()` function prematurely publishes a Queue Pair (QP) before its complete initialization. This allows a Queue Pair Number (QPN) lookup to access a QP that is still under construction, potentially leading to unexpected behavior or system instability. This issue affects RDMA siw (Soft-iWARP). QP published to lookup table before initialization completes. Systems not using siw RDMA are not affected. Red Hat severity: Moderate — CVSS 5.5…
