CVE-2025-23259Network attack vector

Information disclosure and interface denial via misordered completions

Published Sep 4, 2025 · Updated Sep 4, 2025

Race condition in NVIDIA DPDK and MLNX_DPDK affected releases allows guest OS users to disclose data and interrupt a network interface. The mlx5 PMD receive routines assume completion entries arrive in work-queue order and address the wrong receive work item when shared queues return them out of order. The condition requires a guest VM using a shared receive queue; disclosure is limited to network data, and availability impact is limited to the interface.
