About this tag
RDMA security discussions on WindowsForum.com focus on vulnerabilities in the Linux kernel's RDMA stack, particularly the mlx5 driver used with Mellanox/NVIDIA ConnectX adapters. Recent threads cover CVE-2024-26907, a fortify-source bounds check fix affecting system availability, and CVE-2025-21732, a race condition in the mlx5 RDMA code. Microsoft's Azure Linux attestation notes potential impact, but the vulnerabilities are Linux-specific. These threads are relevant for infrastructure teams managing high-performance networking and RDMA deployments, emphasizing the need for timely kernel patches to maintain security and availability.

    Microsoft’s brief advisory that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate — but it is a product‑scoped attestation, not a categorical statement that no other Microsoft product could include the same vulnerable RDMA/mlx5 code. Background /...
