rdma stability

About this tag
The rdma stability tag on WindowsForum.com covers discussions and fixes related to the stability of Remote Direct Memory Access (RDMA) implementations, particularly in Linux kernel drivers. A highlighted thread addresses CVE-2025-68209, a vulnerability in the Mellanox/NVIDIA mlx5 driver that could cause kernel null-pointer faults due to unsafe default values in Completion Queues (CQs). This fix restores kernel stability by preventing spurious triggers of polling-only kernel CQs. The tag focuses on kernel-level RDMA stability issues, driver patches, and hardware-specific concerns for RDMA adapters.

  1. CVE-2025-68209: mlx5 CQ Default Init Fix Restores Kernel Stability

    A small, surgical kernel fix published in mid‑December closes a subtle yet real stability hole in the Mellanox/NVIDIA mlx5 driver: CVE‑2025‑68209 corrects unsafe default values used when creating Completion Queues (CQs), preventing a rare path where a polling‑only kernel CQ could be spuriously...
