mlx5 driver

About this tag
The mlx5 driver is the upstream Linux kernel driver for Mellanox/NVIDIA ConnectX and BlueField adapters, widely used in high-performance networking and enterprise data centers. Discussions on WindowsForum.com cover several CVEs affecting this driver, including CVE-2025-38109, a use-after-free during shutdown in the ECVF vport teardown, which Microsoft's advisory confirms affects Azure Linux. CVE-2024-26907 addresses a fortify-source warning in RDMA mlx5 code, impacting availability for systems using Mellanox/NVIDIA adapters. CVE-2025-68209 fixes unsafe default values in Completion Queue creation, preventing kernel null-pointer faults. These threads highlight the driver's critical role in network stability and security, with patches that infrastructure teams should prioritize.
