Copyright © 2012 Red Hat, Inc. All rights reserved. Moderate 2026-05-01T00:00:00 kernel: net/mlx5: lag: Check for LAG device before creating debugfs 5.5 CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H CWE-824

A flaw was found in the Linux kernel's `net/mlx5` driver. An error in the `__mlx5_lag_dev_add_mdev()` function can lead to the creation of debugfs entries without a valid LAG (Link Aggregation Group) context. This exposes interfaces that rely on a valid pointer, potentially leading to a NULL pointer dereference if accessed. Such a dereference could result in a system crash, causing a denial of service (DoS).
