CVE-2026-43013 in Linux
요약
\~에 의해 MITRE • 2026. 05. 01.
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: lag: Check for LAG device before creating debugfs
__mlx5_lag_dev_add_mdev() may return 0 (success) even when an error occurs that is handled gracefully. Consequently, the initialization flow proceeds to call mlx5_ldev_add_debugfs() even when there is no valid LAG context.
mlx5_ldev_add_debugfs() blindly created the debugfs directory and attributes. This exposed interfaces (like the members file) that rely on a valid ldev pointer, leading to potential NULL pointer dereferences if accessed when ldev is NULL.
Add a check to verify that mlx5_lag_dev(dev) returns a valid pointer before attempting to create the debugfs entries.
