Echo: linux: security update to 6.1.170-1

medium Tenable Cloud Security Plugin ID 465937

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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.
 (CVE-2026-43013)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
