Overview

CVE-2024-35961 is a medium-severity vulnerability affecting linux linux_kernel. It was published on May 20, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5: Register devlink first under devlink lock

In case device is having a non fatal FW error during probe, the

driver will report the error to user via devlink. This will trigger

a WARN_ON, since mlx5 is calling devlink_register() last.

In order to avoid the WARN_ON[1], change mlx5 to invoke devl_register()

first under devlink lock.
