Overview

CVE-2022-48688 is a medium-severity vulnerability. It was published on May 3, 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:

i40e: Fix kernel crash during module removal

The driver incorrectly frees client instance and subsequent

i40e module removal leads to kernel crash.

Reproducer:

1. Do ethtool offline test followed immediately by another one

host# ethtool -t eth0 offline; ethtool -t eth0 offline

2. Remove recursively irdma module that also removes i40e module

host# modprobe -r irdma

Result:

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
