Overview

CVE-2022-49725 is a high-severity vulnerability. It was published on February 26, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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 call trace in setup_tx_descriptors

After PF reset and ethtool -t there was call trace in dmesg

sometimes leading to panic. When there was some time, around 5

seconds, between reset and test there were no errors.

Problem was that pf reset calls i40e_vsi_close in prep_for_reset

and ethtool -t calls i40e_vsi_close in diag_test. If there was not

enough time between those commands the second i40e_vsi_close starts

before previous i40e_vsi_close was done which leads to crash.

Add check to diag_test if pf is in reset and don't start offline

tests if it is true.

Add netif_info("testing failed") into unhappy path of i40e_diag_test()

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.
