Overview

CVE-2022-49192 is a medium-severity vulnerability. It was published on February 26, 2025 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:

drivers: ethernet: cpsw: fix panic when interrupt coaleceing is set via ethtool

cpsw_ethtool_begin directly returns the result of pm_runtime_get_sync

when successful.

pm_runtime_get_sync returns -error code on failure and 0 on successful

resume but also 1 when the device is already active. So the common case

for cpsw_ethtool_begin is to return 1. That leads to inconsistent calls

to pm_runtime_put in the call-chain so that pm_runtime_put is called

one too many times and as result leaving the cpsw dev behind suspended.

The suspended cpsw dev leads to an access violation later on by

different parts of the cpsw driver.

Fix this by calling the return-friendly pm_runtime_resume_and_get

function.

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.
