Overview

CVE-2024-26652 is a medium-severity vulnerability. It was published on March 27, 2024 and has a CVSS 3.1 base score of 4.1 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.1, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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

net: pds_core: Fix possible double free in error handling path

When auxiliary_device_add() returns error and then calls

auxiliary_device_uninit(), Callback function pdsc_auxbus_dev_release

calls kfree(padev) to free memory. We shouldn't call kfree(padev)

again in the error handling path.

Fix this by cleaning up the redundant kfree() and putting

the error handling back to where the errors happened.

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.
