Overview

CVE-2026-46288 is a high-severity vulnerability. It was published on June 8, 2026 and has a CVSS 3.1 base score of 8.4 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.4, rated HIGH. 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:

of: unittest: fix use-after-free in of_unittest_changeset()

The variable 'parent' is assigned the value of 'nchangeset' earlier in the

function, meaning both point to the same struct device_node. The call to

of_node_put(nchangeset) can decrement the reference count to zero and

free the node if there are no other holders. After that, the code still

uses 'parent' to check for the presence of a property and to read a

string property, leading to a use-after-free.

Fix this by moving the of_node_put() call after the last access to

'parent', avoiding the UAF.

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.
