Overview

CVE-2026-46269 is a medium-severity vulnerability. It was published on June 3, 2026 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:

pinctrl: canaan: k230: Fix NULL pointer dereference when parsing devicetree

When probing the k230 pinctrl driver, the kernel triggers a NULL pointer

dereference. The crash trace showed:

[ 0.732084] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000068

[ 0.740737] ...

[ 0.776296] epc : k230_pinctrl_probe+0x1be/0x4fc

In k230_pinctrl_parse_functions(), we attempt to retrieve the device

pointer via info->pctl_dev->dev, but info->pctl_dev is only initialized

after k230_pinctrl_parse_dt() completes.

At the time of DT parsing, info->pctl_dev is still NULL, leading to

the invalid dereference of info->pctl_dev->dev.

Use the already available device pointer from platform_device

instead of accessing through uninitialized pctl_dev.

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.
