Overview

CVE-2026-43231 is a medium-severity vulnerability. It was published on May 6, 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:

media: radio-keene: fix memory leak in error path

Fix a memory leak in usb_keene_probe(). The v4l2 control handler is

initialized and controls are added, but if v4l2_device_register() or

video_register_device() fails afterward, the handler was never freed,

leaking memory.

Add v4l2_ctrl_handler_free() call in the err_v4l2 error path to ensure

the control handler is properly freed for all error paths after it is

initialized.

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.
