Overview

CVE-2026-43312 is a medium-severity vulnerability. It was published on May 8, 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: i2c: ov5647: Initialize subdev before controls

In ov5647_init_controls() we call v4l2_get_subdevdata, but it is

initialized by v4l2_i2c_subdev_init() in the probe, which currently

happens after init_controls(). This can result in a segfault if the

error condition is hit, and we try to access i2c_client, so fix the

order.

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.
