Overview

CVE-2026-43302 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:

drm/v3d: Set DMA segment size to avoid debug warnings

When using V3D rendering with CONFIG_DMA_API_DEBUG enabled, the

kernel occasionally reports a segment size mismatch. This is because

'max_seg_size' is not set. The kernel defaults to 64K. setting

'max_seg_size' to the maximum will prevent 'debug_dma_map_sg()'

from complaining about the over-mapping of the V3D segment length.

DMA-API: v3d 1002000000.v3d: mapping sg segment longer than device

claims to support [len=8290304] [max=65536]

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.

How can CyberStrike help with CVE-2026-43302?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-43302 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
