Overview

CVE-2026-43146 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: iris: Add buffer to list only after successful allocation

Move `list_add_tail()` to after `dma_alloc_attrs()` succeeds when creating

internal buffers. Previously, the buffer was enqueued in `buffers->list`

before the DMA allocation. If the allocation failed, the function returned

`-ENOMEM` while leaving a partially initialized buffer in the list, which

could lead to inconsistent state and potential leaks.

By adding the buffer to the list only after `dma_alloc_attrs()` succeeds,

we ensure the list contains only valid, fully initialized buffers.

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.
