Overview

CVE-2026-43142 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: gen1: Destroy internal buffers after FW releases

After the firmware releases internal buffers, the driver was not

destroying them. This left stale allocations that were no longer used,

especially across resolution changes where new buffers are allocated per

the updated requirements. As a result, memory was wasted until session

close.

Destroy internal buffers once the release response is received from the

firmware.

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.
