Overview

CVE-2026-43498 is a high-severity vulnerability. It was published on May 21, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:

accel/ivpu: Disallow re-exporting imported GEM objects

Prevent re-exporting of imported GEM buffers by adding a custom

prime_handle_to_fd callback that checks if the object is imported

and returns -EOPNOTSUPP if so.

Re-exporting imported GEM buffers causes loss of buffer flags settings,

leading to incorrect device access and data corruption.

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.
