Overview

CVE-2026-46201 is a high-severity vulnerability. It was published on May 28, 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:

drm/xe: Fix dma-buf attachment leak in xe_gem_prime_import()

When xe_dma_buf_init_obj() fails, the attachment from

dma_buf_dynamic_attach() is not detached. Add dma_buf_detach() before

returning the error. Note: we cannot use goto out_err here because

xe_dma_buf_init_obj() already frees bo on failure, and out_err would

double-free it.

(cherry picked from commit a828eb185aac41800df8eae4b60501ccc0dbbe51)

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.
