Overview

CVE-2026-80608 is a high-severity vulnerability. It was published on August 28, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, 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/amdxdna: Fix iommu domain lifetime race during device removal

When force_iova mode is enabled, amdxdna_remove() frees xdna->domain. If

amdxdna_gem_obj_free() is called after device removal, it may attempt to

access xdna->domain, resulting in a use-after-free.

Fix the race by adding freeing xdna->domain as a managed release action,

so its lifetime is managed by DRM and remains valid until all managed

resources are released.

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.
