Overview

CVE-2026-72067 is a high-severity vulnerability. It was published on August 15, 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:

cpu: hotplug: Preserve per instance callback errors

cpuhp_invoke_callback() unwinds earlier callbacks for the same

hotplug state when one instance fails. The rollback path currently

reuses ret, so a successful rollback can hide the original error and

make the failed transition look successful.

Keep the rollback result separate from the original error.

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.
