CVE-2026-72067
7.8
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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.
