CVE-2026-12554

Local privilege escalation via unmaintained component

Published Aug 24, 2026 · Updated Aug 27, 2026

Use of an unmaintained component in HP Easy Start before 2.16.7.260722 allows local users to escalate privileges on macOS systems. HP identifies only an unmaintained third-party component and has not disclosed its name, vulnerable operation, or the input that reaches it. Exploitation requires existing low-privileged local access and no user interaction; successful escalation permits reading or changing data and interrupting the system.
