Service interruption via uncontrolled resource consumption
Published Aug 5, 2026 · Updated Aug 5, 2026
Denial of service in HPE Integrated Lights-Out 6 before 1.78 allows remote attackers to interrupt service via adjacent networks. HPE has not published the affected component, triggering input, or operation that causes the resource consumption. Exploitation requires unauthenticated access from an adjacent network and can make the management service unavailable, without reported data disclosure or modification.
