CVE-2024-42398Network attack vector

Access-point disruption via Soft AP resource exhaustion

Published Aug 6, 2024 · Updated Mar 24, 2025

Denial of service in the Soft AP daemon in HPE ArubaOS and Aruba Instant allows remote attackers to interrupt access points via PAPI. Public records identify uncontrolled resource consumption in the daemon but do not disclose the malformed PAPI message or exhausted resource. The attack requires network access to PAPI, needs no authentication or user interaction, and disrupts normal operation without reported data exposure or modification.
