CVE-2024-44459Network attack vector

Unauthenticated broker crash via excessive memory allocation

Published Sep 12, 2024 · Updated Oct 30, 2024

Denial of service in Octavo Labs VerneMQ 2.0.1 allows remote attackers to crash the broker through excessive memory consumption. The public record identifies uncontrolled memory allocation but does not disclose the responsible code locus, MQTT operation, or crafted input because its sole proof reference is unavailable. No authentication or user interaction is required, and the reported consequence is loss of broker availability rather than data access or modification.
