CVE-2026-22885Network attack vector

Memory disclosure via crafted IP-852 messages

Published Feb 20, 2026 · Updated Feb 20, 2026

Out-of-bounds read in EnOcean SmartServer IoT 4.60.009 and earlier allows remote attackers to disclose memory via crafted IP-852 messages. LON IP-852 management-message processing reads beyond the intended buffer when parsing a specially crafted message, exposing data from program memory. No authentication or user interaction is required, but high attack complexity limits practical exploitation and the reported effect is memory disclosure only.
