Application crash via malicious RTPS data submessage
Published Jun 17, 2026 · Updated Jun 17, 2026
Out-of-bounds read in RTI Connext Micro allows remote attackers to crash applications or expose limited data via malicious RTPS messages. The core libraries process a malicious data submessage by reading beyond its intended buffer; RTI has not disclosed the affected parser or missing bounds check. The flaw is reachable without authentication when specified security protections are absent, and its consequence is limited to a crash or small confidentiality loss.
