Remote process termination via wrapped property length
Published Feb 3, 2026 · Updated Feb 3, 2026
Denial of service in eProsima Fast DDS 3.4.0 and earlier allows remote attackers to terminate processes through a crafted SPDP packet. readPropertySeq multiplies an attacker-controlled token length by 16 in 32-bit arithmetic; wraparound bypasses the size check, and properties.resize requests an excessive allocation. Exploitation requires DDS Security and receipt of the malicious discovery DATA submessage; the bounded consequence is OOM process termination, not data access or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <2.6.11
- Affected versionversion=3.0.0 <3.3.1
- Affected versionversion=3.4.0 <3.4.1
