2DescriptionGitHub Advisory
Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group ). Prior to versions 3.4.1, 3.3.1, and 2.6.11, when the security mode is enabled, modifying the DATA Submessage within an SPDP packet sent by a publisher causes a heap buffer overflow, resulting in remote termination of Fast-DDS. If the fields of PID_IDENTITY_TOKEN or PID_PERMISSIONS_TOKEN in the DATA Submessage - specifically by tampering with the str_size value read by readString (called from readBinaryProperty) - are modified, a 32-bit integer overflow can occur, causing std::vector::resize to use an attacker-controlled size and quickly trigger heap buffer overflow and remote process term ination. Versions 3.4.1, 3.3.1, and 2.6.11 patch the issue.
Executive ViewAI
CVE-2025-62601 is a high-severity vulnerability affecting Fast DDS, a middleware component used in distributed systems and real-time data applications. Organizations using Fast DDS in production environments face potential service disruption or unauthorized access risks and should prioritize patching to maintain operational continuity and data integrity.
Apply vendor patch.

SSVC AssessmentENISA
Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Integer overflow occurs when an arithmetic operation produces a result that exceeds the maximum value a given integer type can store.
