Summary

CVE-2025-64098 is a low-severity Out-of-bounds Read (CWE-125) vulnerability in Eprosima Fast Dds. Its CVSS base score is 1.7 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 36th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-5 (Denial-of-service Protection) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data

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 an Out-Of-Memory (OOM) condition, resulting in remote termination of Fast-DDS. If t he fields of `PID_IDENTITY_TOKEN` or `PID_PERMISSIONS_TOKEN` in the DATA Submessage are tampered with — specifically by ta mpering with the the `vecsize` value read by `readOctetVector` — a 32-bit integer overflow can occur, causing `std::vector ::resize` to request an attacker-controlled size and quickly trigger OOM and remote process termination. Versions 3.4.1, 3 .3.1, and 2.6.11 patch the issue.

MITRE ATT&CK Enterprise TechniquesAI

T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

The vulnerability allows remote attackers to trigger an out-of-memory condition via a crafted SPDP DATA submessage, leading to remote process termination. This maps to T1499.004 (Endpoint Denial of Service: Application or System Exploitation) as the flaw is exploited to exhaust resources and crash the target service.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces validation of untrusted DATA submessage fields (vecsize in PID_IDENTITY_TOKEN/PERMISSIONS_TOKEN) before any resize or allocation occurs.

prevent

Limits resource exhaustion from the resulting oversized std::vector allocation, preventing remote OOM termination of the Fast DDS process.

preventdetect

Verifies integrity of incoming SPDP packets and security tokens, detecting tampering that triggers the integer overflow before processing.

detects

Security testing in development and acceptance includes fuzzing and static analysis that detect out-of-bounds read defects before release.

A.8.15 Logging partial match
detects

Logging can record evidence of an out-of-bounds read but does not prevent the weakness itself.

prevents

Secure development life cycle mandates input validation and bounds checking that directly prevent out-of-bounds reads.

prevents

Application security requirements include explicit bounds and memory-safety specifications that mitigate buffer over-reads.

prevents

Secure system architecture and engineering principles require memory-safe design patterns and runtime protections against out-of-bounds access.

prevents

Secure coding standards explicitly forbid unsafe pointer arithmetic and mandate bounds-checked reads, eliminating CWE-125.
