CVE-2025-62599
Memory Safety in Eprosima Fast Dds ≤ 2.6.11
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:HSummary
CVE-2025-62599 is a high-severity Integer Overflow or Wraparound (CWE-190) vulnerability in Eprosima Fast Dds. Its CVSS base score is 8.6 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked at the 29th 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 SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
eProsima Fast DDS, a C++ implementation of the OMG Data Distribution Service (DDS) standard, is affected by CVE-2025-62599 in versions prior to 2.6.11, 2.14.6, 3.2.4, 3.3.1, and 3.4.1. The vulnerability stems from an integer overflow (CWE-190) and uncontrolled memory allocation (CWE-789) when security mode is enabled. Specifically, modifying the DATA Submessage within an SPDP packet sent by a publisher—by tampering with the length field in the readPropertySeq of PID_IDENTITY_TOKEN or PID_PERMISSION_TOKEN—triggers an out-of-memory (OOM) condition during a resize operation, resulting in remote termination of the Fast DDS process. The issue carries a CVSS v3.1 base score of 8.6 (AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H).
Any unauthenticated network attacker can exploit this vulnerability with low attack complexity and no user interaction. By crafting and sending a malformed SPDP packet to a vulnerable Fast DDS instance operating in security mode, the attacker induces the integer overflow, leading to excessive memory allocation and subsequent process crash, achieving a denial-of-service (DoS) on availability with a changed scope that may impact dependent components or systems.
The eProsima Fast DDS security advisory (https://github.com/eProsima/Fast-DDS/security/advisories/GHSA-fc3f-wcj5-5cph) confirms the vulnerability and states that it is addressed in versions 2.6.11, 2.14.6, 3.2.4, 3.3.1, and 3.4.1. Mitigation requires upgrading to one of these patched releases, as no other workarounds are specified.

Vulnerability Data
eprosima Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group). Prior to 2.6.11, 2.14.6, 3.2.4, 3.3.1, and 3.4.1, when the security mode is enabled, modifying the DATA Submessage within an…
more
SPDP packet sent by a publisher causes an Out-Of-Memory (OOM) condition, resulting in remote termination of Fast-DDS. If the fields of PID_IDENTITY_TOKEN or PID_PERMISSION_TOKEN in the DATA Submessage — specifically by tampering with the length field in readPropertySeq — are modified, an integer overflow occurs, leading to an OOM during the resize operation. This vulnerability is fixed in 2.6.11, 2.14.6, 3.2.4, 3.3.1, and 3.4.1.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation (static analysis, fuzzing, unit tests) directly finds integer overflow defects before deployment.
Input validation directly rejects or bounds untrusted size values before any allocation occurs.
Secure engineering principles require use of safe arithmetic constructs or language features that structurally eliminate integer overflow during calculation.
Resource quotas and priority allocation limit the system-wide impact of an oversized request.

Security testing in development can detect integer overflows before release.
Secure SDLC mandates input validation and arithmetic checks that prevent integer overflows.
Application security requirements include bounds checking and safe arithmetic to avoid overflow conditions.
Secure architecture principles require defensive coding patterns that mitigate integer wraparound risks.
Secure coding standards explicitly forbid unsafe integer operations and mandate overflow-safe constructs.
Capacity management monitors overall resource use but does not prevent individual allocation bugs.
