CVE-2025-62601
7.5 · HIGHOverview
CVE-2025-62601 is a high-severity vulnerability affecting eprosima fast_dds. It was published on February 3, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from eprosima. Update fast_dds to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
