{"cve":"CVE-2025-64098","nvd":{"published":"2026-02-03T20:15:57.127","modified":"2026-06-17T09:53:49.213","status":"Analyzed","description":"Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group\n). 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 \nSPDP packet sent by a publisher causes an Out-Of-Memory (OOM) condition, resulting in remote termination of Fast-DDS. If t\nhe fields of `PID_IDENTITY_TOKEN` or `PID_PERMISSIONS_TOKEN` in the DATA Submessage are tampered with — specifically by ta\nmpering with the the `vecsize` value read by `readOctetVector` — a 32-bit integer overflow can occur, causing `std::vector\n::resize` to request an attacker-controlled size and quickly trigger OOM and remote process termination. Versions 3.4.1, 3\n.3.1, and 2.6.11 patch the issue.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U","score":1.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9},"cwes":["CWE-125","CWE-190"],"references":["https://github.com/eProsima/Fast-DDS/commit/354218514d32beac963ff5c306f1cf159ee37c5f","https://github.com/eProsima/Fast-DDS/commit/a726e6a5daba660418d1f7c05b6f203c17747d2b","https://github.com/eProsima/Fast-DDS/commit/ced3b6f92d928af1eae77d5fe889878128ad421a","https://security-tracker.debian.org/tracker/CVE-2025-64098"],"products":["debian:debian_linux","eprosima:fast_dds"],"source":"nvd","synced_at":"2026-10-19T22:22:27.261130201+00:00"},"epss":{"cve":"CVE-2025-64098","score":0.00481,"percentile":0.41545,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
