{"id":"UBUNTU-CVE-2025-62799","details":"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, a heap buffer overflow exists in the Fast-DDS DATA_FRAG receive path. An un authenticated sender can transmit a single malformed RTPS DATA_FRAG packet where `fragmentSize` and `sampleSize` are craft ed to violate internal assumptions. Due to a 4-byte alignment step during fragment metadata initialization, the code write s past the end of the allocated payload buffer, causing immediate crash (DoS) and potentially enabling memory corruption ( RCE risk). Versions 3.4.1, 3.3.1, and 2.6.11 patch the issue.","modified":"2026-02-23T07:04:28.256637Z","published":"2026-02-03T20:15:00Z","upstream":["CVE-2025-62799"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-62799"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-62799"},{"type":"REPORT","url":"https://github.com/eProsima/Fast-DDS/commit/d6dd58f4ecd28cd1c3bc4ef0467be9110fa94659"}],"affected":[{"package":{"name":"fastdds","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/fastdds@2.5.0+ds-3ubuntu0.1~esm1?arch=source&distro=esm-apps/jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.0+ds-9","2.4.1+ds-1","2.5.0+ds-3","2.5.0+ds-3ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.5.0+ds-3ubuntu0.1~esm1","binary_name":"fastdds-tools"},{"binary_version":"2.5.0+ds-3ubuntu0.1~esm1","binary_name":"libfastrtps-dev"},{"binary_version":"2.5.0+ds-3ubuntu0.1~esm1","binary_name":"libfastrtps2.5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-62799.json"}},{"package":{"name":"fastdds","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/fastdds@2.11.2+ds-6.1build3?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.10.1+ds-3","2.11.2+ds-6","2.11.2+ds-6ubuntu1","2.11.2+ds-6.1build2","2.11.2+ds-6.1build3"],"ecosystem_specific":{"binaries":[{"binary_version":"2.11.2+ds-6.1build3","binary_name":"fastdds-tools"},{"binary_version":"2.11.2+ds-6.1build3","binary_name":"libfastrtps-dev"},{"binary_version":"2.11.2+ds-6.1build3","binary_name":"libfastrtps2.11t64"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-62799.json"}},{"package":{"name":"fastdds","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/fastdds@3.1.2+ds-1build1?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.2+ds-1","3.1.2+ds-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.1.2+ds-1build1","binary_name":"fastdds-tools"},{"binary_version":"3.1.2+ds-1build1","binary_name":"libfastdds-dev"},{"binary_version":"3.1.2+ds-1build1","binary_name":"libfastdds3.1"},{"binary_version":"3.1.2+ds-1build1","binary_name":"libfastrtps-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-62799.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
