Attackers can send a malformed datagram to the Velodyne UDP sensor port, which lacks sender-address restrictions present in other drivers, causing fabricated points derived from heap memory contents to be silently published into downstream PointCloud2 messages consumed by Autoware nodes.","published":"2026-08-17T19:16:42.713","modified":"2026-08-17T19:16:42.713","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/tier4/nebula/issues/488"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/tier-iv-nebula-heap-out-of-bounds-read-via-vlp32-udp-decoder"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-17T19:16:42.713"}}
