{"apiVersion":"1.0","identifier":"CVE-2026-74238","description":"TIER IV Nebula through 1.2.0 contains an out-of-bounds read vulnerability in the Vlp32Decoder::unpack() function that allows unauthenticated remote attackers to cause the decoder to read past the end of a received UDP buffer into adjacent heap memory by sending a short UDP datagram. 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.","publishedAt":"2026-08-17T19:16:42","lastModifiedAt":"2026-08-20T16:17:59","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74238","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","epssProbability":0.00375,"riskScore":0.78,"affectedProduct":"TIER IV Nebula","affectedVersions":"<=1.2.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74238","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74238","en":"https://www.redsauce.net/en/cves/CVE-2026-74238","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74238","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74238","de":"https://www.redsauce.net/de/cves/CVE-2026-74238","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74238","el":"https://www.redsauce.net/el/cves/CVE-2026-74238"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74238"}}
