{"id":"CVE-2023-50927","state":"PUBLISHED","title":"Insufficient boundary checks for DIO and DAO messages in RPL-Lite in Contiki-NG","description":"Contiki-NG is an open-source, cross-platform operating system for Next-Generation IoT devices. An attacker can trigger out-of-bounds reads in the RPL-Lite implementation of the RPL protocol in the Contiki-NG operating system. This vulnerability is caused by insufficient control of the lengths for DIO and DAO messages, in particular when they contain RPL sub-option headers. The problem has been patched in Contiki-NG 4.9. Users are advised to upgrade. Users unable to upgrade should manually apply the code changes in PR #2484.","publishedAt":"2024-02-14T19:22:05.243Z","updatedAt":"2025-04-24T15:15:35.777Z","severity":{"score":8.6,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["contiki-ng contiki-ng"],"affected":[{"vendor":"contiki-ng","product":"contiki-ng","versions":[{"version":"< 4.9","status":"affected"}]}],"references":["https://github.com/contiki-ng/contiki-ng/security/advisories/GHSA-9423-rgj4-wjfw","https://github.com/contiki-ng/contiki-ng/pull/2484"],"weaknesses":["CWE-125"],"ingestedAt":"2026-10-29T20:06:33.064Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/50xxx/CVE-2023-50927.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-50927","state":"PUBLISHED","datePublished":"2024-02-14T19:22:05.243Z","dateUpdated":"2025-04-24T15:15:35.777Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-12-15T20:57:23.174Z"},"containers":{"cna":{"title":"Insufficient boundary checks for DIO and DAO messages in RPL-Lite in Contiki-NG","descriptions":[{"lang":"en","value":"Contiki-NG is an open-source, cross-platform operating system for Next-Generation IoT devices.
