{"id":"CVE-2023-50927","summary":"Insufficient boundary checks for DIO and DAO messages in RPL-Lite in Contiki-NG","details":"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.","aliases":["GHSA-9423-rgj4-wjfw"],"modified":"2026-04-10T05:05:42.282791Z","published":"2024-02-14T19:22:05.243Z","database_specific":{"cwe_ids":["CWE-125"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/50xxx/CVE-2023-50927.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/50xxx/CVE-2023-50927.json"},{"type":"ADVISORY","url":"https://github.com/contiki-ng/contiki-ng/security/advisories/GHSA-9423-rgj4-wjfw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-50927"},{"type":"FIX","url":"https://github.com/contiki-ng/contiki-ng/pull/2484"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/contiki-ng/contiki-ng","events":[{"introduced":"0"},{"fixed":"c20b12cd2db707d6c07918f8b26cfeb52cf298ca"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"4.9"}]}}],"versions":["2.0","2.1","2.2","2.2.1","2.2.2","2.2.3","2.3","2.4","2.5-release","2.6","2.6-rc0","develop/v3.x-fork","develop/v4.0","fork","old/v2.0","old/v2.1","old/v2.2","old/v2.2.1","old/v2.2.2","old/v2.2.3","old/v2.3","old/v2.4","old/v2.6","release/v4.0","release/v4.1","release/v4.2","release/v4.3","release/v4.4","release/v4.5","release/v4.6","release/v4.7","release/v4.8"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-50927.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H"}]}
