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."}],"source":{"advisory":"GHSA-9423-rgj4-wjfw","discovery":"UNKNOWN"}},"adp":[{"affected":[{"vendor":"contiki-ng","product":"contiki-ng","cpes":["cpe:2.3:o:contiki-ng:contiki-ng:4.9:*:*:*:*:*:*:*"],"defaultStatus":"unknown","versions":[{"version":"0","status":"affected","lessThan":"4.9","versionType":"custom"}]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-02-15T16:42:01.347508Z","id":"CVE-2023-50927","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-04-24T15:15:35.777Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T22:23:43.859Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/contiki-ng/contiki-ng/security/advisories/GHSA-9423-rgj4-wjfw","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/contiki-ng/contiki-ng/security/advisories/GHSA-9423-rgj4-wjfw"},{"name":"https://github.com/contiki-ng/contiki-ng/pull/2484","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/contiki-ng/contiki-ng/pull/2484"}]}]}}
