The 6LoWPAN implementation in Contiki-NG may cast a UDP header structure at a certain offset in a packet buffer. The code does not check whether the packet buffer is large enough to fit a full UDP header structure from the offset where the casting is made. Hence, it is possible to cause an out-of-bounds read beyond the packet buffer. The problem affects anyone running devices with Contiki-NG versions previous to 4.8, and which may receive 6LoWPAN packets from external parties. The problem has been patched in Contiki-NG version 4.8."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-125"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2022-36052", "ASSIGNER": "security-advisories@github.com"}}, "impact": {"baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 8.8, "attackVector": "NETWORK", "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "integrityImpact": "HIGH", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "HIGH"}, "impactScore": 5.9, "exploitabilityScore": 2.8}}, "publishedDate": "2022-09-01T12:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:contiki-ng:contiki-ng:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "4.8"}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2022-09-07T17:09Z"}
