This can be achieved by changing a buffer index in the flatbuffer serialization to convert a read-only tensor to a read-write one. The runtime assumes that these buffers are written to before a possible read, hence they are initialized with `nullptr`. However, by changing the buffer index for a tensor and implicitly converting that tensor to be a read-write one, as there is nothing in the model that writes to it, we get a null pointer dereference. The issue is patched in commit 0b5662bc, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-476"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2020-15209", "ASSIGNER": "security-advisories@github.com"}}, "impact": {"baseMetricV2": {"cvssV2": {"version": "2.0", "baseScore": 4.3, "accessVector": "NETWORK", "vectorString": "AV:N/AC:M/Au:N/C:N/I:N/A:P", "authentication": "NONE", "integrityImpact": "NONE", "accessComplexity": "MEDIUM", "availabilityImpact": "PARTIAL", "confidentialityImpact": "NONE"}, "severity": "MEDIUM", "acInsufInfo": false, "impactScore": 2.9, "obtainAllPrivilege": false, "exploitabilityScore": 8.6, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": false}, "baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 5.9, "attackVector": "NETWORK", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "HIGH", "availabilityImpact": "HIGH", "privilegesRequired": "NONE", "confidentialityImpact": "NONE"}, "impactScore": 3.6, "exploitabilityScore": 2.2}}, "publishedDate": "2020-09-25T19:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:google:tensorflow:*:*:*:*:lite:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "1.15.4"}, {"cpe23Uri": "cpe:2.3:a:google:tensorflow:*:*:*:*:lite:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.0.3", "versionStartIncluding": "2.0.0"}, {"cpe23Uri": "cpe:2.3:a:google:tensorflow:*:*:*:*:lite:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.1.2", "versionStartIncluding": "2.1.0"}, {"cpe23Uri": "cpe:2.3:a:google:tensorflow:*:*:*:*:lite:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.2.1", "versionStartIncluding": "2.2.0"}, {"cpe23Uri": "cpe:2.3:a:google:tensorflow:*:*:*:*:lite:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.3.1", "versionStartIncluding": "2.3.0"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:opensuse:leap:15.2:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2021-09-16T15:45Z"}
