In affected versions, the async implementation of `CollectiveReduceV2` has a memory leak and a use after free, caused by asynchronous computation and by accessing objects after they have been `std::move()`d from. The weakness is classified as CWE-416.","solution":"The fix will be included in TensorFlow 2.7.0, and the commit will also be cherrypicked onto TensorFlow 2.6.1, the only other affected version.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2021-41220","publishedAt":"2021-11-06T03:15:08.350Z","cveId":"CVE-2021-41220","cweIds":["CWE-416"],"cvssScore":"7.8","cvssSeverity":"high","severity":"high","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":["tensorflow@= 2.6.0 (fixed: 2.6.1)","tensorflow-cpu@= 2.6.0 (fixed: 2.6.1)","tensorflow-gpu@= 2.6.0 (fixed: 2.6.1)"],"affectedPackageNames":["tensorflow","tensorflow-cpu","tensorflow-gpu"],"affectedPackageRefs":["pypi:tensorflow","pypi:tensorflow-cpu","pypi:tensorflow-gpu"],"affectedVendors":["Google"],"affectedVendorsRaw":["TensorFlow"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"TensorFlow memory leak and use after free in async CollectiveReduceV2","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00211,"epssCheckedAt":"2026-11-04T18:09:12.971Z","kevDateAdded":null,"advisoryAliases":["GHSA-gpfh-jvf9-7wg5"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:59:00.790Z","patchAvailable":true,"disclosureDate":null,"fixReleasedAt":"2021-11-01T20:30:07.568Z","daysToFix":-5,"fixCheckedAt":"2026-10-29T21:49:50.222Z","capecIds":["CAPEC-233"],"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","availability"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"tensorflow-cpu","fixedVersion":"2.6.1","matchedVersion":"2.6.1","fixReleasedAt":"2021-11-01T20:42:57.767Z","daysToFix":-5,"match":"ecosystem","source":"registry","status":"found","checkedAt":"2026-10-29T21:49:50.071Z"},{"ecosystem":"pypi","name":"tensorflow-gpu","fixedVersion":"2.6.1","matchedVersion":"2.6.1","fixReleasedAt":"2021-11-01T20:55:41.969Z","daysToFix":-5,"match":"ecosystem","source":"registry","status":"found","checkedAt":"2026-10-29T21:49:50.071Z"},{"ecosystem":"pypi","name":"tensorflow","fixedVersion":"2.6.1","matchedVersion":"2.6.1","fixReleasedAt":"2021-11-01T20:30:07.568Z","daysToFix":-5,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:49:50.071Z"}]}}
