A malicious user can pass a tensor of a different rank, triggering a `CHECK` assertion failure and a crash. Where users can control the components of the input sparse tensor, this enables denial of service in serving installations.","solution":"The issue is patched in commit 3cbb917b4714766030b28eba9fb41bb97ce9ee02 and released in TensorFlow version 2.3.1.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2020-15197","publishedAt":"2020-09-25T23:15:14.963Z","cveId":"CVE-2020-15197","cweIds":["CWE-20","CWE-617"],"cvssScore":"6.3","cvssSeverity":"medium","severity":"medium","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":["tensorflow@= 2.3.0 (fixed: 2.3.1)","tensorflow-cpu@= 2.3.0 (fixed: 2.3.1)","tensorflow-gpu@= 2.3.0 (fixed: 2.3.1)"],"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 SparseCountSparseOutput crash from unvalidated sparse tensor input","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00726,"epssCheckedAt":"2026-11-04T12:08:33.690Z","kevDateAdded":null,"advisoryAliases":["GHSA-qc53-44cj-vfvx"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T04:01:02.885Z","patchAvailable":true,"disclosureDate":null,"fixReleasedAt":"2020-09-24T19:23:11.978Z","daysToFix":-1,"fixCheckedAt":"2026-10-29T21:52:48.105Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["availability"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"tensorflow-cpu","fixedVersion":"2.3.1","matchedVersion":"2.3.1","fixReleasedAt":"2020-09-24T19:29:12.073Z","daysToFix":-1,"match":"ecosystem","source":"registry","status":"found","checkedAt":"2026-10-29T21:52:47.953Z"},{"ecosystem":"pypi","name":"tensorflow-gpu","fixedVersion":"2.3.1","matchedVersion":"2.3.1","fixReleasedAt":"2020-09-24T19:32:56.435Z","daysToFix":-1,"match":"ecosystem","source":"registry","status":"found","checkedAt":"2026-10-29T21:52:47.953Z"},{"ecosystem":"pypi","name":"tensorflow","fixedVersion":"2.3.1","matchedVersion":"2.3.1","fixReleasedAt":"2020-09-24T19:23:11.978Z","daysToFix":-1,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:52:47.953Z"}]}}
