An attacker who supplies a crafted SVM model, introduced via pickle, json, or another model persistence standard, with a large value in the _n_support array can cause a denial of service through a segmentation fault. The scikit-learn vendor states the behavior can only occur if an application violates the library's API by changing a private attribute, and the record is marked Disputed.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2020-28975","publishedAt":"2020-11-22T02:15:10.680Z","cveId":"CVE-2020-28975","cweIds":null,"cvssScore":"7.5","cvssSeverity":"high","severity":"high","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":["scikit-learn@>= 0.23.2, < 1.0.1 (fixed: 1.0.1)"],"affectedPackageNames":["scikit-learn"],"affectedPackageRefs":["pypi:scikit-learn"],"affectedVendors":[],"affectedVendorsRaw":["scikit-learn","Libsvm"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Libsvm svm_predict_values denial of service via crafted SVM model","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.035,"epssCheckedAt":"2026-11-04T18:09:12.821Z","kevDateAdded":null,"advisoryAliases":["GHSA-jxfp-4rvq-9h9m"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T04:00:51.791Z","patchAvailable":true,"disclosureDate":null,"fixReleasedAt":"2021-10-25T11:00:07.027Z","daysToFix":337,"fixCheckedAt":"2026-10-29T21:52:31.523Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["availability"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"scikit-learn","fixedVersion":"1.0.1","matchedVersion":"1.0.1","fixReleasedAt":"2021-10-25T11:00:07.027Z","daysToFix":337,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:52:31.372Z"}]}}
