{"data":{"id":"8be3fc8d-a890-4db8-9575-b010c12654c2","title":"Model Lineage Analysis: Determination and Closeness Measurement","summary":"This paper reformulates model lineage determination as a question of whether two models' parameters lie within the same local optimum of the loss landscape. The authors propose a method for lineage determination and a task-agnostic, modification-type-agnostic way to measure lineage closeness, based on the mean adversarial distance from data points to decision boundaries and the matching rate of predictions. Experiments report 100% accuracy in lineage determination across a wide range of modification scenarios.","solution":"N/A -- no mitigation discussed in source.","labels":["research","security"],"sourceUrl":"http://ieeexplore.ieee.org/document/11345176","publishedAt":"2026-01-12T13:22:14.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":[],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":"2026-01-12T13:22:14.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":null,"aiComponentTargeted":"model","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":"peer_reviewed","atlasIds":null}}
