Over six months BigSleep reported more vulnerabilities than Fuzzilli (45 versus 37), with a 25% overlap in specific bugs, and dedicated experiments estimated overlap near 60%. The authors conclude that fuzzing and LLM-based analysis are complementary and recommend vendors use both.","solution":"N/A -- no mitigation discussed in source.","labels":["security","research"],"sourceUrl":"https://projectzero.google/2026/10/fuzzing-v-AI.html","publishedAt":"2026-10-27T07:00:00.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"low","attackType":[],"issueType":"news","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":["Google"],"affectedVendorsRaw":["BigSleep","Fuzzilli","V8","Chrome"],"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":"2026-10-27T07:00:00.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity"],"aiComponentTargeted":null,"llmSpecific":true,"classifierConfidence":0.8,"researchCategory":null,"atlasIds":null}}
