{"data":{"id":"5be48907-a85a-4dc9-85e5-9071efbf1d58","title":"Safety Kernel: Mechanistic Alignment for Cross-Lingual Defense in LLMs","summary":"Researchers analyze cross-lingual safety behavior in large language models at the neuron level and identify a compact set of safety-related neurons shared across languages, called the safety kernel (SK). They introduce SK-Masked LoRA, which restricts LoRA adaptation to the feed-forward network output dimensions corresponding to the SK. According to the paper, this substantially reduces attack success rates across multiple languages, including languages excluded from SK discovery, while changing only a small fraction of neuron coordinates.","solution":"N/A -- no mitigation discussed in source.","labels":["research","safety"],"sourceUrl":"https://arxiv.org/abs/2610.24614v1","publishedAt":"2026-10-17T10:39:50.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["jailbreak"],"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":"2026-10-17T10:39:50.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["safety"],"aiComponentTargeted":"model","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":"preprint","atlasIds":["AML.T0054"]}}
