Jailbreak to Protect: Buffering and Reinforcing via Temporary Jailbreaking for Safe Fine-Tuning in Large Language Models
A new fine-tuning defense uses temporary jailbreaking induced by BufferLoRA to limit harmful updates, followed by merging with ReinforceLoRA via QR decomposition to restore safety while keeping task performance.
