Polar: LLM-Powered Synthesis of Real-World Cyber Evidence for Prioritization and Mitigation

Luoxi Tang, Yuqiao Meng, Ankita Patra وآخرون · 2026

Cyber threat analysis increasingly depends on evidence distributed across vendor advisories, vulnerability databases, and threat intelligence sources. Turning these fragmented observations into timely decisions requires models to connect technical severity with evolving exploitation evidence and available defensive act …

Understanding and Mitigating Inference-Time Overreliance Using Agentic Memory

Luoxi Tang, Yuqiao Meng, Nilesh Auradkar وآخرون · 2026

Agentic memory allows LLM agents to reuse past experience, yet retrieved memories can also distort inference even when they are benign, correctly stored, and appropriately retrieved. We study this failure mode, which we call memory over-reliance. Across benchmarks and memory architectures, we find that memory is useful …

When Correct Memory Goes Wrong: Fuzzing Persistent Memory Use in LLM Agents

Yuqiao Meng, Luoxi Tang, Yingxue Zhang وآخرون · 2026

Persistent memory helps LLM agents carry information across long interactions, but correct memory can still be used incorrectly when queries change or memory states evolve. Existing work mainly studies memory content errors or evaluates fixed test cases, leaving memory-use failures hard to discover systematically. We f …
