ReasonBreak: Probing Vulnerabilities in Reasoning-Enabled Vision-Language-Action Models for Autonomous Driving

Mohammadreza Teymoorianfard, Jean-Philippe Monteuuis, Jonathan Petit +1

Vision-Language-Action (VLA) models with integrated reasoning have been proposed for end-to-end autonomous driving, assuming a tight coupling between reasoning and trajectory gener…

Forget to Know, Remember to Use: Context-Aware Unlearning for Large Language Models

Yuefeng Peng, Parnian Afshar, Megan Ganji +4

Large language models may encode sensitive information or outdated knowledge that needs to be removed, to ensure responsible and compliant model responses. Unlearning has emerged a…

Codec-Robust Attacks on Audio LLMs

Jaechul Roh, Jean-Philippe Monteuuis, Jonathan Petit +1

Prior attacks on Audio Large Language Models (Audio LLMs) demonstrated that carefully crafted waveform-domain perturbations can force targeted adversarial outputs. As a defense mec…

Membership Inference Attacks on Vision-Language-Action Models

Yuefeng Peng, Mingzhe Li, Kejing Xia +2

Membership inference attacks (MIAs) have been extensively studied in large language models (LLMs) and vision-language models (VLMs), yet their implications for vision-language-acti…

Benign Fine-Tuning Breaks Safety Alignment in Audio LLMs

Jaechul Roh, Amir Houmansadr

Prior work shows that fine-tuning aligned models on benign data degrades safety in text and vision modalities, and that proximity to harmful content in representation space predict…

Bob's Confetti: Phonetic Memorization Attacks in Music and Video Generation

Jaechul Roh, Zachary Novack, Yuefeng Peng +3

Generative AI systems for music and video commonly use text-based filters to prevent regurgitation of copyrighted material. We expose a significant vulnerability in this approach b…
