Groundhog Bit-Flip Attack: Seeding Infinite Generation Loops in Mixture-of-Experts LLMs through Bit Flips

By identifying and flipping routing-layer bits associated with related expert activations, GBFA substantially extends the decoding token usage across three different LLM modes: conversational, reasoning, and agentic tasks, while largely preserving semantic fidelity.

SLAC: Access-Driven CPU-to-GPU Side-channel Attacks via System-Level Cache on Apple Silicon

This work targets Apple Silicon heterogeneous SoCs and discovers that GPU memory accesses leave set-level footprints in the shared SLC, observable to an unprivileged CPU process, which enables the first fine-grained, access-driven, Prime+Probe-style CPU-to-GPU cache side-channel attacks against GPU workloads.
