Amplifying Latency and Cost of LLM Inference via Rowhammer Attack
Researchers chain Rowhammer bit-flips into Triton's JIT-compiled GPU kernels to silently inflate LLM inference latency and cost — a novel denial-of-wallet vector for AI infrastructure.

arXiv:2610.30798v1 Announce Type: new Abstract: Large language models (LLMs) achieve high inference efficiency using optimized GPU kernels generated by just-in-time (JIT) compilation frameworks such as Triton. Triton compiles GPU kernels through an MLIR/LLVM-based pipeline. We investigate whether a Rowhammer-induced bit-flip in the CPU's DRAM can degrade GPU-based LLM inference performance while preserving output correctness. We present LLVMhammer, the first Rowhammer attack that causes LLM inf
Editorial Analysis
Organisations running GPU-intensive LLM workloads in shared cloud environments face a new availability and cost-inflation risk if hardware-level mitigations are absent.
Verify that GPU instances used for LLM inference have ECC memory enabled and that JIT compilation integrity is monitored.
