PRowhammer: Propagating Bit-flips from CPU to GPU ~ Artifact

This artifact demonstrates the core mechanism of PRowhammer, showing how a single Rowhammer-induced bit-flip in host DRAM can alter GPU-executed code. It provides a minimal, reproducible setup that illustrates how bit-flips in deduplicated shared library pages propagate to GPUs and modify low-level instructions while preserving syntactic validity. The artifact includes tools to identify vulnerable bit locations, emulate or induce controlled bit-flips, and observe their impact on GPU kernel execution. Through simplified examples, users can reproduce how a single bit-flip in a shared library can lead to semantically altered GPU computation, highlighting the security implications of PRowhammer in heterogeneous CPU–GPU systems.
