# MemVulBench v1.0.0

A real-world multi-bug benchmark for C/C++ memory-safety fuzzing:
**20 admitted test units, 292 verified unique memory-vulnerability fingerprints**
(287 expected + 5 audited extra). Each unit is one real upstream project at one
unmodified historical commit, driven through a single final entry point
(identity or byte-prefix dispatch), with per-fingerprint triggering PoCs,
persisted first-fault ASan logs and SHA-256 manifests.

## Layout

```
units/<project>/                            # browsable metadata (3 small files each)
  <project>-<commit12>-v1.0.0.tar           # final aggregate image + PoCs + logs
  manifest.json                             # per-file SHA-256, upstream commit, entry map
  run-config.json                           # docker load / replay commands, ASAN_OPTIONS
fingerprint-index.json                      # 292 fingerprints -> unit, PoC, log, fix commit
manifest.json                               # release manifest (20 units, 292 fingerprints)
checks/hash-verification.json               # 20/20 image sha256 recomputed & matched
README.md                                   # this card
```

## Quickstart

```bash
pip install -U "huggingface_hub[hf_xet]"
huggingface-cli download Fisho0/MemVulBench --repo-type dataset \
    --include "units/arrow/*" --local-dir memvulbench

docker load -i memvulbench/units/arrow/arrow-8b09ecc5c690-v1.0.0.tar  # inside the tar
# replay per units/arrow/run-config.json; each PoC's first fault should match
# the corresponding final-entry log in the tar.
```
