| Title | tile-ai tilelang main Remote Code Executio |
|---|
| Description | TileLang contains an unsafe deserialization vulnerability in its kernel cache system. The software uses cloudpickle (a superset of Python pickle) to serialize and deserialize kernel parameters and compiled function objects to and from disk. An attacker who can write files to the TILELANG_CACHE_DIR directory (default: ~/.tilelang/cache) can craft a malicious pickle file that executes arbitrary Python code via the cloudpickle.load() reduce protocol when a victim loads a cached kernel. This affects KernelCache._load_kernel_from_disk (tilelang/cache/kernel_cache.py:595) and AutotuneResult._load_kernel_from_disk / load_from_disk (tilelang/autotuner/param.py:368, 497).
