Rishabh Sinha	11ec2397fe	[Cache] Store cached kernel params as JSON instead of cloudpickle (#3143 ) The kernel cache and the autotuner result cache loaded params.pkl with cloudpickle.load(), so a writable cache directory allowed arbitrary code execution on the next cache hit. Kernel params are plain data, so store them as JSON via TVM's reflection (tvm.ir.save_json / load_json), which rebuilds IR nodes without executing code. Entries without params.json are treated as incomplete and rebuilt. Fixes #2817	2026-09-06 16:06:20 +08:00

[Cache] Store cached kernel params as JSON instead of cloudpickle (#3143 )

The kernel cache and the autotuner result cache loaded params.pkl with
cloudpickle.load(), so a writable cache directory allowed arbitrary code
execution on the next cache hit. Kernel params are plain data, so store
them as JSON via TVM's reflection (tvm.ir.save_json / load_json), which
rebuilds IR nodes without executing code. Entries without params.json are
treated as incomplete and rebuilt.

Fixes #2817
