Code execution via unsafe kernel-cache deserialization
Published Sep 9, 2026 · Updated Sep 9, 2026
Unsafe deserialization in TileLang 0.1.0 through 0.1.14 allows remote authenticated users to execute code through a poisoned kernel cache. KernelCache._load_kernel_from_disk passes params.pkl contents to cloudpickle.load without integrity validation, causing attacker-supplied pickle reduction logic to run. Exploitation requires write access to TILELANG_CACHE_DIR and a victim process to load the forged cache entry; the resulting code runs with that process's privileges.
