CVE-2026-47750 stable-diffusion.cpp: Heap buffer overflow in GLOBAL opcode parsing for PyTorch checkpoint files

stable-diffusion.cpp is a pure C/C++ library for running diffusion model Stable Diffusion, Flux, Wan, Qwen Image, Z-Image, and more inference. In versions prior to master-584-0a7ae07, the pickle .ckpt parser in src/model.cpp contained a heap buffer overflow vulnerability in the GLOBAL opcode...

CVE-2026-47750

The CVE-2026-47750 issue affects stable-diffusion.cpp in its pickle (.ckpt) parser (src/model.cpp). A heap buffer overflow occurs in the GLOBAL opcode handler due to missing validation while locating newline-delimited fields; a crafted .ckpt from an untrusted source can cause the parser to copy w...
