CVE-2026-58659: Use of Externally-Controlled Input to Select Classes or Code

PyTorch Lightning through 2.6.5, fixed in commit d710d68, contains a remote code execution vulnerability in the loadstate function that imports and executes attacker-controlled module names from checkpoint instantiator hyperparameters. Attackers can craft malicious checkpoint files that bypass...

EUVD-2026-37204

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 BINUNICODE 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...

CVE-2026-47749 stable-diffusion.cpp: Heap buffer overflow in SHORT_BINUNICODE 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. Versions prior to master-584-0a7ae07 are vulnerable to heap buffer overflow in SHORTBINUNICODE parsing for PyTorch checkpoint files. The pickle .ckpt pars...

CVE-2026-47748 stable-diffusion.cpp: Out-of-bounds reads in PyTorch checkpoint pickle opcode parsing

stable-diffusion.cpp is a pure C/C++ library for running diffusion model Stable Diffusion, Flux, Wan, Qwen Image, Z-Image, and more inference. Versions prior to master-584-0a7ae07 are vulnerable to an out-of-bounds reads error through PyTorch checkpoint pickle opcode parsing. The pickle .ckpt...

CVE-2026-47748

CVE-2026-47748 affects stable-diffusion.cpp (C/C++ library) prior to master-584-0a7ae07. The root cause is out-of-bounds reads in the PyTorch checkpoint pickle opcode parsing in src/model.cpp, where the parser sometimes advances buffer positions without validating remaining input, allowing reads ...

CVE-2026-31250

The CosyVoice AI voice cloning platform, developed by FunAudioLLM , contains an insecure deserialization vulnerability (CWE-502) in its average_model.py tool (affected through commit 6e01309e01bc93bbeb83bdd996b1182a81aaf11e). The root cause is the use of torch.load() to process PyTorch checkpoint...

Memory Corruption

PyTorch is vulnerable to memory corruption. The vulnerability is due to an unsafe implementation in the weightsonly unpickler when loading malicious .pth checkpoint files, which allows an attacker to craft a specially designed file that can corrupt memory and potentially execute arbitrary code...
