PatchTheCVECVE-2026-7482: Ollama before 0.17.1 contains a heap out-of-bounds read vulnerability in the GGUF model loader
CVE-2026-7482 is a critical-severity flaw (CVSS 9.1) affecting ollama. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Ollama before 0.17.1 contains a heap out-of-bounds read vulnerability in the GGUF model loader. The /api/create endpoint accepts an attacker-supplied GGUF file in which the declared tensor offset and size exceed the file's actual length; during quantization in fs/ggml/gguf.go and server/quantization.go (WriteTo()), the server reads past the allocated heap buffer. The leaked memory contents may include environment variables, API keys, system promp
