Ollama Out-of-Bounds Read Vulnerability Allows Remote Process Memory Leak

Ollama, one of the most popular frameworks for running LLMs locally, has been found to contain a critical out-of-bounds read vulnerability in its GGUF model parser. This flaw allows remote attackers to leak sensitive data from process memory, including model weights, API keys, and other confidential information that may be accessible during inference.

The vulnerability is particularly concerning for production deployments where Ollama instances are exposed to untrusted networks or integrated into multi-tenant environments. Users should immediately update to the latest patched version and review their security configurations. For organizations running Ollama in sensitive contexts, consider implementing network isolation, access controls, and monitoring until patches are confirmed stable.

This incident underscores the importance of security audits in the local LLM ecosystem. Read the full vulnerability report for technical details and remediation steps.
