CVE-2025-30404
📋 TL;DR
An integer overflow vulnerability in ExecuTorch's model loading functionality can cause overlapping memory allocations, potentially leading to arbitrary code execution. This affects all systems using ExecuTorch models prior to the patched commit. Attackers could exploit this to execute malicious code with the privileges of the ExecuTorch process.

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, or ransomware deployment.
Likely Case
Application crash (denial of service) or memory corruption leading to unpredictable behavior.
If Mitigated
Limited impact if proper sandboxing and privilege separation are implemented.
🎯 Exploit Status
Exploitation requires loading a malicious ExecuTorch model file, which could be delivered via various vectors.
