Summary
CVE-2025-30404 is a critical-severity Integer Overflow or Wraparound (CWE-190) vulnerability in Facebook (inferred from references). Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 26.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-2 (Flaw Remediation) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2025-30404 is an integer overflow vulnerability (CWE-190) in the loading of ExecuTorch models, which can cause overlapping allocations and potentially result in code execution or other undesirable effects. The vulnerability affects ExecuTorch prior to commit d158236b1dc84539c1b16843bc74054c9dcba006 and carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), marking it as critical.
The vulnerability can be exploited remotely by any unauthenticated attacker with low complexity and no user interaction required. By providing a specially crafted ExecuTorch model for loading, an attacker could trigger the integer overflow, leading to overlapping memory allocations that enable arbitrary code execution, data corruption, or denial of service with high impacts on confidentiality, integrity, and availability.
Mitigation is provided through the fixing commit d158236b1dc84539c1b16843bc74054c9dcba006 in the PyTorch ExecuTorch GitHub repository. Security practitioners should update to this commit or later versions. Further details are available in the Facebook security advisory at https://www.facebook.com/security/advisories/cve-2025-30404.
