Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Mandates timely identification, reporting, and remediation of software flaws like the integer overflow in ExecuTorch model loading via patching to the fixing commit.

SI-16 Memory Protection partial match

prevent

Implements memory protection mechanisms such as address space layout randomization and guard pages to mitigate exploitation from overlapping allocations caused by the integer overflow.

SI-10 Information Input Validation partial match

prevent

Requires validation of ExecuTorch model inputs to detect and reject specially crafted files that trigger the integer overflow vulnerability.

NVD Description

An integer overflow vulnerability in the loading of ExecuTorch models can cause overlapping allocations, potentially resulting in code execution or other undesirable effects. This issue affects ExecuTorch prior to commit d158236b1dc84539c1b16843bc74054c9dcba006.

Deeper analysisAI

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.
