# CVE-2025-30404: ExecuTorch integer overflow vulnerability

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.6% , percentile 49: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 49% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes executorch (PyPI) < 0.7.0, fixed in 0.7.0 ; org.pytorch:executorch-android (Maven) < 0.7.0, fixed in 0.7.0 ; github.com/pytorch/executorch (Swift) < 0.7.0, fixed in 0.7.0 . Check your lockfile, including transitive dependencies.

## What it is

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.

## Affected packages

- PyPI `executorch` < 0.7.0 → fixed: 0.7.0
- Maven `org.pytorch:executorch-android` < 0.7.0 → fixed: 0.7.0
- Swift `github.com/pytorch/executorch` < 0.7.0 → fixed: 0.7.0

## Affected products (CVE record)

- Meta Platforms, Inc ExecuTorch: < https://github.com/pytorch/executorch/commit/d158236b1dc84539c1b16843bc74054c9dcba006

## Severity

- CISA-ADP CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.62% probability of exploitation activity in the next 30 days; percentile 49.
