CVE-2025-30405: ExecuTorch integer overflow vulnerability
An integer overflow vulnerability in the loading of ExecuTorch models can cause objects to be placed outside their allocated memory area, potentially resulting in code execution or other undesirable effects.
CVSS 9.8 Critical EPSS 0.6% · p49
Should you act?
Critical and remotely reachable
No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- 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.
