GHSA-33r8-vrx9-rmcv — executorch
Fix: pytorch/executorch@8f062d3GHSA-33r8-vrx9-rmcv is a CWE-680 vulnerability in executorch. No vendor fix is recorded yet; mitigation options are listed below.
ExecuTorch integer overflow vulnerability leads to code execution
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Description
An integer overflow vulnerability in the loading of ExecuTorch models can cause smaller-than-expected memory regions to be allocated, potentially resulting in code execution or other undesirable effects. This issue affects ExecuTorch prior to commit 8f062d3f661e20bb19b24b767b9a9a46e8359f2b.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for executorch, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of executorch has shipped for GHSA-33r8-vrx9-rmcv yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-33r8-vrx9-rmcv can be triaged on real exposure rather than presence alone.
Tailored to GHSA-33r8-vrx9-rmcv. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-33r8-vrx9-rmcv in your dependencies?
O3 Security finds GHSA-33r8-vrx9-rmcv across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
