How to Fix CVE-2025-30402

To remediate this vulnerability, upgrade all affected Executorch dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

executorch fixed: 0.7.0 
pip install executorch>=0.7.0
org.pytorch:executorch-android fixed: 0.7.0-rc1 
<dependency>
    <groupId>org.pytorch</groupId>
    <artifactId>executorch-android</artifactId>
    <version>0.7.0-rc1</version>
</dependency>
github.com/pytorch/executorch fixed: 0.7.0-rc1 
Upgrade github.com/pytorch/executorch to 0.7.0-rc1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show executorch

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2025-30402, inspect your installed packages using pip:

pip show executorch

Analyze the terminal output to locate any version of Executorch in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.7.0), your application is affected.

Note: The pip show executorch command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-122: Heap-based Buffer Overflow, where a heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). In Executorch, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A heap-buffer-overflow vulnerability in the loading of ExecuTorch methods can cause the runtime to crash and potentially result in code execution or other undesirable effects. This issue affects ExecuTorch prior to commit 93b1a0c15f7eda49b2bc46b5b4c49557b4e9810f
