How to Fix CVE-2025-54950

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 
<dependency>
    <groupId>org.pytorch</groupId>
    <artifactId>executorch-android</artifactId>
    <version>0.7.0</version>
</dependency>
github.com/pytorch/executorch fixed: 0.7.0 
Upgrade github.com/pytorch/executorch to 0.7.0
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-2025-54950, 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-125: Out-of-bounds Read, where the product reads data past the end, or before the beginning, of the intended buffer. 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

An out-of-bounds access vulnerability in the loading of ExecuTorch models can cause the runtime to crash and potentially result in code execution or other undesirable effects. This issue affects ExecuTorch prior to commit fb03b6f85596a8f954d97929075335255b6a58d4.
