How to Fix CVE-2025-57275

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

spdk fixed: 25.9 
pip install spdk>=25.9
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 spdk

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2025-57275, inspect your installed packages using pip:

pip show spdk

Analyze the terminal output to locate any version of Spdk in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 25.9), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow'), where the product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer. In Spdk, 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.
