How to Fix CVE-2025-6032

To remediate this vulnerability, upgrade all affected Github.com/containers/podman/v4 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/containers/podman/v4 fixed: Latest secure release 
Upgrade github.com/containers/podman/v4 to Latest secure release
github.com/containers/podman/v5 fixed: 5.5.2 
Upgrade github.com/containers/podman/v5 to 5.5.2
Verify Direct and Transitive Dependencies

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

inspect dependencies for github.com/containers/podman/v4

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-6032, inspect your project dependencies for Github.com/containers/podman/v4:

inspect dependencies for github.com/containers/podman/v4

Analyze the terminal output to locate any version of Github.com/containers/podman/v4 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.5.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-295: Improper Certificate Validation, where the product does not validate, or incorrectly validates, a certificate. In Github.com/containers/podman/v4, 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

### Impact The podman machine init command fails to verify the TLS certificate when downloading the VM images from an OCI registry (which it does by default since 5.0.0) allowing a possible Man In The Middle attack. ### Patches https://github.com/containers/podman/commit/726b506acc8a00d99f1a3a1357ecf619a1f798c3 Fixed in v5.5.2 ### Workarounds Download the disk image manually via some other tool that verifies the TLS connection. Then pass the local image as file path (podman machine init --image ./somepath)
