Comment 1 Lokesh Mandvekar 2026-06-18 19:16:34 UTC 
fedora rawhide should be unaffected as it already has version number higher than required for the fix. Created an upstream PR for v5.8 https://github.com/podman-container-tools/podman/pull/28971
Comment 2 Lokesh Mandvekar 2026-07-10 14:31:26 UTC 
The x/crypto bump is now done and shipped in podman v5.8 on Fedora.
