CVE-2026-44919
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn OpenStack Ironic through 35.x before a3f6d73, during image handling, an infinite loop in checksum calculations can occur via the file:///dev/zero URL.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

29.0.6, 32.0.2, or 35.0.2 (depending on your current branch)
- 1. Identify the currently deployed Ironic version using `openstack version` or checking the package version
- 2. Determine which upgrade path applies based on your current version: if >= 23.0.4 and < 29.0.6, upgrade to 29.0.6 or later; if >= 30.0.0 and < 32.0.2, upgrade to 32.0.2 or later; if >= 33.0.0 and < 35.0.2, upgrade to 35.0.2 or later
- 3. Review the upgrade documentation at https://docs.openstack.org/ironic/latest/
- 4. Before upgrading, back up the Ironic database and configuration files
- 5. Apply the upgrade following standard OpenStack upgrade procedures, which typically involve stopping services, running database migrations, and restarting services
- 6. Verify the upgrade was successful by checking the Ironic version and ensuring services are operational
- 7. Test that image handling with file:// URLs works correctly and does not cause infinite loops
