Summary

  • renew the five v0.26.1 candidate image fingerprints from failed candidate run 33873930773
  • add exact no-fix CVE-2026-85091 exceptions for zlib1g after reviewing each shipped executable
  • advance independent live baseline pins

Security decision

CVE-2026-85091 affects a stalled non-blocking gzwrite followed by gzprintf/gzvprintf. The exact five Linux AMD64 candidate executables do not link libz and contain none of libz.so, gz_vacate, gzwrite, gzprintf, or gzvprintf. The existing detector and schema remain unchanged. Each exception binds the exact image, source evidence, base and application DiffIDs, process config, component layer, and reviewed file hashes, and expires 2026-09-18.

Verification

  • exact checker against regenerated Syft 1.45.1, Grype 0.114.0, OCI, and rootfs evidence for all five images: invalid=0
  • python3 -m unittest release/scripts/test_check_advisory_baselines.py
  • python3 -m unittest release/scripts/test_release_candidate.py release/scripts/test_registry_release.py
  • release/scripts/registry-release validate-current
  • git diff --check
