The osv/ directory has not been updated since 2026-03-10, and OSV.dev imports it

Summary

The native OSV files under osv/ in this repository appear to have been published once — a single commit on 2026-03-10 — and never regenerated, while the OVAL files (azurelinux-3.0-oval.xml, cbl-mariner-2.0-oval.xml) are updated daily. OSV.dev's importer consumes exactly that osv/ directory (their source.yaml, entry azurelinux: repo_url: https://github.com/microsoft/AzureLinuxVulnerabilityData.git, directory_path: 'osv'), so the Azure Linux:2 / Azure Linux:3 ecosystems on OSV.dev are frozen, and every OSV.dev consumer silently misses everything Azure Linux has published since the spring.

Evidence (sampled 2026-08-28)

• git log -- osv on this repository: exactly one commit (1c040ad, 2026-03-10), authored by CBL-Mariner-Bot with the message "Added latest version of OSV files: 1773178605" — the phrasing suggests an automated export that was meant to recur and ran once.
• OVAL: current (this repository's latest commit 2026-08-27 at the time of sampling); it contains, for example, CVE-2026-10536 (curl), CVE-2026-42250 (bzip2), CVE-2025-5278 (coreutils).
• The osv/ files do not contain those advisories.
• Downstream effect on OSV.dev: POST /v1/query {"package":{"name":"curl","ecosystem":"Azure Linux:3"}} returns 14 records, every one modified: 2026-04-21 (their last processing of the frozen snapshot); same for expat (12 records, same date).

Impact

Scanners consuming the OVAL directly (grype, trivy) are current; anything consuming OSV.dev's Azure Linux data is ~5 months stale. In a three-scanner differential over a digest-pinned Azure Linux 3.0 image, the OVAL consumers report 140 (package, CVE) findings — 135 of them 2026 CVEs, all with real fixed versions — that an OSV.dev-sourced scanner misses entirely.

Ask

Either regenerate osv/ on the same cadence as the OVAL (it looks like a one-time export that was intended to be continuous — OSV.dev onboarded it as a production source in April, google/osv.dev#5175), or, if the OSV export is discontinued, say so in the README and let OSV.dev know so they can point their importer elsewhere or retire the ecosystem rather than serving frozen data.

Happy to provide the full 140-finding list or any other detail.

まず osv/ ディレクトリ、その git 履歴、および azurelinux-3.0-oval.xml と cbl-mariner-2.0-oval.xml の公開状況を調査します。OSV スナップショットを現在の OVAL アドバイザリと比較し、既存の定期エクスポート経路が言及されているか、利用可能かを確認します。OSV データが想定された頻度で再生成されるか、または README に廃止が記録され、OSV.dev に通知されれば完了です。
