ALPINE-CVE-2025-58146

Vulnerability in xen (ALPINE-CVE-2025-58146)

Summary

Vulnerability in xen (ALPINE-CVE-2025-58146). Risk of unauthorized operations or information disclosure.

Original description

The description as published by the source.

There are multiple issues.

Updates to the XAPI database sanitise input strings, but try
generating the notification using the unsanitised input. This
causes the database's event thread to terminate and cease further
processing.
XAPI's UTF-8 encoder implements v3.0 of the Unicode spec, but XAPI
uses libraries which conform to the stricter v3.1 of the Unicode
spec. This causes some strings to be accepted as valid UTF-8 by
XAPI, but rejected by other libraries in use. Notably, such strings
can be entered into the database, after which the database can no
longer be loaded.
There is no input sanitisation for Map/Set updates on objects in the
XAPI database.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

1
Identify exposure identify
```
grep -r 'xen' . | grep -v node_modules
```
リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で xen を grep し、稼働しているサービス・バージョンを把握する。
2
Post-deployment verification verify
```
Confirm patched version is live in production
```
パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
