Vulnérabilité dans linux-hwe-edge (UBUNTU-CVE-2025-21729)

Résumé

Vulnérabilité dans linux-hwe-edge (UBUNTU-CVE-2025-21729). L'exploitation peut entraîner la prise de contrôle totale du système. Atténuation : mise à jour vers 6.8.0-1043.45~22.04.1 ou plus.

Description d'origine

La description telle que publiée par la source (souvent en anglais).

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: fix race between cancel_hw_scan and hw_scan completion The rtwdev->scanning flag isn't protected by mutex originally, so cancel_hw_scan can pass the condition, but suddenly hw_scan completion unset the flag and calls ieee80211_scan_completed() that will free local->hw_scan_req. Then, cancel_hw_scan raises null-ptr-deref and use-after-free. Fix it by moving the check condition to where protected by mutex.

Actions de réponse

Étapes concrètes et exemples de commandes que les équipes SOC/SRE doivent exécuter dans l'ordre

  1. 1
    Identify exposure identify 
    grep -r 'linux-hwe-edge' . | 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 linux-hwe-edge を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Apply patch patch 
    Upgrade linux-hwe-edge to 6.8.0-1043.45~22.04.1

    ステージング環境で 6.8.0-1043.45~22.04.1 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスを含めること。

  3. 3
    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。
