UBUNTU-CVE-2023-2008
Vulnérabilité dans linux-hwe-edge (UBUNTU-CVE-2023-2008)
Résumé
Vulnérabilité dans linux-hwe-edge (UBUNTU-CVE-2023-2008). L'exploitation peut entraîner la prise de contrôle totale du système. Atténuation : mise à jour vers 5.4.0-1085.92~18.04.1 ou plus.
Description d'origine
La description telle que publiée par la source (souvent en anglais).
A flaw was found in the Linux kernel's udmabuf device driver. The specific flaw exists within a fault handler. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an array. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel.

Actions de réponse
Étapes concrètes et exemples de commandes que les équipes SOC/SRE doivent exécuter dans l'ordre
-
1Identify 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。 -
2Apply patch patch
Upgrade linux-hwe-edge to 5.4.0-1085.92~18.04.1ステージング環境で 5.4.0-1085.92~18.04.1 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。
-
3Post-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。
