UBUNTU-CVE-2023-53396

Vulnérabilité dans linux-hwe-edge (UBUNTU-CVE-2023-53396)

Résumé

Vulnérabilité dans linux-hwe-edge (UBUNTU-CVE-2023-53396). Risque d'opérations non autorisées ou de divulgation. Atténuation : mise à jour vers 5.15.0-1044.49~20.04.1 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: ubifs: Fix memory leak in do_rename If renaming a file in an encrypted directory, function fscrypt_setup_filename allocates memory for a file name. This name is never used, and before returning to the caller the memory for it is not freed. When running kmemleak on it we see that it is registered as a leak. The report below is triggered by a simple program 'rename' that renames a file in an encrypted directory: unreferenced object 0xffff888101502840 (size 32): comm "rename", pid 9404, jiffies 4302582475 (age 435.735s) backtrace: __kmem_cache_alloc_node __kmalloc fscrypt_setup_filename do_rename ubifs_rename vfs_rename do_renameat2 To fix this we can remove the call to fscrypt_setup_filename as it's not needed.

Actions de réponse

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

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
Apply patch patch
```
Upgrade linux-hwe-edge to 5.15.0-1044.49~20.04.1
```
ステージング環境で 5.15.0-1044.49~20.04.1 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
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。
