Vulnerability in Kernel (CVE-2023-53051)

Summary

Vulnerability in Kernel (CVE-2023-53051). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 4.14.312, 4.19.280, 5.4.240, 5.10.177, 5.15.105, 6.1.22, 6.2.9 or later.

Original description

The description as published by the source.

In the Linux kernel, the following vulnerability has been resolved:

dm crypt: add cond_resched() to dmcrypt_write()

The loop in dmcrypt_write may be running for unbounded amount of time,
thus we need cond_resched() in it.

This commit fixes the following warning:

🔧 How to fix

Update to 4.14.312, 4.19.280, 5.4.240, 5.10.177, 5.15.105, 6.1.22, 6.2.9.

🛡️ Workaround

Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.

🔍 Detection

Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r 'Kernel' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

Response actions

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

1
Identify exposure identify
```
grep -r 'Kernel' . | 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 Kernel 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 Kernel to 4.14.312, 4.19.280, 5.4.240, 5.10.177, 5.15.105, 6.1.22, 6.2.9
```
ステージング環境で 4.14.312, 4.19.280, 5.4.240, 5.10.177, 5.15.105, 6.1.22, 6.2.9 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。
