Vulnerability in Kernel (CVE-2024-41098)

Summary

Vulnerability in Kernel (CVE-2024-41098). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 4.19.321, 5.4.283, 5.10.225, 5.15.166, 6.1.108, 6.6.37, 6.9.8 or later.

Original description

The description as published by the source.

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

ata: libata-core: Fix null pointer dereference on error

If the ata_port_alloc() call in ata_host_alloc() fails,
ata_host_release() will get called.

However, the code in ata_host_release() tries to free ata_port struct
members unconditionally, which can lead to the following:

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 4.19.321, 5.4.283, 5.10.225, 5.15.166, 6.1.108, 6.6.37, 6.9.8
```
ステージング環境で 4.19.321, 5.4.283, 5.10.225, 5.15.166, 6.1.108, 6.6.37, 6.9.8 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。
