Summary

Vulnerability in Kernel (CVE-2024-26788). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 5.4.271, 5.10.212, 5.15.151, 6.1.81, 6.6.21, 6.7.9 or later.

Original description

The description as published by the source.

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

dmaengine: fsl-qdma: init irq after reg initialization

Initialize the qDMA irqs after the registers are configured so that
interrupts that may have been pending from a primary kernel don't get
processed by the irq handler before it is ready to and cause panic with
the following trace:

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 5.4.271, 5.10.212, 5.15.151, 6.1.81, 6.6.21, 6.7.9
```
ステージング環境で 5.4.271, 5.10.212, 5.15.151, 6.1.81, 6.6.21, 6.7.9 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。
