Vulnerability in Kernel (CVE-2024-50111)

Summary

Vulnerability in Kernel (CVE-2024-50111). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 6.6.59, 6.11.6 or later.

Original description

The description as published by the source.

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

LoongArch: Enable IRQ if do_ale() triggered in irq-enabled context

Unaligned access exception can be triggered in irq-enabled context such
as user mode, in this case do_ale() may call get_user() which may cause
sleep. Then we will get:

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 6.6.59, 6.11.6
```
ステージング環境で 6.6.59, 6.11.6 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。
