Vulnerability in Kernel (CVE-2024-46715)

Summary

Vulnerability in Kernel (CVE-2024-46715). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 5.15.203, 6.1.109, 6.6.50, 6.10.9 or later.

Original description

The description as published by the source.

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

driver: iio: add missing checks on iio_info's callback access

Some callbacks from iio_info structure are accessed without any check, so
if a driver doesn't implement them trying to access the corresponding
sysfs entries produce a kernel oops such as:

[ 2203.527791] Unable to handle kernel NULL pointer dereference at virtual address 00000000 when execute

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 5.15.203, 6.1.109, 6.6.50, 6.10.9
```
ステージング環境で 5.15.203, 6.1.109, 6.6.50, 6.10.9 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。
