Vulnerability in Kernel (CVE-2023-52475)

Summary

Vulnerability in Kernel (CVE-2023-52475). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 4.14.328, 4.19.297, 5.4.259, 5.10.199, 5.15.136, 6.1.59, 6.5.8 or later.

Original description

The description as published by the source.

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

Input: powermate - fix use-after-free in powermate_config_complete

syzbot has found a use-after-free bug [1] in the powermate driver. This
happens when the device is disconnected, which leads to a memory free from
the powermate_device struct. When an asynchronous control message
completes after the kfree and its callback is invoked, the lock does not
exist anymore and hence the bug.

Use usb_kill_urb() on pm->config to cancel any in-progress requests upon
device disconnection.

🔍 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 4.14.328, 4.19.297, 5.4.259, 5.10.199, 5.15.136, 6.1.59, 6.5.8
```
ステージング環境で 4.14.328, 4.19.297, 5.4.259, 5.10.199, 5.15.136, 6.1.59, 6.5.8 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。
