Vulnerability in Kernel (CVE-2024-42319)

Summary

Vulnerability in Kernel (CVE-2024-42319). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 6.1.120, 6.6.64, 6.10.3 or later.

Original description

The description as published by the source.

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

mailbox: mtk-cmdq: Move devm_mbox_controller_register() after devm_pm_runtime_enable()

When mtk-cmdq unbinds, a WARN_ON message with condition
pm_runtime_get_sync() < 0 occurs.

According to the call tracei below:
cmdq_mbox_shutdown
mbox_free_channel
mbox_controller_unregister
__devm_mbox_controller_unregister
...

The root cause can be deduced to be calling pm_runtime_get_sync() after
calling pm_runtime_disable() as observed below:

CMDQ driver uses devm_mbox_controller_register() in cmdq_probe()
to bind the cmdq device to the mbox_controller, so
devm_mbox_controller_unregister() will automatically unregister
the device bound to the mailbox controller when the device-managed
resource is removed. That means devm_mbox_controller_unregister()
and cmdq_mbox_shoutdown() will be called after cmdq_remove().
CMDQ driver also uses devm_pm_runtime_enable() in cmdq_probe() after
devm_mbox_controller_register(), so that devm_pm_runtime_disable()
will be called after cmdq_remove(), but before
devm_mbox_controller_unregister().

To fix this problem, cmdq_probe() needs to move
devm_mbox_controller_register() after devm_pm_runtime_enable() to make
devm_pm_runtime_disable() be called after
devm_mbox_controller_unregister().

🔧 How to fix

Update to 6.1.120, 6.6.64, 6.10.3.

🛡️ Workaround

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 6.1.120, 6.6.64, 6.10.3
```
ステージング環境で 6.1.120, 6.6.64, 6.10.3 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。
