Vulnerability in Kernel (CVE-2025-40113)

Summary

Vulnerability in Kernel (CVE-2025-40113). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 6.17.3 or later.

Original description

The description as published by the source.

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

remoteproc: qcom: pas: Shutdown lite ADSP DTB on X1E

The ADSP firmware on X1E has separate firmware binaries for the main
firmware and the DTB. The same applies for the "lite" firmware loaded by
the boot firmware.

When preparing to load the new ADSP firmware we shutdown the lite_pas_id
for the main firmware, but we don't shutdown the corresponding lite pas_id
for the DTB. The fact that we're leaving it "running" forever becomes
obvious if you try to reuse (or just access) the memory region used by the
"lite" firmware: The &adsp_boot_mem is accessible, but accessing the
&adsp_boot_dtb_mem results in a crash.

We don't support reusing the memory regions currently, but nevertheless we
should not keep part of the lite firmware running. Fix this by adding the
lite_dtb_pas_id and shutting it down as well.

We don't have a way to detect if the lite firmware is actually running yet,
so ignore the return status of qcom_scm_pas_shutdown() for now. This was
already the case before, the assignment to "ret" is not used anywhere.

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 6.17.3
```
ステージング環境で 6.17.3 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。
