Summary

Vulnerability in Kernel (CVE-2024-50266). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 6.11.8 or later.

Original description

The description as published by the source.

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

clk: qcom: videocc-sm8350: use HW_CTRL_TRIGGER for vcodec GDSCs

A recent change in the venus driver results in a stuck clock on the
Lenovo ThinkPad X13s, for example, when streaming video in firefox:

video_cc_mvs0_clk status stuck at 'off'
WARNING: CPU: 6 PID: 2885 at drivers/clk/qcom/clk-branch.c:87 clk_branch_wait+0x144/0x15c

using the out-of-tree sm8350/sc8280xp venus support. [1]

Update also the sm8350/sc8280xp GDSC definitions so that the hw control
mode can be changed at runtime as the venus driver now requires.

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 6.11.8
```
ステージング環境で 6.11.8 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。
