Vulnerability in Kernel (CVE-2024-26916)

Summary

Vulnerability in Kernel (CVE-2024-26916). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 5.15.149, 6.1.79, 6.6.18, 6.7.6 or later.

Original description

The description as published by the source.

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

Revert "drm/amd: flush any delayed gfxoff on suspend entry"

commit ab4750332dbe ("drm/amdgpu/sdma5.2: add begin/end_use ring
callbacks") caused GFXOFF control to be used more heavily and the
codepath that was removed from commit 0dee72639533 ("drm/amd: flush any
delayed gfxoff on suspend entry") now can be exercised at suspend again.

Users report that by using GNOME to suspend the lockscreen trigger will
cause SDMA traffic and the system can deadlock.

This reverts commit 0dee726395333fea833eaaf838bc80962df886c8.

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 5.15.149, 6.1.79, 6.6.18, 6.7.6
```
ステージング環境で 5.15.149, 6.1.79, 6.6.18, 6.7.6 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。
