Vulnerability in Kernel (CVE-2024-36969)

Summary

Vulnerability in Kernel (CVE-2024-36969). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 5.15.160, 6.1.92, 6.6.32, 6.8.11, 6.9.2 or later.

Original description

The description as published by the source.

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

drm/amd/display: Fix division by zero in setup_dsc_config

When slice_height is 0, the division by slice_height in the calculation
of the number of slices will cause a division by zero driver crash. This
leaves the kernel in a state that requires a reboot. This patch adds a
check to avoid the division by zero.

The stack trace below is for the 6.8.4 Kernel. I reproduced the issue on
a Z16 Gen 2 Lenovo Thinkpad with a Apple Studio Display monitor
connected via Thunderbolt. The amdgpu driver crashed with this exception
when I rebooted the system with the monitor connected.

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 5.15.160, 6.1.92, 6.6.32, 6.8.11, 6.9.2
```
ステージング環境で 5.15.160, 6.1.92, 6.6.32, 6.8.11, 6.9.2 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。
