Vulnerability in Kernel (CVE-2024-27001)

Summary

Vulnerability in Kernel (CVE-2024-27001). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 4.19.313, 5.4.275, 5.10.216, 5.15.157, 6.1.88, 6.6.29, 6.8.8 or later.

Original description

The description as published by the source.

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

comedi: vmk80xx: fix incomplete endpoint checking

While vmk80xx does have endpoint checking implemented, some things
can fall through the cracks. Depending on the hardware model,
URBs can have either bulk or interrupt type, and current version
of vmk80xx_find_usb_endpoints() function does not take that fully
into account. While this warning does not seem to be too harmful,
at the very least it will crash systems with 'panic_on_warn' set on
them.

Fix the issue found by Syzkaller [1] by somewhat simplifying the
endpoint checking process with usb_find_common_endpoints() and
ensuring that only expected endpoint types are present.

This patch has not been tested on real hardware.

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 4.19.313, 5.4.275, 5.10.216, 5.15.157, 6.1.88, 6.6.29, 6.8.8
```
ステージング環境で 4.19.313, 5.4.275, 5.10.216, 5.15.157, 6.1.88, 6.6.29, 6.8.8 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。
