Vulnerability in Kernel (CVE-2024-53690)

Summary

Vulnerability in Kernel (CVE-2024-53690). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 5.4.289, 5.10.233, 5.15.176, 6.1.122, 6.6.68, 6.12.7 or later.

Original description

The description as published by the source.

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

nilfs2: prevent use of deleted inode

syzbot reported a WARNING in nilfs_rmdir. [1]

Because the inode bitmap is corrupted, an inode with an inode number that
should exist as a ".nilfs" file was reassigned by nilfs_mkdir for "file0",
causing an inode duplication during execution. And this causes an
underflow of i_nlink in rmdir operations.

The inode is used twice by the same task to unmount and remove directories
".nilfs" and "file0", it trigger warning in nilfs_rmdir.

Avoid to this issue, check i_nlink in nilfs_iget(), if it is 0, it means
that this inode has been deleted, and iput is executed to reclaim it.

🔧 How to fix

Update to 5.4.289, 5.10.233, 5.15.176, 6.1.122, 6.6.68, 6.12.7.

🛡️ Workaround

Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.

🔍 Detection

Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r 'Kernel' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

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 5.4.289, 5.10.233, 5.15.176, 6.1.122, 6.6.68, 6.12.7
```
ステージング環境で 5.4.289, 5.10.233, 5.15.176, 6.1.122, 6.6.68, 6.12.7 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。
