Vulnerability in Kernel (CVE-2024-50236)

Summary

Vulnerability in Kernel (CVE-2024-50236). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 4.19.323, 5.4.285, 5.10.229, 5.15.171, 6.1.116, 6.6.60, 6.11.7 or later.

Original description

The description as published by the source.

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

wifi: ath10k: Fix memory leak in management tx

In the current logic, memory is allocated for storing the MSDU context
during management packet TX but this memory is not being freed during
management TX completion. Similar leaks are seen in the management TX
cleanup logic.

Kmemleak reports this problem as below,

unreferenced object 0xffffff80b64ed250 (size 16):
comm "kworker/u16:7", pid 148, jiffies 4294687130 (age 714.199s)
hex dump (first 16 bytes):

backtrace:

Free the memory during completion and cleanup to fix the leak.

Protect the mgmt_pending_tx idr_remove() operation in
ath10k_wmi_tlv_op_cleanup_mgmt_tx_send() using ar->data_lock similar to
other instances.

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 4.19.323, 5.4.285, 5.10.229, 5.15.171, 6.1.116, 6.6.60, 6.11.7
```
ステージング環境で 4.19.323, 5.4.285, 5.10.229, 5.15.171, 6.1.116, 6.6.60, 6.11.7 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。
