CVE-2022-50182 high CVSS 7.8

Out-of-Bounds Read in Kernel (CVE-2022-50182)

Summary

Vulnerability in Kernel (CVE-2022-50182). Successful exploitation can lead to full system takeover. Mitigation: upgrade to 5.15.61, 5.18.18, 5.19.2 or later.

Original description

The description as published by the source.

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

media: imx-jpeg: Align upwards buffer size

The hardware can support any image size WxH,
with arbitrary W (image width) and H (image height) dimensions.

Align upwards buffer size for both encoder and decoder.
and leave the picture resolution unchanged.

For decoder, the risk of memory out of bounds can be avoided.
For both encoder and decoder, the driver will lift the limitation of
resolution alignment.

For example, the decoder can support jpeg whose resolution is 227x149
the encoder can support nv12 1080P, won't change it to 1920x1072.

❓ What is the problem

Out-of-bounds read (CWE-125) exists in Kernel.

📍 Affected scope

Check the vendor advisory for the affected versions of Kernel.

🔥 Severity

Severity: High (CVSS 7.8/10). Successful exploitation can lead to full system takeover.

🔧 How to fix

Update to 5.15.61, 5.18.18, 5.19.2.

🛡️ 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. 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. 2
    Apply patch patch 
    Upgrade Kernel to 5.15.61, 5.18.18, 5.19.2

    ステージング環境で 5.15.61, 5.18.18, 5.19.2 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. 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。
