🧬 CWE Related 99
slug: cwe-416

Explanation

CWE-416は「メモリを解放した後にそのメモリを使ってしまう」欠陥です。 C/C++のような手動メモリ管理言語で頻発し、攻撃者はこれを利用して任意のコードを実行できることが多いです。 ブラウザのJavaScriptエンジン (V8, JavaScriptCore) でよく見つかり、ブラウザ経由のゼロデイ攻撃の典型的な原因となります。
📌 Example
Pwn2Own (年次ハッキングコンテスト) で、毎年ブラウザに対するUse-After-Free 攻撃が成功し、賞金10万ドル超を獲得する事例が続いています。
