Google Chrome の脆弱性 8件が修正：リモート・コード実行などの可能性 https://iototsecnews.jp/2026/03/24/chrome-security-update-fixes-8-vulnerabilities-that-could-enable-remote-code-execution/ 訳者後書：今回のアップデートで修正された脆弱性の多くは、メモリ管理の不備に起因しています。たとえば、ヒープバッファ・オーバーフローの脆弱性 CVE-2026-4673／CVE-2026-4675 は、確保された領域を超えてデータが書き込まれることで発動されます。また、解放後メモリ使用 (use-after-free) の脆弱性 CVE-2026-4676／CVE-2026-4678／CVE-2026-4680 は、すでに解放されたメモリ領域にプログラムがアクセスし続けることで発動します。その他にも、境界外読み取りの脆弱性 CVE-2026-4674／CVE-2026-4677 や、整数オーバーフローの脆弱性 CVE-2026-4679 などは、メモリの扱いにおける予期せぬ動作を生じます。こうした低レイヤーでの管理ミスが、攻撃者にシステム制御を許すきっかけとなります。ご利用のチームは、ご注意ください。 #Chrome #CVE20264673 #CVE20264674 #CVE20264675 #CVE20264676 #CVE20264677 #CVE20264678 #CVE20264679 #CVE20264680 #Google #Vulnerability
