CVE-2026-113343: Google Chrome memory corruption in Sandbox code execution

CVE-2026-113343 · Severity: info · Published 2026-10-20

Google Chrome is a web browser used by billions of people worldwide to view websites and web applications. A memory corruption flaw in Chrome's sandbox security mechanism allows a remote attacker to execute arbitrary code within the sandboxed environment by tricking a user into visiting a malicious webpage. While the exploit runs inside the sandbox rather than at full system privileges, it could be used as part of a two-stage attack to compromise the browser or system.
