CVE-2024-5157Network attack vector

Sandboxed code execution via Scheduling use-after-free

Published May 22, 2024 · Updated Mar 27, 2025

Use-after-free in Google Chrome's Scheduling component before 125.0.6422.76 allows remote attackers to execute code inside the sandbox. Google identifies Scheduling as using freed memory but has not published the affected function or object-lifetime sequence. A user must load a crafted HTML page; exploitation runs attacker-controlled code within the renderer sandbox, with no documented sandbox escape.
