CVE-2024-1077Network attack vector

Heap corruption via Network use after free

Published Jan 30, 2024 · Updated Jun 3, 2025

Use after free in Google Chrome's Network component before 121.0.6167.139 allows remote attackers to corrupt heap memory via a malicious file. Public vendor material identifies stale-object access in Network but does not disclose the affected object, code path, or lifetime error that frees it too early. Exploitation requires user interaction with the malicious file and can compromise confidentiality, integrity, and availability.
