CVE-2025-1916Network attack vector

Heap corruption via Profiles use-after-free

Published Mar 5, 2025 · Updated Feb 26, 2026

Use after free in Profiles in Google Chrome before 134.0.6998.35 allows attackers to corrupt heap memory through a crafted HTML page. The public Chromium issue is access-restricted, so Google has not disclosed which Profiles object is freed or what operation later reuses its stale reference. Exploitation requires a user to install a malicious extension and then encounter the crafted page; the published consequence is limited to heap corruption.
