CVE-2024-0806Network attack vector

Heap corruption via Passwords use-after-free

Published Jan 23, 2024 · Updated Jun 20, 2025

Use-after-free in Passwords in Google Chrome before 121.0.6167.85 allows remote attackers to exploit heap corruption via UI interaction. Google has not published the freed object, the stale reference, or the operation that dereferences it within the Passwords component. Exploitation requires specific user interface interaction; published material establishes heap corruption but not code execution or data disclosure.
