CVE-2024-2885Network attack vector

Heap corruption via Dawn use-after-free

Published Mar 26, 2024 · Updated Mar 18, 2025

Use after free in Dawn in Google Chrome before 123.0.6312.86 allows remote attackers to corrupt heap memory via a crafted HTML page. Public records identify Dawn's object-lifetime handling but do not disclose the freed object, call path, or operation that dereferences it. A user must load attacker-controlled HTML; successful heap corruption can destabilize the browser or provide a memory-corruption primitive.
