Heap corruption via URLLoader use-after-free

Published Sep 26, 2022 · Updated Oct 21, 2025

Use-after-free in Google Chrome's Network Service before 105.0.5195.52 allows remote attackers to corrupt heap memory via crafted HTML. The URLLoader NotifyCompleted path accesses an object after its lifetime ends, leaving a stale heap reference that page activity can reclaim. A user must load the crafted page; successful exploitation exposes data, alters execution, or interrupts browser operation.
