Heap corruption via invalidated layout iterator
Published Nov 1, 2022 · Updated Nov 12, 2024
Use-after-free in Google Chrome's Layout component before 107.0.5304.62 allows remote attackers to corrupt heap memory via crafted HTML. During LocalFrameView::PerformLayout, the layout subtree-root container is modified while a loop traverses it, invalidating the iterator and leaving a freed LayoutObject reachable. A user must load the attacker-controlled page; the public reproduction demonstrates a sanitizer-detected renderer crash, but not code execution.
