Heap corruption via Blink Layout type confusion

Published Apr 5, 2022 · Updated Aug 2, 2024

Type confusion in Blink Layout in Google Chrome before 99.0.4844.51 allows remote attackers to corrupt heap memory via crafted HTML. Google identifies Blink Layout as the locus but has not published the mismatched object types or the operation that confuses them. A user must open the crafted page; successful heap corruption can compromise the browser process, while the post-corruption primitive remains undisclosed.
