CVE-2022-1134Public exploitNetwork attack vector

Renderer code execution via SuperIC receiver mismatch

Published Jul 22, 2022 · Updated Aug 2, 2024

Type confusion in V8 in Google Chrome before 100.0.4896.60 allows remote attackers to execute code in the renderer via crafted HTML. A SuperIC handler validates the accessor against the lookup-start object's map but invokes it with an incompatible receiver, corrupting type assumptions. Visiting a malicious site is required, and resulting code execution remains inside Chrome's renderer sandbox.
