CVE-2022-2620Network attack vector

Heap corruption via WebUI use-after-free

Published Aug 12, 2022 · Updated Aug 3, 2024

Use-after-free in Google Chrome WebUI before 104.0.5112.79 allows remote attackers to corrupt heap memory through specific UI interactions. Google identifies WebUI as the affected locus but has not published which object is freed prematurely or how a later UI operation reuses it. Exploitation applies to ChromeOS and requires convincing a user to perform the triggering interactions; the public record does not establish code execution or another downstream effect.
