CVE-2022-3050Network attack vector

Heap corruption via crafted WebUI interactions

Published Sep 26, 2022 · Updated May 21, 2025

Heap-buffer overflow in Chrome WebUI on Chrome OS before 105.0.5195.52 allows remote attackers to corrupt heap memory via crafted UI interactions. Google has not published the affected WebUI code path or the incorrect memory operation that permits the out-of-bounds write. Exploitation requires remote attackers to convince a Chrome OS user to perform specific crafted UI interactions; the public record does not distinguish a crash from code execution.
