CVE-2022-3888Network attack vector

Heap corruption via WebCodecs use-after-free

Published Nov 9, 2022 · Updated Oct 23, 2024

Use-after-free in WebCodecs in Google Chrome before 107.0.5304.106 allows remote attackers to corrupt heap memory via crafted HTML. The WebCodecs implementation accesses freed memory while processing attacker-controlled page content; public materials do not identify the affected function or object type. Exploitation requires a user to open the crafted page, and successful heap corruption can compromise data and interrupt the browser process.
