CVE-2023-6346Network attack vector

Heap corruption via WebAudio use after free

Published Nov 29, 2023 · Updated Feb 13, 2025

Use-after-free in Google Chrome WebAudio before 119.0.6045.199 allows remote attackers to exploit heap corruption via crafted HTML pages. The WebAudio implementation accesses an object after it has been freed while processing attacker-controlled page content, corrupting heap state. Exploitation requires a user to load the crafted page; the published record confirms heap corruption but does not specify whether code execution follows.
