CVE-2023-2457Network attack vector

Heap corruption via crafted audio file

Published May 12, 2023 · Updated Oct 3, 2024

An out-of-bounds write in Google Chrome's ChromeOS Audio Server before 113.0.5672.114 allows remote attackers to corrupt heap memory. The public record identifies a crafted audio file as the trigger but does not disclose the affected function, buffer, or unchecked write. A user must process attacker-controlled audio; the documented consequence is heap corruption, with the exact post-corruption behavior undisclosed.
