CVE-2022-2587Public exploitNetwork attack vector

Heap corruption via unchecked audio identity copy

Published Aug 12, 2022 · Updated Aug 3, 2024

Out-of-bounds write in Google Chrome before 102.0.5005.125 on ChromeOS allows remote attackers to corrupt CRAS heap memory via audio metadata. The CRAS cras_bt_player_update_identity function copies the unbounded SetPlayerIdentity string into a 128-byte heap buffer with strcpy. Playback in the browser or from a paired Bluetooth device can supply the metadata; a crash is direct, while code execution requires heap grooming and another flaw.
