CVE-2024-23709Network attack vector

Remote information disclosure via SoniVox buffer overruns

Published May 7, 2024 · Updated Oct 25, 2024

Heap buffer overflows in Google Android 12, 12L, 13, and 14 allow remote attackers to disclose device information through crafted media. SoniVox eas_wtengine applies gain without checking output-buffer limits, while eas_wtsynth fails to clip a calculated output length. Exploitation requires user interaction with attacker-controlled media; the published impact is information disclosure without added execution privileges.
