CVE-2022-25686Network attack vector

Memory corruption via unchecked WAV buffer copy

Published Sep 16, 2022 · Updated Aug 3, 2024

Buffer overflow in Qualcomm Snapdragon video modules allows remote attackers to corrupt memory by supplying a crafted WAV file. The video module copies attacker-controlled WAV input without verifying that it fits the destination buffer. No authentication or user interaction is required, and successful exploitation can disclose or alter data or interrupt service.
