Memory corruption via oversized audio input buffer
Published May 6, 2024 · Updated Aug 1, 2024
Buffer overflow in Qualcomm Snapdragon Audio allows remote attackers to corrupt memory when a large-input audio file is played. The closed-source Audio component copies an oversized input buffer without validating its size, overrunning the destination buffer. No privileges or user interaction are required, but Qualcomm has not disclosed whether the corruption causes a crash, data access, or code execution.
