CVE-2023-49142

Multimedia audio crash via released pointer modification

Published Jan 2, 2024 · Updated Jun 17, 2025

Use-after-free in OpenHarmony 3.2.0 through 3.2.2 allows local users to crash multimedia audio by modifying a released pointer. The published advisory identifies a released pointer as the memory-safety locus but does not disclose the affected function or the operation that permits its modification. Local execution is required, and the documented consequence is limited to interruption of multimedia audio rather than system-wide shutdown or data access.
