CVE-2025-62672Network attack vector

Unauthenticated daemon crash via unchecked packet allocation

Published Oct 19, 2025 · Updated Oct 19, 2025

Denial of service in rplay through 3.3.2 allows remote attackers to crash the audio daemon via unauthenticated packet data. The RPLAY_DATA branch in rplay_unpack uses packet-controlled rp->data_size for malloc without a limit or failure check, then memcpy writes through the result. No authentication or user action is needed to reach packet processing; the established impact is a daemon crash, not code execution or data access.
