CVE-2025-62170Network attack vector

Map-server crash via unchecked RODEX inventory index

Published Oct 13, 2025 · Updated Oct 27, 2025

Use-after-free in rAthena map-server before af2f3ba allows remote attackers to crash the service through RODEX mail handling. The clif_mail_removeitem function uses a RODEX mail item index to dereference sd->inventory_data without validating its range or checking for a null item_data pointer. No authentication or user interaction is required, and exploitation interrupts gameplay by terminating the map-server process.
