CVE-2025-69807Public exploitNetwork attack vector

Server crash via unchecked packet length

Published Feb 12, 2026 · Updated Feb 12, 2026

Buffer overflow in p2r3 Bareiron commit 8e4d4020d allows remote attackers to crash the server with a crafted network packet. handlePacket passes an unchecked, user-controlled packet length to recv_all, which writes beyond the global recv_buffer into adjacent memory. No authentication or user interaction is required; the documented consequence is a server crash rather than data disclosure or modification.
