CVE-2025-68382

Process crash via truncated NFS RPC messages

Published Dec 18, 2025 · Updated Dec 18, 2025

Out-of-bounds read in Elastic Packetbeat allows remote attackers to crash the process with truncated XDR-encoded NFS RPC messages. The NFS protocol dissector reads beyond the available message buffer when it parses a truncated XDR-encoded RPC message. The crafted traffic must reach an interface monitored by Packetbeat; no authentication or user interaction is required, and the reported effect is a reliable process crash.
