CVE-2026-88357Public exploitNetwork attack vector

Process crash via unaligned network-field pointer dereferences

Published Sep 24, 2026 · Updated Sep 24, 2026

Memory-alignment errors in nDPI 5.1.0 allow remote attackers to crash traffic-analysis processes via crafted DNS packets. The DNS get16 helper and serializer deserializers cast byte-buffer positions at odd offsets to uint16_t or wider pointers and dereference them directly. A crash requires the packet to reach an nDPI consumer built with trap-on-error undefined-behavior sanitization or running on a strict-alignment CPU; ordinary x86-64 builds do not fault natively.
