CVE-2026-88357: Incorrect Bitwise Shift of Integer

nDPI 5.1.0 contains a memory access issue in the DNS dissector and serializer deserialization code. Specially crafted network input can cause byte-buffer addresses at odd offsets to be cast to uint16t or wider integer pointers and directly dereferenced without alignment checks. This results in...
