ndpi: CVE-2026-116744

Severity: Medium
Published: Oct 26, 2026, 10:16:58 PM UTC
Source: [NVD] · [CVE record]

ntop nDPI through 6.0 contains an out-of-bounds read vulnerability in dissect_softether_host_fqdn() in softether.c that compares host_name using the consumed byte count instead of data length. Remote attackers can send crafted short UDP datagrams on already-classified SoftEther flows, causing strncmp to read beyond the packet payload buffer.
