CVE-2026-92695: FastNetMon out-of-bounds read in pcap packet parser

CVE-2026-92695 · Severity: high · CVSS 8.2 · Published 2026-11-05

FastNetMon is a high-performance network traffic analyzer used to detect and mitigate DDoS attacks. When packet capture mode is enabled, the software crashes when processing truncated or malformed network frames without proper bounds checking. An attacker sending crafted packets across a monitored network segment causes denial of service and process termination.

Technologies: Pavel-Odintsov Fastnetmon. Vendors: Pavel-Odintsov.

Technical details

The parse_packet() callback in pcap_plugin/pcap_collector.cpp performs zero bounds checking against the actual captured frame length (packethdr->caplen). When processing IPv4 packets, an attacker-controlled IP header length field (IHL) combined with a short frame causes the parser to dereference IP and transport layer headers beyond the captured bytes, triggering an out-of-bounds read. This requires pcap mode enabled and network-accessible traffic on the monitored interface.
