What is CVE-2026-92695?

FastNetMon, a high-performance DDoS detection tool, has a vulnerability that affects versions 1.2.9 and earlier. The live parse_packet() callback, which is executed when pcap is enabled, fails to validate the length of the captured frames properly. This oversight can allow an attacker to exploit the software by crafting a short frame or manipulating the IPv4 header length, potentially leading to an out-of-bounds read. This could result in reading beyond allocated memory or unexpected process termination, posing significant security risks.

Affected Version(s)

fastnetmon <= 1.2.9
