CVE-2026-92695

Name of the Vulnerable Software and Affected Versions FastNetMon versions prior to 1.2.10

Description The parse packet() function in src/pcap plugin/pcap collector.cpp fails to verify packethdr->caplen when processing captured frames via pcap loop while pcap is enabled. An attacker can trigger an out-of-bounds read—where the system reads data outside the intended memory boundary—by sending a short frame or a manipulated IPv4 header length. This leads to the dereferencing of IP or transport headers beyond the captured bytes, resulting in process termination.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
