CVE-2026-121944

Versions of sngrep through 1.9.0 are vulnerable to an infinite loop vulnerability located in the capture_packet_reasm_ip() function within src/capture.c. An attacker can trigger a denial of service (DoS) by providing a pcap file with a link type of NFLOG that contains a non-payload TLV with a len...

CVE-2026-121944 sngrep through 1.9.0 Infinite Loop DoS via Crafted NFLOG TLV

sngrep through 1.9.0 contains an infinite loop vulnerability in capturepacketreasmip in src/capture.c that allows attackers to cause denial of service via crafted NFLOG TLVs. Attackers can supply a pcap file with link type NFLOG containing a non-payload TLV with length under 4, making the capture...
