CVE-2026-63449
Description
A flaw was found in Suricata, a network Intrusion Detection System (IDS) and Intrusion Prevention System (IPS). The Session Initiation Protocol (SIP) parser incorrectly handles large SIP message bodies. When a SIP message body exceeds 65,536 bytes, the parser truncates its length, preventing the full content from being inspected. This allows malicious content within the uninspected portion of the message to evade detection by the system.
