CVE-2025-12205 describes a use-after-free vulnerability in Kamailio 5.5's Configuration File Handler, specifically within the sr_push_yy_state function. This high-severity flaw (CVSS 7.8) requires local access and manipulation of configuration files, leading to potential high impact on confidentiality, integrity, and availability. While public exploit code exists, its practical applicability is debated due to the prerequisite of config file modification, and there is no evidence of active exploitation.
