CVE-2019-5892 is a denial-of-service vulnerability affecting FRRouting (FRR) versions 2.x through 6.x, specifically when ENABLE_BGP_VNC is active. A remote attacker can trigger a BGP peering session flap by sending a BGP UPDATE packet containing attribute 255, which FRR incorrectly interprets as invalid VNC data due to non-compliance with RFC 7606. This vulnerability has a CVSS score of 6.5 (Medium), indicating it can be exploited remotely with low attack complexity to achieve high availability impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
