CVE-2019-6474 is a medium-severity vulnerability affecting Kea DHCP server versions 1.4.0 to 1.5.0, 1.6.0-beta1, and 1.6.0-beta2. It stems from a missing check on incoming client requests, allowing an attacker to introduce invalid leases into the server's storage. This can lead to a denial-of-service condition where the Kea server fails to restart if the number of invalid leases exceeds a hard-coded limit. The vulnerability has a CVSS score of 6.5 (MEDIUM) with an attack vector of Adjacent Network, low attack complexity, and high availability impact. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
