CVE-2025-40779: 1 source package rows (kea); 9 state rows across 3 repos (3.21-main, 3.22-main, edge-main); fixed 0, open 9.
If a DHCPv4 client sends a request with some specific options, and Kea fails to find an appropriate subnet for the client, the `kea-dhcp4` process will abort with an assertion failure. This happens only if the client request is unicast directly to Kea; broadcast messages do not cause the problem. This issue affects Kea versions 2.7.1 through 2.7.9, 3.0.0, and 3.1.0.
