| CVE-2025-32801 | Hig | 0.51 | 7.8 | 0.00 | May 28, 2025 | Kea configuration and API directives can be used to load a malicious hook library. Many common configurations run Kea as root, leave the API entry points unsecured by default, and/or place the control sockets in insecure paths. This issue affects Kea versions 2.4.0 through… | ||
| CVE-2025-11232 | Hig | 0.49 | 7.5 | 0.00 | Oct 29, 2025 | To trigger the issue, three configuration parameters must have specific settings: "hostname-char-set" must be left at the default setting, which is "[^A-Za-z0-9.-]"; "hostname-char-replacement" must be empty (the default); and "ddns-qualifying-suffix" must *NOT* be empty (the… | ||
| CVE-2025-40779 | Hig | 0.49 | 7.5 | 0.01 | Aug 27, 2025 | 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… | ||
| CVE-2015-8373 | Med | 0.44 | 6.8 | 0.04 | Dec 22, 2015 | The kea-dhcp4 and kea-dhcp6 servers 0.9.2 and 1.0.0-beta in ISC Kea, when certain debugging settings are used, allow remote attackers to cause a denial of service (daemon crash) via a malformed packet. | ||
| CVE-2025-32802 | Med | 0.40 | 6.1 | 0.00 | May 28, 2025 | Kea configuration and API directives can be used to overwrite arbitrary files, subject to permissions granted to Kea. Many common configurations run Kea as root, leave the API entry points unsecured by default, and/or place the control sockets in insecure paths. This issue… | ||
| CVE-2025-32803 | Med | 0.26 | 4.0 | 0.00 | May 28, 2025 | In some cases, Kea log files or lease files may be world-readable. This issue affects Kea versions 2.4.0 through 2.4.1, 2.6.0 through 2.6.2, and 2.7.0 through 2.7.8. | ||
| CVE-2026-3608 | 0.00 | — | 0.01 | Mar 25, 2026 | Sending a maliciously crafted message to the kea-ctrl-agent, kea-dhcp-ddns, kea-dhcp4, or kea-dhcp6 daemons over any configured API socket or HA listener can cause the receiving daemon to exit with a stack overflow error. This issue affects Kea versions 2.6.0 through 2.6.4 and… | |||
| CVE-2019-6474 | 0.00 | — | 0.01 | Oct 16, 2019 | A missing check on incoming client requests can be exploited to cause a situation where the Kea server's lease storage contains leases which are rejected as invalid when the server tries to load leases from storage on restart. If the number of such leases exceeds a hard-coded… | |||
| CVE-2019-6473 | 0.00 | — | 0.01 | Oct 16, 2019 | An invalid hostname option can trigger an assertion failure in the Kea DHCPv4 server process (kea-dhcp4), causing the server process to exit. Versions affected: 1.4.0 to 1.5.0, 1.6.0-beta1, and 1.6.0-beta2. | |||
| CVE-2019-6472 | 0.00 | — | 0.01 | Oct 16, 2019 | A packet containing a malformed DUID can cause the Kea DHCPv6 server process (kea-dhcp6) to exit due to an assertion failure. Versions affected: 1.4.0 to 1.5.0, 1.6.0-beta1, and 1.6.0-beta2. | |||
| CVE-2018-5739 | 0.00 | — | 0.02 | Jan 16, 2019 | An extension to hooks capabilities which debuted in Kea 1.4.0 introduced a memory leak for operators who are using certain hooks library facilities.
