## Description:

This update for kea fixes the following issues:

Update to 3.0.3:

  * CVE-2025-11232: invalid characters cause assert (bsc#1252863).
  * CVE-2026-3608: stack overflow via maliciously crafted message (bsc#1260380).

Changelog:

  * A large number of bracket pairs in a JSON payload directed to any endpoint
    would result in a stack overflow, due to recursive calls when parsing the
    JSON. This has been fixed. (CVE-2026-3608) [bsc#1260380]
  * When a hostname or FQDN received from a client is reduced to an empty string
    by hostname sanitizing, kea-dhcp4 and kea-dhcp6 will now drop the option.
    (CVE-2025-11232) [bsc#1252863]
  * A null dereference is now no longer possible when configuring the Control
    Agent with a socket that lacks the mandatory socket-name entry.
  * UNIX sockets are now created as group-writable.
  * Removed logging an error in ping check hook library if using lease cache
    treshold.
  * Fixed deadlock in ping-check hooks library.
  * Fixed a data race in ping-check hooks library.
