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).

  • 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.
