Thanks to the OpenEmbedded community for the patches. This fixes the
following vulnerability:
- CVE-2026-29004:
BusyBox before commit 42202bf contains a heap buffer overflow
vulnerability in the DHCPv6 client (udhcpc6) DNS_SERVERS option
handler in networking/udhcp/d6_dhcpc.c that allows network-adjacent
attackers to trigger memory corruption by sending a crafted DHCPv6
response with a malformed D6_OPT_DNS_SERVERS option. Attackers can
exploit incorrect heap buffer allocation calculations in the
option_to_env() function to cause denial of service or achieve
arbitrary code execution on embedded systems without heap hardening.
