Hi,
The following vulnerability was published for busybox.
CVE-2026-29004[0]:
| 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.

This has been fixed in upstream 1.38.0 release. Apparently I forgot to
close this bug report. Doing this now.
This can be fixed for trixie, too.
Thanks,
