Summary
busybox security update
Details

The Swiss Army Knife of Embedded Linux

Security Fix(es):

BusyBox before commit 42202bf contains a heap buffer overflow vulnerability in the DHCPv6 client (udhcpc6) DNSSERVERS option handler in networking/udhcp/d6dhcpc.c that allows network-adjacent attackers to trigger memory corruption by sending a crafted DHCPv6 response with a malformed D6OPTDNSSERVERS option. Attackers can exploit incorrect heap buffer allocation calculations in the optionto_env() function to cause denial of service or achieve arbitrary code execution on embedded systems without heap hardening.(CVE-2026-29004)
