dhcpcd-6.8.2 predates several CVEs:

If your device faces untrusted networks, do not use 6.8.2 without backporting patches. However, for isolated industrial networks or home automation, the risk is minimal. The binary is not vulnerable to the more recent RCEs (like 2021’s construct_env issue in dhcpcd-9.x). dhcpcd-6.8.2-armv7l

Pro recommendation: If possible, compile 6.8.2 from source with -D_FORTIFY_SOURCE=2 and -O2 -fstack-protector-strong. # SysV init ln -s /etc/init
