NULL Pointer Dereference in dhcpcd Configuration Parser

Publication date: 2026-06-15

Last updated on: 2026-06-15

Assigner: MITRE

Description
A NULL pointer dereference occurs in Roy Marples NetworkConfiguration/dhcpcd 10.3.0 while parsing configuration options. In parse_option() (src/if-options.c:1886), the code performs a member access on a NULL pointer of type 'struct dhcp_opt' when an unexpected/invalid option token or parsing state causes the lookup to yield NULL. The instrumented fuzzing build reports 'runtime error: member access within null pointer of type struct dhcp_opt' and aborts.

Executive Summary

This vulnerability is a NULL pointer dereference in Roy Marples NetworkConfiguration/dhcpcd version 10.3.0. It occurs while parsing configuration options in the function parse_option() located in src/if-options.c at line 1886. The code attempts to access a member of a NULL pointer of type 'struct dhcp_opt' when an unexpected or invalid option token or parsing state causes the lookup to return NULL. This results in a runtime error and causes the program to abort.

Impact Analysis

The impact of this vulnerability is that it can cause the dhcpcd program to crash due to a NULL pointer dereference when parsing configuration options. This could lead to denial of service or disruption of network configuration services on affected systems.
