CVE-2025-70102
Published:June 15, 2026
Updated:June 29, 2026
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.
