CVE-2025-70102

Process crash via unchecked option lookup

Published Jun 15, 2026 · Updated Jun 15, 2026

NULL pointer dereference in dhcpcd 10.3.0 allows attackers to crash the process by supplying an invalid configuration option. The parse_option() function dereferences a struct dhcp_opt pointer after an option lookup returns NULL for an unexpected token or parser state. Exploitation requires influence over configuration input; published evidence demonstrates an instrumented-build abort but does not establish remote reachability or a persistent service outage.
