{"id":"DEBIAN-CVE-2025-70102","details":"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.","modified":"2026-09-01T20:05:58.015000058Z","published":"2026-06-15T20:16:24.827Z","upstream":["CVE-2025-70102"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-70102"}],"affected":[{"package":{"name":"dhcpcd","ecosystem":"Debian:13","purl":"pkg:deb/debian/dhcpcd?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:10.1.0-11+deb13u3"}]}],"versions":["1:10.1.0-11","1:10.1.0-11+deb13u1","1:10.1.0-11+deb13u2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-70102.json"}},{"package":{"name":"dhcpcd","ecosystem":"Debian:14","purl":"pkg:deb/debian/dhcpcd?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:10.3.1-1"}]}],"versions":["1:10.1.0-11","1:10.1.0-12","1:10.2.0-1","1:10.2.2-1","1:10.2.2-2","1:10.2.2-3","1:10.2.2-4","1:10.2.2-5","1:10.2.2-6","1:10.2.3-1","1:10.2.4-1","1:10.2.4-2","1:10.2.4-3","1:10.2.4-4","1:10.2.4-4~bpo13+1","1:10.3.0-1","1:10.3.0-2","1:10.3.0-2~bpo13+1","1:10.3.0-3","1:10.3.0-3~bpo13+1","1:10.3.0-4","1:10.3.0-5","1:10.3.0-6","1:10.3.0-7","1:10.3.0-7~bpo13+1","1:10.3.1-1~bpo13+1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-70102.json"}},{"package":{"name":"dhcpcd5","ecosystem":"Debian:12","purl":"pkg:deb/debian/dhcpcd5?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.4.1-24~deb12u5"}]}],"versions":["9.4.1-22","9.4.1-23","9.4.1-24~deb12u1","9.4.1-24~deb12u2","9.4.1-24~deb12u3","9.4.1-24~deb12u4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-70102.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L"}]}
