{"id":"UBUNTU-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":"2026-06-24T08:58:14Z","published":"2026-06-15T20:16:00Z","upstream":["CVE-2025-70102"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-70102"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-70102"},{"type":"REPORT","url":"https://github.com/NetworkConfiguration/dhcpcd/issues/567"},{"type":"REPORT","url":"https://infosec.exchange/@sigdevel/116733594508542047"}],"affected":[{"package":{"name":"dhcpcd","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/dhcpcd?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:10.0.2-3ubuntu3","1:10.0.5-1","1:10.0.5-2","1:10.0.5-3","1:10.0.5-4","1:10.0.5-5","1:10.0.6-1","1:10.0.6-1ubuntu1","1:10.0.6-1ubuntu2","1:10.0.6-1ubuntu3","1:10.0.6-1ubuntu3.1","1:10.0.6-1ubuntu3.2"],"ecosystem_specific":{"binaries":[{"binary_version":"1:10.0.6-1ubuntu3.2","binary_name":"dhcpcd"},{"binary_name":"dhcpcd-base","binary_version":"1:10.0.6-1ubuntu3.2"},{"binary_name":"dhcpcd5","binary_version":"1:10.0.6-1ubuntu3.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-70102.json"}},{"package":{"name":"dhcpcd","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/dhcpcd?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:10.1.0-8","1:10.1.0-10","1:10.1.0-11","1:10.1.0-12","1:10.2.4-3","1:10.2.4-4"],"ecosystem_specific":{"binaries":[{"binary_version":"1:10.2.4-4","binary_name":"dhcpcd"},{"binary_name":"dhcpcd-base","binary_version":"1:10.2.4-4"},{"binary_name":"dhcpcd5","binary_version":"1:10.2.4-4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-70102.json"}},{"package":{"name":"dhcpcd","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/dhcpcd?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:10.2.4-4","1:10.3.0-2","1:10.3.0-3","1:10.3.0-7"],"ecosystem_specific":{"binaries":[{"binary_name":"dhcpcd","binary_version":"1:10.3.0-7"},{"binary_name":"dhcpcd-base","binary_version":"1:10.3.0-7"},{"binary_name":"dhcpcd5","binary_version":"1:10.3.0-7"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-70102.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L"},{"type":"Ubuntu","score":"medium"}]}
