{"id":"CVE-2026-16445","summary":"Dracut: dracut: root code execution via dhcp options command injection in networkmanager initrd module","details":"A flaw was found in dracut. A remote attacker on the adjacent network can exploit this vulnerability by providing specially crafted DHCP options, such as a malicious root-path, next-server, or bootfile name, to a system using dracut's NetworkManager-based initrd network module. These options are improperly handled and written into a temporary shell script without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs during system boot.","modified":"2026-07-24T03:57:05.293894251Z","published":"2026-07-21T12:51:08.650Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/16xxx/CVE-2026-16445.json","cna_assigner":"redhat","cwe_ids":["CWE-78"]},"references":[{"type":"WEB","url":"https://access.redhat.com/downloads/content/package-browser/"},{"type":"WEB","url":"https://catalog.redhat.com/software/containers/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:26534"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:40700"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-16445"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/16xxx/CVE-2026-16445.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-16445"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2459963"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2503147"},{"type":"FIX","url":"https://github.com/dracutdevs/dracut/commit/e509c638e6"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dracutdevs/dracut","events":[{"introduced":"0"},{"fixed":"e509c638e6"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-16445.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
