It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-16445 in the wild and no public exploit code.\n\nAffected product: Red Hat Enterprise Linux 10. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-16445/ (Markdown: https://insights.sbomify.com/CVE-2026-16445/index.md)","id":"CVE-2026-16445","markdown":"https://insights.sbomify.com/CVE-2026-16445/index.md","name":"CVE-2026-16445","record":{"aliases":["DEBIAN-CVE-2026-16445","GHSA-4672-282m-8fgr","OESA-2026-3300","OESA-2026-3301","RHSA-2026:40700","UBUNTU-CVE-2026-16445","openSUSE-SU-2026:11657-1"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux initramfs tool","requires_auth":"none","summary":"Remote attackers can execute arbitrary root commands during boot via malicious DHCP options in dracut's NetworkManager initrd module.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"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.","ecosystems":["Red Hat:hummingbird:1","openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Dracut: dracut: root code execution via dhcp options command injection in networkmanager initrd module","id":"CVE-2026-16445","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":9,"n_references":10,"next":{"headline":"D-Link DNS-320 multi_uploadify.php unrestricted upload","id":"CVE-2026-16447"},"packages":[{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:109-7.hum1"],"introduced":["0"],"last_affected":[],"package":"dracut","purl":"pkg:rpm/redhat/dracut","source":"RHSA-2026:40700"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:109-7.hum1"],"introduced":["0"],"last_affected":[],"package":"dracut-caps","purl":"pkg:rpm/redhat/dracut-caps","source":"RHSA-2026:40700"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:109-7.hum1"],"introduced":["0"],"last_affected":[],"package":"dracut-config-generic","purl":"pkg:rpm/redhat/dracut-config-generic","source":"RHSA-2026:40700"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:109-7.hum1"],"introduced":["0"],"last_affected":[],"package":"dracut-config-rescue","purl":"pkg:rpm/redhat/dracut-config-rescue","source":"RHSA-2026:40700"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:109-7.hum1"],"introduced":["0"],"last_affected":[],"package":"dracut-live","purl":"pkg:rpm/redhat/dracut-live","source":"RHSA-2026:40700"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:109-7.hum1"],"introduced":["0"],"last_affected":[],"package":"dracut-network","purl":"pkg:rpm/redhat/dracut-network","source":"RHSA-2026:40700"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:109-7.hum1"],"introduced":["0"],"last_affected":[],"package":"dracut-squash","purl":"pkg:rpm/redhat/dracut-squash","source":"RHSA-2026:40700"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:109-7.hum1"],"introduced":["0"],"last_affected":[],"package":"dracut-tools","purl":"pkg:rpm/redhat/dracut-tools","source":"RHSA-2026:40700"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["112+suse.47.gec0b378-1.1"],"introduced":["0"],"last_affected":[],"package":"dracut","purl":"pkg:rpm/opensuse/dracut\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2026:11657-1"}],"prev":{"headline":"Improper Validation of File Paths in TeamViewer Desktop Clients","id":"CVE-2026-16444"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 6","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support","Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On","Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support","Red Hat Enterprise Linux 8.6 Extended Update Support Long-Life Add-On","Red Hat Enterprise Linux 8.8 Telecommunications Update Service","Red Hat Enterprise Linux 8.8 Update Services for SAP Solutions","Red Hat Enterprise Linux 9","Red Hat Hardened Images","Red Hat OpenShift Container Platform 4.12"],"published":"2026-07-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Red Hat","prefix":"RHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-27","vendors":["Red Hat"]},"summary":"Remote attackers can execute arbitrary root commands during boot via malicious DHCP options in dracut's NetworkManager initrd module.","url":"https://insights.sbomify.com/CVE-2026-16445/"}
