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-2025-9408 in the wild and no public exploit code.\n\nAffected product: zephyrproject-rtos Zephyr. 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-2025-9408/ (Markdown: https://insights.sbomify.com/CVE-2025-9408/index.md)","id":"CVE-2025-9408","markdown":"https://insights.sbomify.com/CVE-2025-9408/index.md","name":"CVE-2025-9408","record":{"aliases":["GHSA-3r6j-5mp3-75wr"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Zephyr RTOS","requires_auth":"none","summary":"A race condition in Zephyr RTOS system call entry allows malicious userspace processes to escalate privileges on Cortex M devices.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zephyr","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-270","name":"Privilege Context Switching Error"}],"description":"System call entry on Cortex M (and possibly R and A, but I think not) has a race which allows very practical privilege escalation for malicious userspace processes.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Userspace privilege escalation vulnerability on Cortex M","id":"CVE-2025-9408","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"lostvip-com ruoyi-go CommonController.go DownloadUpload path traversal","id":"CVE-2025-9409"},"packages":[],"prev":{"headline":"mtons mblog profile cross site scripting","id":"CVE-2025-9407"},"products":["Zephyr"],"published":"2025-11-11","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-13","vendors":["zephyrproject-rtos"]},"summary":"A race condition in Zephyr RTOS system call entry allows malicious userspace processes to escalate privileges on Cortex M devices.","url":"https://insights.sbomify.com/CVE-2025-9408/"}
