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-2025-38499 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2025-38499/ (Markdown: https://insights.sbomify.com/CVE-2025-38499/index.md)","id":"CVE-2025-38499","markdown":"https://insights.sbomify.com/CVE-2025-38499/index.md","name":"CVE-2025-38499","record":{"aliases":["AZL-66174","AZL-73470","BELL-CVE-2025-38499","DEBIAN-CVE-2025-38499","GHSA-cc85-5h45-qhc8","RHSA-2025:23730","ROOT-OS-DEBIAN-11-CVE-2025-38499","ROOT-OS-DEBIAN-12-CVE-2025-38499","ROOT-OS-UBUNTU-2204-CVE-2025-38499","ROOT-OS-UBUNTU-2404-CVE-2025-38499","UBUNTU-CVE-2025-38499"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A missing capability check in the Linux kernel allows local attackers to escalate privileges by cloning private mounts without proper user namespace authorization.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nclone_private_mnt(): make sure that caller has CAP_SYS_ADMIN in the right userns\n\nWhat we want is to verify there is that clone won't expose something\nhidden by a mount we wouldn't be able to undo.  \"Wouldn't be able to undo\"\nmay be a result of MNT_LOCKED on a child, but it may also come from\nlacking admin rights in the userns of the namespace mount belongs to.\n\nclone_private_mnt() checks the former, but not the latter.\n\nThere's a number of rather confusing CAP_SYS_ADMIN checks in various\nuserns during the mount, especially with the new mount API;
