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-2016-1576 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu 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-2016-1576/ (Markdown: https://insights.sbomify.com/CVE-2016-1576/index.md)","id":"CVE-2016-1576","markdown":"https://insights.sbomify.com/CVE-2016-1576/index.md","name":"CVE-2016-1576","record":{"aliases":["DEBIAN-CVE-2016-1576","GHSA-6774-jh98-f2hq","UBUNTU-CVE-2016-1576"],"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":"Local attackers can gain privileges by exploiting overlayfs mount namespace restrictions to execute crafted setuid programs.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"ubuntu_core","vendor":"canonical"},{"product":"ubuntu_linux","vendor":"canonical"},{"product":"ubuntu_touch","vendor":"canonical"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","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":"The overlayfs implementation in the Linux kernel through 4.5.2 does not properly restrict the mount namespace, which allows local users to gain privileges by mounting an overlayfs filesystem on top of a FUSE filesystem, and then executing a crafted setuid program.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2016-11-22","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2016-11-22","kind":"exploitdb","ref":"41763","stars":null,"title":"Ubuntu 15.10 - 'USERNS ' Overlayfs Over Fuse Privilege Escalation"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Privilege escalation in n/a","id":"CVE-2016-1576","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","linux:linux_kernel"],"type":"privilege_escalation","year":"2016"},"n_packages":0,"n_references":8,"next":{"headline":"Use after free in n/a","id":"CVE-2016-1577"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2016-1575"},"products":["n/a"],"published":"2016-05-02","related":[{"cvss_score":7.8,"headline":"Privilege escalation in n/a","id":"CVE-2016-1575","kev_date_added":null,"published":"2016-05-02"},{"cvss_score":7.8,"headline":"Privilege escalation in n/a","id":"CVE-2015-8325","kev_date_added":null,"published":"2016-05-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Local attackers can gain privileges by exploiting overlayfs mount namespace restrictions to execute crafted setuid programs.","url":"https://insights.sbomify.com/CVE-2016-1576/"}
