It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2015-8660 exists.\n\nAffected product: Linux kernel. 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-2015-8660/ (Markdown: https://insights.sbomify.com/CVE-2015-8660/index.md)","id":"CVE-2015-8660","markdown":"https://insights.sbomify.com/CVE-2015-8660/index.md","name":"CVE-2015-8660","record":{"aliases":["DEBIAN-CVE-2015-8660","GHSA-2m7p-qcqr-gfv2","UBUNTU-CVE-2015-8660","USN-2857-2","USN-2858-2"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_modify","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"high_privilege","summary":"Local attackers can bypass access restrictions to modify attributes of arbitrary overlay files in the Linux kernel.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":6.7,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-264","name":null}],"description":"The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel through 4.3.3 attempts to merge distinct setattr operations, which allows local users to bypass intended access restrictions and modify the attributes of arbitrary overlay files via a crafted application.","ecosystems":[],"exploits":{"exploitdb":3,"first_seen":"2015-06-16","github_poc":3,"max_poc_stars":3,"metasploit":1,"nuclei":0,"refs":[{"date":"2016-04-14T15:09:19Z","kind":"github_poc","ref":"https://github.com/whu-enjoy/CVE-2015-8660","stars":3,"title":"这个代码包含了CVE-2015-8660漏洞的利用代码，还有注释，出现问题的源代码，打了补丁后的代码"},{"date":"2015-06-16","kind":"metasploit","ref":"exploit/linux/local/overlayfs_priv_esc","stars":null,"title":"Overlayfs Privilege Escalation"},{"date":"2016-01-05","kind":"exploitdb","ref":"39166","stars":null,"title":"Linux Kernel 4.3.3 (Ubuntu 14.04/15.10) - 'overlayfs' Local Privilege Escalation (1)"},{"date":"2016-01-12","kind":"exploitdb","ref":"39230","stars":null,"title":"Linux Kernel 4.3.3 - 'overlayfs' Local Privilege Escalation (2)"},{"date":"2016-11-02","kind":"exploitdb","ref":"40688","stars":null,"title":"Linux Kernel (Ubuntu / Fedora / RedHat) - 'Overlayfs' Local Privilege Escalation (Metasploit)"},{"date":"2023-01-15T02:35:52Z","kind":"github_poc","ref":"https://github.com/nhamle2/CVE-2015-8660","stars":0,"title":null},{"date":"2024-09-10T14:05:57Z","kind":"github_poc","ref":"https://github.com/carradolly/CVE-2015-8660","stars":0,"title":null}],"tier":"weaponised"},"has_fix":true,"headline":"Missing authorization in n/a","id":"CVE-2015-8660","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"missing_authorization","year":"2015"},"n_packages":0,"n_references":23,"next":{"headline":"Memory corruption in n/a","id":"CVE-2015-8661"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2015-8659"},"products":["n/a"],"published":"2015-12-28","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Local attackers can bypass access restrictions to modify attributes of arbitrary overlay files in the Linux kernel.","url":"https://insights.sbomify.com/CVE-2015-8660/"}
