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-2015-8539 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-2015-8539/ (Markdown: https://insights.sbomify.com/CVE-2015-8539/index.md)","id":"CVE-2015-8539","markdown":"https://insights.sbomify.com/CVE-2015-8539/index.md","name":"CVE-2015-8539","record":{"aliases":["GHSA-6m9m-6qjp-9mm8","SUSE-SU-2016:0336-1","SUSE-SU-2016:0339-1","UBUNTU-CVE-2015-8539"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"Local attackers can gain privileges or cause denial of service via crafted keyctl commands in the Linux kernel KEYS subsystem.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"linux_kernel","vendor":"linux"},{"product":"linux_enterprise_real_time_extension","vendor":"suse"}],"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":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"The KEYS subsystem in the Linux kernel before 4.4 allows local users to gain privileges or cause a denial of service (BUG) via crafted keyctl commands that negatively instantiate a key, related to security/keys/encrypted-keys/encrypted.c, security/keys/trusted.c, and security/keys/user_defined.c.","ecosystems":["SUSE:Linux Enterprise Live Patching 12"],"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":"Privilege escalation in n/a","id":"CVE-2015-8539","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","linux:linux_kernel","suse:linux_enterprise_real_time_extension"],"type":"privilege_escalation","year":"2015"},"n_packages":2,"n_references":24,"next":{"headline":"Integer overflow in n/a","id":"CVE-2015-8540"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Live Patching 12","fixed":["2-2.1"],"introduced":["0"],"last_affected":[],"package":"kgraft-patch-SLE12-SP1_Update_1","purl":"pkg:rpm/suse/kgraft-patch-SLE12-SP1_Update_1\u0026distro=SUSE%20Linux%20Enterprise%20Live%20Patching%2012","source":"SUSE-SU-2016:0339-1"},{"ecosystem":"SUSE:Linux Enterprise Live Patching 12","fixed":["2-2.1"],"introduced":["0"],"last_affected":[],"package":"kgraft-patch-SLE12_Update_9","purl":"pkg:rpm/suse/kgraft-patch-SLE12_Update_9\u0026distro=SUSE%20Linux%20Enterprise%20Live%20Patching%2012","source":"SUSE-SU-2016:0336-1"}],"prev":{"headline":"Null dereference in n/a","id":"CVE-2015-8538"},"products":["n/a"],"published":"2016-02-08","related":[{"cvss_score":9.8,"headline":"SaltStack Salt Authentication Bypass","id":"CVE-2020-11651","kev_date_added":"2021-11-03","published":"2020-04-30"},{"cvss_score":9.8,"headline":"OpenSMTPD Remote Code Execution","id":"CVE-2020-7247","kev_date_added":"2022-03-25","published":"2020-01-29"},{"cvss_score":9.8,"headline":"Exim Out-of-bounds Write","id":"CVE-2019-16928","kev_date_added":"2022-03-03","published":"2019-09-27"},{"cvss_score":9.8,"headline":"Exim Buffer Overflow","id":"CVE-2018-6789","kev_date_added":"2021-11-03","published":"2018-02-08"},{"cvss_score":9.8,"headline":"Oracle Java SE and Java SE Embedded Remote Code Execution","id":"CVE-2015-2590","kev_date_added":"2022-03-03","published":"2015-07-16"},{"cvss_score":9.8,"headline":"Oracle JRE Remote Code Execution","id":"CVE-2013-0422","kev_date_added":"2022-05-25","published":"2013-01-10"},{"cvss_score":9.8,"headline":"Oracle Java SE Runtime Environment (JRE) Arbitrary Code Execution","id":"CVE-2011-3544","kev_date_added":"2022-03-03","published":"2011-10-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"SUSE"},{"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Local attackers can gain privileges or cause denial of service via crafted keyctl commands in the Linux kernel KEYS subsystem.","url":"https://insights.sbomify.com/CVE-2015-8539/"}
