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-2016-2568 in the wild and no public exploit code.\n\nAffected product: Redhat Enterprise 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-2016-2568/ (Markdown: https://insights.sbomify.com/CVE-2016-2568/index.md)","id":"CVE-2016-2568","markdown":"https://insights.sbomify.com/CVE-2016-2568/index.md","name":"CVE-2016-2568","record":{"aliases":["AZL-35109","AZL-6800","DEBIAN-CVE-2016-2568","GHSA-8vgc-x7hv-3g84","UBUNTU-CVE-2016-2568"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux pkexec utility","requires_auth":"low_privilege","summary":"Local attackers can escalate privileges to the parent session by exploiting a TIOCSTI ioctl vulnerability in the pkexec utility.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"polkit","vendor":"freedesktop"},{"product":"enterprise_linux","vendor":"redhat"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"pkexec, when used with --user nonpriv, allows local users to escape to the parent session via a crafted TIOCSTI ioctl call, which pushes characters to the terminal's input buffer.","ecosystems":[],"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-2016-2568","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"redhat:enterprise_linux","products":["redhat:enterprise_linux"],"type":"privilege_escalation","year":"2016"},"n_packages":0,"n_references":5,"next":{"headline":"Denial of service in n/a","id":"CVE-2016-2569"},"packages":[],"prev":{"headline":"Security feature bypass in n/a","id":"CVE-2016-2567"},"products":["n/a"],"published":"2017-02-13","related":[{"cvss_score":5.5,"headline":"Polkit: polkit: denial of service via unbounded input processing through standard input","id":"CVE-2026-4897","kev_date_added":null,"published":"2026-03-26"}],"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)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-08","vendors":["n/a"]},"summary":"Local attackers can escalate privileges to the parent session by exploiting a TIOCSTI ioctl vulnerability in the pkexec utility.","url":"https://insights.sbomify.com/CVE-2016-2568/"}
