It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2022-2586 in the wild since at least 26 Jun 2024.\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-2022-2586/ (Markdown: https://insights.sbomify.com/CVE-2022-2586/index.md)","id":"CVE-2022-2586","markdown":"https://insights.sbomify.com/CVE-2022-2586/index.md","name":"CVE-2022-2586","record":{"aliases":["AZL-33260","DEBIAN-CVE-2022-2586","UBUNTU-CVE-2022-2586"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A use-after-free in the Linux kernel nftables subsystem allows local attackers to potentially execute code or escalate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"linux_kernel","vendor":"linux"},{"product":"simatic_s7-1500_tm_mfp_firmware","vendor":"siemens"},{"product":"sinec_os","vendor":"siemens"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"It was discovered that a nft object or expression could reference a nft set on a different nft table, leading to a use-after-free once that table was deleted.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2022-09-03","github_poc":3,"max_poc_stars":22,"metasploit":0,"nuclei":0,"refs":[{"date":"2022-09-03T19:04:31Z","kind":"github_poc","ref":"https://github.com/aels/CVE-2022-2586-LPE","stars":22,"title":"CVE-2022-2586: Linux kernel nft_object UAF"},{"date":"2022-11-06T07:34:32Z","kind":"github_poc","ref":"https://github.com/sniper404ghostxploit/CVE-2022-2586","stars":2,"title":"gcc exploit.c -o exploit -lmnl -lnftnl -no-pie -lpthread"},{"date":"2023-06-15T07:04:05Z","kind":"github_poc","ref":"https://github.com/lanleft/CVE-2022-2586","stars":0,"title":null}],"tier":"exploited"},"has_fix":true,"headline":"Linux Kernel Use-After-Free","id":"CVE-2022-2586","indexable":true,"kev":{"dateAdded":"2024-06-26","dueDate":"2024-07-17","knownRansomwareCampaignUse":"Unknown","product":"Kernel","requiredAction":"Apply updates per vendor instructions or discontinue use of the product if updates are unavailable.","vendorProject":"Linux","vulnerabilityName":"Linux Kernel Use-After-Free Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","linux:linux_kernel"],"type":"use_after_free","year":"2022"},"n_packages":0,"n_references":13,"next":{"headline":"Memory corruption in Chrome","id":"CVE-2022-2587"},"packages":[],"prev":{"headline":"Use after free in linux","id":"CVE-2022-2585"},"products":["linux"],"published":"2024-01-08","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":"US public information, NVD API terms","name":"NVD"},{"class":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-14","vendors":["The Linux Kernel Organization"]},"summary":"A use-after-free in the Linux kernel nftables subsystem allows local attackers to potentially execute code or escalate privileges.","url":"https://insights.sbomify.com/CVE-2022-2586/"}
