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-2026-74565 in the wild and no public exploit code.\n\nAffected product: 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-2026-74565/ (Markdown: https://insights.sbomify.com/CVE-2026-74565/index.md)","id":"CVE-2026-74565","markdown":"https://insights.sbomify.com/CVE-2026-74565/index.md","name":"CVE-2026-74565","record":{"aliases":["AZL-96509","BELL-CVE-2026-74565","DEBIAN-CVE-2026-74565","GHSA-x5cj-f9c8-r2x6","UBUNTU-CVE-2026-74565"],"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 vulnerability in the Linux kernel's netfilter subsystem allows local attackers to potentially execute arbitrary code or escalate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","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":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nf_tables: make nft_object rhltable per table\n\nThe nft_object rhltable is global, this allows for accessing objects\nthat are being dismangled from lookup path by other existing netns.\nGiven the nft_obj_destroy() releases the object inmediately, this might\nlead to use-after-free of these objects that are being released.\nMake the existing rhltable per table to address this issue to deal with\nwith the nft_rcv_nl_event() path too.\n\nUpdate nft_obj_lookup() to take the table as non-const, otherwise,\ncompiler complains when passing the objname_ht to rhltable_lookup().","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":"netfilter: nf_tables: make nft_object rhltable per table","id":"CVE-2026-74565","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"keys: make keyring key-chunk byte order agree with keyring_diff_objects()","id":"CVE-2026-74566"},"packages":[],"prev":{"headline":"netfilter: xt_hashlimit: validate hashtable supports XT_HASHLIMIT_RATE_MATCH","id":"CVE-2026-74564"},"products":["Linux"],"published":"2026-08-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-21","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel's netfilter subsystem allows local attackers to potentially execute arbitrary code or escalate privileges.","url":"https://insights.sbomify.com/CVE-2026-74565/"}
