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-2026-80726 in the wild and no public exploit code.\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-2026-80726/ (Markdown: https://insights.sbomify.com/CVE-2026-80726/index.md)","id":"CVE-2026-80726","markdown":"https://insights.sbomify.com/CVE-2026-80726/index.md","name":"CVE-2026-80726","record":{"aliases":["AZL-99062","BELL-CVE-2026-80726","DEBIAN-CVE-2026-80726","GHSA-j8gw-c9fh-xgv4","UBUNTU-CVE-2026-80726"],"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 KVM","requires_auth":"none","summary":"A use-after-free vulnerability in the Linux kernel's KVM MMU 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":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","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":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2026-80726","indexable":false,"kev":null,"kind":"cve_rejected","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":0,"next":{"headline":"x86/mce: Set up the polling timer before CMCI discovery","id":"CVE-2026-80727"},"packages":[],"prev":{"headline":"net: gro: properly validate BIG TCP aggregation criteria","id":"CVE-2026-80725"},"products":[],"published":"2026-09-03","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"REJECTED","updated":"2026-10-20","vendors":[]},"summary":"A use-after-free vulnerability in the Linux kernel's KVM MMU allows local attackers to potentially execute arbitrary code or escalate privileges.","url":"https://insights.sbomify.com/CVE-2026-80726/"}
