An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-80877 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-2026-80877/ (Markdown: https://insights.sbomify.com/CVE-2026-80877/index.md)","id":"CVE-2026-80877","markdown":"https://insights.sbomify.com/CVE-2026-80877/index.md","name":"CVE-2026-80877","record":{"aliases":["BELL-CVE-2026-80877","DEBIAN-CVE-2026-80877","GHSA-phph-62rf-vgjm","UBUNTU-CVE-2026-80877"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A memory leak in the Linux kernel's AFS filesystem allows attackers to cause a denial of service by exhausting system memory.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nafs: Fix vllist leak\n\nFix a leak of the new vllist in afs_update_cell() in the event that it is an\nempty list (nr_servers == 0), in which case the old list isn't displaced\nunless the old list is also empty.","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":"afs: Fix vllist leak","id":"CVE-2026-80877","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"afs: Fix leak of ungot volume","id":"CVE-2026-80878"},"packages":[],"prev":{"headline":"ring-buffer: Fix event length with forced 8-byte alignment","id":"CVE-2026-80876"},"products":["Linux"],"published":"2026-09-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-09-04","vendors":["Linux"]},"summary":"A memory leak in the Linux kernel's AFS filesystem allows attackers to cause a denial of service by exhausting system memory.","url":"https://insights.sbomify.com/CVE-2026-80877/"}
