Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-98439 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-2026-98439/ (Markdown: https://insights.sbomify.com/CVE-2026-98439/index.md)","id":"CVE-2026-98439","markdown":"https://insights.sbomify.com/CVE-2026-98439/index.md","name":"CVE-2026-98439","record":{"aliases":["AZL-109275","BELL-CVE-2026-98439","DEBIAN-CVE-2026-98439","GHSA-xm6x-r8m7-4r79","UBUNTU-CVE-2026-98439"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel SMB server","requires_auth":"low_privilege","summary":"An attacker can cause a denial of service by preventing SMB connections from closing properly due to uncancelled async requests.","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\nsmb/server: cancel async requests when closing connection\n\nAn async request may still be waiting when a connection is closed.\nThis can stop the connection from closing.\n\nCancel active async requests before waiting for them to finish.","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":"smb/server: cancel async requests when closing connection","id":"CVE-2026-98439","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"KVM: arm64: nv: Delay freeing of shadow S2 structures until VM destruction","id":"CVE-2026-98440"},"packages":[],"prev":{"headline":"mptcp: options: fix uninit-value in mptcp_write_data_fin","id":"CVE-2026-98438"},"products":["Linux"],"published":"2026-10-18","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":"2026-10-26","vendors":["Linux"]},"summary":"An attacker can cause a denial of service by preventing SMB connections from closing properly due to uncancelled async requests.","url":"https://insights.sbomify.com/CVE-2026-98439/"}
