An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-98174 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-2026-98174/ (Markdown: https://insights.sbomify.com/CVE-2026-98174/index.md)","id":"CVE-2026-98174","markdown":"https://insights.sbomify.com/CVE-2026-98174/index.md","name":"CVE-2026-98174","record":{"aliases":["AZL-106391","BELL-CVE-2026-98174","DEBIAN-CVE-2026-98174","GHSA-f559-3m6w-qcp7","UBUNTU-CVE-2026-98174"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel SMB client","requires_auth":"none","summary":"A race condition and missing initialization in the Linux kernel SMB client can lead to list corruption and potential denial of service.","user_interaction":"required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: fix rlist race and missing initialization\n\nTCP_Server_Info.rlist is allocated via kzalloc which zeros both -\u003enext\nand -\u003eprev to NULL instead of pointing to itself, making list_empty()\nalways return false and list_add() dereference a NULL -\u003eprev pointer.\n\nAlso, cifs_signal_cifsd_for_reconnect() can be called concurrently\nfrom multiple cifsd threads, allowing the same server's rlist node to\nbe added twice into the local list, corrupting it.","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: client: fix rlist race and missing initialization","id":"CVE-2026-98174","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"smb: client: cancel reconnect work in clean_demultiplex_info()","id":"CVE-2026-98175"},"packages":[],"prev":{"headline":"smb: client: fix use-after-free of iface in cifs_try_adding_channels()","id":"CVE-2026-98173"},"products":["Linux"],"published":"2026-10-06","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A race condition and missing initialization in the Linux kernel SMB client can lead to list corruption and potential denial of service.","url":"https://insights.sbomify.com/CVE-2026-98174/"}
