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-2026-98172 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-2026-98172/ (Markdown: https://insights.sbomify.com/CVE-2026-98172/index.md)","id":"CVE-2026-98172","markdown":"https://insights.sbomify.com/CVE-2026-98172/index.md","name":"CVE-2026-98172","record":{"aliases":["AZL-106104","BELL-CVE-2026-98172","DEBIAN-CVE-2026-98172","GHSA-h5hv-w97x-4565","UBUNTU-CVE-2026-98172"],"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 memory leak in the Linux kernel SMB client allows remote attackers to cause denial of service by triggering connection errors.","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: client: fix smbd_connection leak on cifs_get_tcp_session() error\n\nWhen an RDMA connection is successfully established via\nsmbd_get_connection() but cifs_get_tcp_session() later fails (e.g.\nkthread_create() returns an error), the error path frees tcp_ses\nwithout first destroying the smbd_connection.\n\nFix this by calling smbd_destroy() in the out_err cleanup path before\nkfree(tcp_ses).  smbd_destroy() safely handles the case where\nsmbd_conn is NULL, so it can be called unconditionally.","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 smbd_connection leak on cifs_get_tcp_session() error","id":"CVE-2026-98172","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"smb: client: fix use-after-free of iface in cifs_try_adding_channels()","id":"CVE-2026-98173"},"packages":[],"prev":{"headline":"smb: client: fix next_buffer UAF and NextCommand bounds in compound PDUs","id":"CVE-2026-98171"},"products":["Linux"],"published":"2026-10-06","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":"2026-10-19","vendors":["Linux"]},"summary":"A memory leak in the Linux kernel SMB client allows remote attackers to cause denial of service by triggering connection errors.","url":"https://insights.sbomify.com/CVE-2026-98172/"}
