Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-90166 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-2026-90166/ (Markdown: https://insights.sbomify.com/CVE-2026-90166/index.md)","id":"CVE-2026-90166","markdown":"https://insights.sbomify.com/CVE-2026-90166/index.md","name":"CVE-2026-90166","record":{"aliases":["AZL-102218","BELL-CVE-2026-90166","DEBIAN-CVE-2026-90166","GHSA-72gq-5j57-9667","UBUNTU-CVE-2026-90166"],"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":"A null pointer dereference in the Linux kernel's ksmbd SMB server allows a low-privileged user to cause a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"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: fix null-ptr-deref in ksmbd_ipc_tree_connect_request()\n\nSee the procedure below:\n\n  ksmbd_tree_conn_connect\n    ksmbd_share_config_get\n      share-\u003ename = kstrdup() // fail\n      if (!test_share_config_flag(share, KSMBD_SHARE_FLAG_PIPE)) // false\n      // do not check `share-\u003ename`\n    ksmbd_ipc_tree_connect_request\n      strlen(share-\u003ename) // null-ptr-deref","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: fix null-ptr-deref in ksmbd_ipc_tree_connect_request()","id":"CVE-2026-90166","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"ksmbd: serialize oplock close with pending break ownership","id":"CVE-2026-90167"},"packages":[],"prev":{"headline":"smb/server: fix invalid pointer dereference in ksmbd_stop_durable_scavenger()","id":"CVE-2026-90165"},"products":["Linux"],"published":"2026-09-17","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":"2026-10-21","vendors":["Linux"]},"summary":"A null pointer dereference in the Linux kernel's ksmbd SMB server allows a low-privileged user to cause a denial of service.","url":"https://insights.sbomify.com/CVE-2026-90166/"}
