Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-90152 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-2026-90152/ (Markdown: https://insights.sbomify.com/CVE-2026-90152/index.md)","id":"CVE-2026-90152","markdown":"https://insights.sbomify.com/CVE-2026-90152/index.md","name":"CVE-2026-90152","record":{"aliases":["AZL-102975","BELL-CVE-2026-90152","DEBIAN-CVE-2026-90152","GHSA-c2gf-579m-pqr2","UBUNTU-CVE-2026-90152"],"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 session leak in the Linux kernel's ksmbd SMB server allows authenticated users to exhaust resources, causing denial of service.","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: fix session leak in ksmbd_session_register()\n\nSee the procedure below:\n\n  smb2_sess_setup\n    ksmbd_smb2_session_create\n      __session_create\n        atomic_set(\u0026sess-\u003erefcnt, 2)\n        hash_add(sessions_table, \u0026sess-\u003ehlist, sess-\u003eid)\n    ksmbd_session_register\n      xa_store(\u0026conn-\u003esessions, sess-\u003eid, sess) // fail\n    ksmbd_user_session_put\n      atomic_dec(\u0026sess-\u003erefcnt) // refcnt is 1, session is not freed\n\nRemove the session from sessions_table and drop its table reference if\nxa_store() fails.","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 session leak in ksmbd_session_register()","id":"CVE-2026-90152","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"ksmbd: bound smb_check_perm_dacl() ACE walks by DACL size","id":"CVE-2026-90153"},"packages":[],"prev":{"headline":"NFSv4: remove callback IDR entry on client allocation failure","id":"CVE-2026-90151"},"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 session leak in the Linux kernel's ksmbd SMB server allows authenticated users to exhaust resources, causing denial of service.","url":"https://insights.sbomify.com/CVE-2026-90152/"}
