It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-90163 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-2026-90163/ (Markdown: https://insights.sbomify.com/CVE-2026-90163/index.md)","id":"CVE-2026-90163","markdown":"https://insights.sbomify.com/CVE-2026-90163/index.md","name":"CVE-2026-90163","record":{"aliases":["DEBIAN-CVE-2026-90163","GHSA-vh5f-3q2h-6w9g","UBUNTU-CVE-2026-90163"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A memory leak in the Linux kernel SMB server module during initialization failure can lead to resource exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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: call ksmbd_proc_cleanup() on module init failure\n\nWhen a later initializer fails, the unwind chain releases resources\ncreated after procfs and then jumps directly to class_unregister().\nReturning an error from module_init() leaves the proc tree and its\nper-CPU counters allocated.","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: call ksmbd_proc_cleanup() on module init failure","id":"CVE-2026-90163","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"smb/server: abort initialization when proc setup fails","id":"CVE-2026-90164"},"packages":[],"prev":{"headline":"ksmbd: defer publishing granted locks to prevent UAF/double-free race","id":"CVE-2026-90162"},"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":"2026-10-19","vendors":["Linux"]},"summary":"A memory leak in the Linux kernel SMB server module during initialization failure can lead to resource exhaustion and denial of service.","url":"https://insights.sbomify.com/CVE-2026-90163/"}
