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-2026-90164 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-2026-90164/ (Markdown: https://insights.sbomify.com/CVE-2026-90164/index.md)","id":"CVE-2026-90164","markdown":"https://insights.sbomify.com/CVE-2026-90164/index.md","name":"CVE-2026-90164","record":{"aliases":["DEBIAN-CVE-2026-90164","GHSA-6gqw-gw67-f4rg","UBUNTU-CVE-2026-90164"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel SMB server","requires_auth":"none","summary":"A null pointer dereference in the Linux kernel SMB server can cause a denial of service when proc setup fails during initialization.","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: abort initialization when proc setup fails\n\nksmbd_server_init() calls ksmbd_proc_init() before creating the\nremaining proc entries and server subsystems. ksmbd_proc_init() tears\ndown partial state on a procfs or percpu_counter allocation failure,\nbut returns void, so ksmbd_server_init() continues as if the counters\nwere usable.\n\nOnce userspace starts the server, server_ctrl_handle_init() calls\nksmbd_proc_reset(), which reaches percpu_counter_set() with a NULL\nper-CPU counters pointer on SMP systems.
