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-2026-93829 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-2026-93829/ (Markdown: https://insights.sbomify.com/CVE-2026-93829/index.md)","id":"CVE-2026-93829","markdown":"https://insights.sbomify.com/CVE-2026-93829/index.md","name":"CVE-2026-93829","record":{"aliases":["AZL-103769","BELL-CVE-2026-93829","DEBIAN-CVE-2026-93829","GHSA-v43p-8x6p-65w4","UBUNTU-CVE-2026-93829"],"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 race condition in the Linux kernel SMB client allows remote attackers to cause a denial of service by triggering a thread synchronization error.","user_interaction":"not_required","vuln_class":"race_condition"},"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 races in cifsd thread creation\n\nThe cifsd demultiplex thread can run and access tcp_ses before the parent\nthread has finished populating tcp_ses, which the worker thread accesses\nlocklessly.\n\nAlso, the kthread_run macro may start the thread before returning the\nthread pointer.
