Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-1193 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2023-1193/ (Markdown: https://insights.sbomify.com/CVE-2023-1193/index.md)","id":"CVE-2023-1193","markdown":"https://insights.sbomify.com/CVE-2023-1193/index.md","name":"CVE-2023-1193","record":{"aliases":["AZL-31813","AZL-31851","DEBIAN-CVE-2023-1193","GHSA-vv37-54q4-33cj","OESA-2023-1888","OESA-2023-1889","OESA-2023-1890","ROOT-OS-UBUNTU-2204-CVE-2023-1193","ROOT-OS-UBUNTU-2404-CVE-2023-1193","UBUNTU-CVE-2023-1193"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel KSMBD","requires_auth":"low_privilege","summary":"An attacker can crash the Linux kernel by triggering a use-after-free in the KSMBD server implementation.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"A use-after-free flaw was found in setup_async_work in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel.
