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-2023-52441 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-2023-52441/ (Markdown: https://insights.sbomify.com/CVE-2023-52441/index.md)","id":"CVE-2023-52441","markdown":"https://insights.sbomify.com/CVE-2023-52441/index.md","name":"CVE-2023-52441","record":{"aliases":["BELL-CVE-2023-52441","CVE-2023-39178","DEBIAN-CVE-2023-52441","GHSA-x6xm-ghm9-28cr","UBUNTU-CVE-2023-52441"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"An out-of-bounds write in the Linux kernel ksmbd module allows attackers to cause memory corruption, potentially leading to code execution or system crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: fix out of bounds in init_smb2_rsp_hdr()\n\nIf client send smb2 negotiate request and then send smb1 negotiate\nrequest, init_smb2_rsp_hdr is called for smb1 negotiate request since\nneed_neg is set to false.
