An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-53676 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-2023-53676/ (Markdown: https://insights.sbomify.com/CVE-2023-53676/index.md)","id":"CVE-2023-53676","markdown":"https://insights.sbomify.com/CVE-2023-53676/index.md","name":"CVE-2023-53676","record":{"aliases":["BELL-CVE-2023-53676","DEBIAN-CVE-2023-53676","GHSA-4832-crwv-4gfx","SUSE-SU-2025:4507-1","UBUNTU-CVE-2023-53676"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel iSCSI","requires_auth":"none","summary":"A buffer overflow in the Linux kernel iSCSI target allows attackers to corrupt memory, potentially leading to code execution or denial of service.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: target: iscsi: Fix buffer overflow in lio_target_nacl_info_show()\n\nThe function lio_target_nacl_info_show() uses sprintf() in a loop to print\ndetails for every iSCSI connection in a session without checking for the\nbuffer length.
