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-2025-38471 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2025-38471/ (Markdown: https://insights.sbomify.com/CVE-2025-38471/index.md)","id":"CVE-2025-38471","markdown":"https://insights.sbomify.com/CVE-2025-38471/index.md","name":"CVE-2025-38471","record":{"aliases":["AZL-65949","BELL-CVE-2025-38471","DEBIAN-CVE-2025-38471","GHSA-8r96-vh27-xgf4","RHSA-2025:14497","RHSA-2025:14599","RHSA-2025:14811","ROOT-OS-DEBIAN-12-CVE-2025-38471","ROOT-OS-UBUNTU-2404-CVE-2025-38471","UBUNTU-CVE-2025-38471"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel TLS","requires_auth":"none","summary":"A use-after-free bug in the Linux kernel TLS module allows attackers to cause a system crash or potentially execute arbitrary code.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ntls: always refresh the queue when reading sock\n\nAfter recent changes in net-next TCP compacts skbs much more\naggressively.
