It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-3730 exists.\n\nAffected packages and fixed versions:\n- pytorch (Bitnami): affected from 2.6.0; fixed in 2.7.0\n- torch (PyPI): affected all versions; fixed in 2.8.0\n- torch (PyPI): affected all versions; fixed in 2.8.0\n- torch (PyPI): affected all versions; fixed in 2.8.0\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-2025-3730/ (Markdown: https://insights.sbomify.com/CVE-2025-3730/index.md)","id":"CVE-2025-3730","markdown":"https://insights.sbomify.com/CVE-2025-3730/index.md","name":"CVE-2025-3730","record":{"aliases":["AZL-60500","AZL-60577","BIT-pytorch-2025-3730","DEBIAN-CVE-2025-3730","ECHO-60ee-2760-44eb","GHSA-887c-mr87-cxwp","PYSEC-2026-1970","UBUNTU-CVE-2025-3730"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PyTorch machine learning library","requires_auth":"low_privilege","summary":"A local attacker can cause a denial of service in PyTorch via the ctc_loss function, requiring a patch to mitigate.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"pytorch","vendor":"linuxfoundation"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-404","name":"Improper Resource Shutdown or Release"}],"description":"A vulnerability, which was classified as problematic, was found in PyTorch 2.6.0.
