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-2025-13763 exists.\n\nAffected product: OpenSC. 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-2025-13763/ (Markdown: https://insights.sbomify.com/CVE-2025-13763/index.md)","id":"CVE-2025-13763","markdown":"https://insights.sbomify.com/CVE-2025-13763/index.md","name":"CVE-2025-13763","record":{"aliases":["BELL-CVE-2025-13763","DEBIAN-CVE-2025-13763","GHSA-2v44-fq35-98vv","UBUNTU-CVE-2025-13763"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenSC smart card library","requires_auth":"none","summary":"Attackers with physical access can use crafted smart cards to trigger uninitialized variable usage, causing information disclosure or crashes in OpenSC.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":5.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-457","name":"Use of Uninitialized Variable"}],"description":"Multiple uses of uninitialized variables were found in libopensc that may lead to information disclosure or application crash.
