BC-LTS, published on 16 Jul 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-15997 in the wild and no public exploit code.\n\nAffected product: Legion of the Bouncy Castle Inc. BC-LTS. 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-2026-15997/ (Markdown: https://insights.sbomify.com/CVE-2026-15997/index.md)","id":"CVE-2026-15997","markdown":"https://insights.sbomify.com/CVE-2026-15997/index.md","name":"CVE-2026-15997","record":{"aliases":["GHSA-hcmw-xv23-7hqq","UBUNTU-CVE-2026-15997"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Java crypto library","requires_auth":"none","summary":"An integer underflow in ARM SHA3/SHAKE state restoration allows out-of-bounds writes, potentially leading to code execution or denial of service.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"bcorg","cpe":[],"cvss":{"score":1.7,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/S:P/AU:N/R:A/V:D/RE:M/U:Amber","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Out-of-bounds write vulnerability in Legion of the Bouncy Castle Inc.
