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/GSD-2021-1000466/ (Markdown: https://insights.sbomify.com/GSD-2021-1000466/index.md)","id":"GSD-2021-1000466","markdown":"https://insights.sbomify.com/GSD-2021-1000466/index.md","name":"GSD-2021-1000466","record":{"aliases":[],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"unknown","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A flaw in the Linux kernel powerpc/64s entry flush barrier can cause system crashes, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"powerpc/64s: Fix crashes when toggling entry flush barrier\n\nThis is an automated ID intended to aid in discovery of potential security vulnerabilities.
