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-2025-68248/ (Markdown: https://insights.sbomify.com/CVE-2025-68248/index.md)","id":"CVE-2025-68248","markdown":"https://insights.sbomify.com/CVE-2025-68248/index.md","name":"CVE-2025-68248","record":{"aliases":["BELL-CVE-2025-68248","GHSA-98x7-gjfm-r896","UBUNTU-CVE-2025-68248"],"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 logic error in the Linux kernel's vmw_balloon driver causes a kernel warning and potential instability during page migration, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nvmw_balloon: indicate success when effectively deflating during migration\n\nWhen migrating a balloon page, we first deflate the old page to then\ninflate the new page.\n\nHowever, if inflating the new page succeeded, we effectively deflated the\nold page, reducing the balloon size.\n\nIn that case, the migration actually worked: similar to migrating+\nimmediately deflating the new page.
