It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-68724 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2025-68724/ (Markdown: https://insights.sbomify.com/CVE-2025-68724/index.md)","id":"CVE-2025-68724","markdown":"https://insights.sbomify.com/CVE-2025-68724/index.md","name":"CVE-2025-68724","record":{"aliases":["AZL-73159","BELL-CVE-2025-68724","DEBIAN-CVE-2025-68724","GHSA-fhmc-454p-hp6f","ROOT-OS-DEBIAN-11-CVE-2025-68724","ROOT-OS-DEBIAN-12-CVE-2025-68724","ROOT-OS-UBUNTU-2204-CVE-2025-68724","ROOT-OS-UBUNTU-2404-CVE-2025-68724","UBUNTU-CVE-2025-68724"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"An integer overflow in the Linux kernel's asymmetric key generation allows attackers to trigger buffer overflows via malicious X.509 certificates, potentially leading to code execution or crashes.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: asymmetric_keys - prevent overflow in asymmetric_key_generate_id\n\nUse check_add_overflow() to guard against potential integer overflows\nwhen adding the binary blob lengths and the size of an asymmetric_key_id\nstructure and return ERR_PTR(-EOVERFLOW) accordingly.
