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-2025-61664 in the wild and no public exploit code.\n\nAffected product: GNU Red Hat Enterprise Linux 10. 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-2025-61664/ (Markdown: https://insights.sbomify.com/CVE-2025-61664/index.md)","id":"CVE-2025-61664","markdown":"https://insights.sbomify.com/CVE-2025-61664/index.md","name":"CVE-2025-61664","record":{"aliases":["AZL-70529","AZL-70571","DEBIAN-CVE-2025-61664","GHSA-7w9h-j8xp-j97v","OESA-2025-2795","UBUNTU-CVE-2025-61664"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service","data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GRUB2 bootloader","requires_auth":"none","summary":"An attacker can trigger a use-after-free in GRUB2 by invoking a command after module unload, causing system crashes or compromising data integrity.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":4.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-825","name":"Expired Pointer Dereference"}],"description":"A vulnerability in the GRUB2 bootloader has been identified in the normal module.

An attacker can exploit this condition by invoking the command after the module has been removed, causing the system to improperly access a previously freed memory location.
