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-2025-0684 in the wild and no public exploit code.\n\nAffected product: 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-2025-0684/ (Markdown: https://insights.sbomify.com/CVE-2025-0684/index.md)","id":"CVE-2025-0684","markdown":"https://insights.sbomify.com/CVE-2025-0684/index.md","name":"CVE-2025-0684","record":{"aliases":["AZL-57678","AZL-57707","BELL-CVE-2025-0684","DEBIAN-CVE-2025-0684","GHSA-mf4f-2vjv-3rq6","UBUNTU-CVE-2025-0684"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GRUB2 bootloader","requires_auth":"high_privilege","summary":"A malicious ReiserFS filesystem can trigger an integer overflow in GRUB2, leading to heap corruption and arbitrary code execution that bypasses Secure Boot.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"grub2","vendor":"gnu"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A flaw was found in grub2. When performing a symlink lookup from a reiserfs filesystem, grub's reiserfs fs module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size, however, it improperly checks for integer overflows. A maliciouly crafted filesystem may lead some of those buffer size calculations to overflow, causing it to perform a grub_malloc() operation with a smaller size than expected. As a result, the grub_reiserfs_read_symlink() will call grub_reiserfs_read_real() with a overflown length parameter, leading to a heap based out-of-bounds write during data reading. This flaw may be leveraged to corrupt grub's internal critical data and can result in arbitrary code execution, by-passing secure boot protections.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Grub2: reiserfs: integer overflow when handling symlinks may lead to heap based out-of-bounds write when reading data","id":"CVE-2025-0684","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"Grub2: jfs: integer overflow when handling symlinks may lead to heap based out-of-bounds write when reading data","id":"CVE-2025-0685"},"packages":[],"prev":{"headline":"Information disclosure in CMS8000 Patient Monitor","id":"CVE-2025-0683"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9","Red Hat OpenShift Container Platform 4"],"published":"2025-03-03","related":[{"cvss_score":8.8,"headline":"Memory corruption in GRUB2","id":"CVE-2024-56737","kev_date_added":null,"published":"2024-12-29"},{"cvss_score":8.1,"headline":"Integer underflow in grub_net_recv_ip4_packets","id":"CVE-2022-28733","kev_date_added":null,"published":"2023-07-20"},{"cvss_score":8.1,"headline":"Out-of-bounds write when handling split HTTP headers","id":"CVE-2022-28734","kev_date_added":null,"published":"2023-07-20"},{"cvss_score":7.8,"headline":"Grub2: missing unregister call for gettext command may lead to use-after-free","id":"CVE-2025-61662","kev_date_added":null,"published":"2025-11-18"},{"cvss_score":7.8,"headline":"Grub2: fs/hfs: strcpy() using the volume name (fs/hfs.c:382)","id":"CVE-2024-45782","kev_date_added":null,"published":"2025-03-03"},{"cvss_score":7.8,"headline":"Grub2: squash4: integer overflow may lead to heap based out-of-bounds write when reading data","id":"CVE-2025-0678","kev_date_added":null,"published":"2025-03-03"},{"cvss_score":7.8,"headline":"Grub2: udf: heap based buffer overflow in grub_udf_read_block() may lead to arbitrary code execution","id":"CVE-2025-0689","kev_date_added":null,"published":"2025-03-03"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-21","vendors":["Red Hat"]},"summary":"A malicious ReiserFS filesystem can trigger an integer overflow in GRUB2, leading to heap corruption and arbitrary code execution that bypasses Secure Boot.","url":"https://insights.sbomify.com/CVE-2025-0684/"}
