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-2025-37740 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2025-37740/ (Markdown: https://insights.sbomify.com/CVE-2025-37740/index.md)","id":"CVE-2025-37740","markdown":"https://insights.sbomify.com/CVE-2025-37740/index.md","name":"CVE-2025-37740","record":{"aliases":["BELL-CVE-2025-37740","DEBIAN-CVE-2025-37740","GHSA-c7x8-xx5v-964j","ROOT-OS-DEBIAN-12-CVE-2025-37740","ROOT-OS-UBUNTU-2204-CVE-2025-37740","ROOT-OS-UBUNTU-2404-CVE-2025-37740","UBUNTU-CVE-2025-37740"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel JFS","requires_auth":"low_privilege","summary":"A missing sanity check in the Linux kernel JFS filesystem allows a local attacker to cause a divide-by-zero error, resulting in a system crash.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-369","name":"Divide By Zero"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\njfs: add sanity check for agwidth in dbMount\n\nThe width in dmapctl of the AG is zero, it trigger a divide error when\ncalculating the control page level in dbAllocAG.\n\nTo avoid this issue, add a check for agwidth in dbAllocAG.","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":"jfs: add sanity check for agwidth in dbMount","id":"CVE-2025-37740","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","linux:linux_kernel"],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":9,"next":{"headline":"jfs: Prevent copying of nlink with value 0 from disk inode","id":"CVE-2025-37741"},"packages":[],"prev":{"headline":"f2fs: fix to avoid out-of-bounds access in f2fs_truncate_inode_blocks()","id":"CVE-2025-37739"},"products":["Linux"],"published":"2025-05-01","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A missing sanity check in the Linux kernel JFS filesystem allows a local attacker to cause a divide-by-zero error, resulting in a system crash.","url":"https://insights.sbomify.com/CVE-2025-37740/"}
