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-2024-26878 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-2024-26878/ (Markdown: https://insights.sbomify.com/CVE-2024-26878/index.md)","id":"CVE-2024-26878","markdown":"https://insights.sbomify.com/CVE-2024-26878/index.md","name":"CVE-2024-26878","record":{"aliases":["BELL-CVE-2024-26878","DEBIAN-CVE-2024-26878","GHSA-jg7c-h6xh-f8hr","UBUNTU-CVE-2024-26878"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel quota subsystem can lead to a NULL pointer dereference, causing a system crash.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":4.7,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"},{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nquota: Fix potential NULL pointer dereference\n\nBelow race may cause NULL pointer dereference\n\nP1\t\t\t\t\tP2\ndquot_free_inode\t\t\tquota_off\n\t\t\t\t\t  drop_dquot_ref\n\t\t\t\t\t   remove_dquot_ref\n\t\t\t\t\t   dquots = i_dquot(inode)\n  dquots = i_dquot(inode)\n  srcu_read_lock\n  dquots[cnt]) != NULL (1)\n\t\t\t\t\t     dquots[type] = NULL (2)\n  spin_lock(\u0026dquots[cnt]-\u003edq_dqb_lock) (3)\n   ....\n\nIf dquot_free_inode(or other routines) checks inode's quota pointers (1)\nbefore quota_off sets it to NULL(2) and use it (3) after that, NULL pointer\ndereference will be triggered.\n\nSo let's fix it by using a temporary pointer to avoid this issue.","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":"quota: Fix potential NULL pointer dereference","id":"CVE-2024-26878","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","linux:linux_kernel"],"type":"null_dereference","year":"2024"},"n_packages":0,"n_references":9,"next":{"headline":"clk: meson: Add missing clocks to axg_clk_regmaps","id":"CVE-2024-26879"},"packages":[],"prev":{"headline":"crypto: xilinx - call finalize with bh disabled","id":"CVE-2024-26877"},"products":["Linux"],"published":"2024-04-17","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"A race condition in the Linux kernel quota subsystem can lead to a NULL pointer dereference, causing a system crash.","url":"https://insights.sbomify.com/CVE-2024-26878/"}
