An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-72373 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-2026-72373/ (Markdown: https://insights.sbomify.com/CVE-2026-72373/index.md)","id":"CVE-2026-72373","markdown":"https://insights.sbomify.com/CVE-2026-72373/index.md","name":"CVE-2026-72373","record":{"aliases":["BELL-CVE-2026-72373","DEBIAN-CVE-2026-72373","GHSA-4h6c-mrxr-5r6x","UBUNTU-CVE-2026-72373"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel AFS","requires_auth":"none","summary":"A missing NULL pointer check in the Linux kernel AFS module can cause a system crash when an unknown volume is specified.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nafs: Fix missing NULL pointer check in afs_break_some_callbacks()\n\nFix afs_break_some_callbacks() to check to see if afs_lookup_volume_rcu()\nreturned NULL (e.g. the specified volume is unknown).","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":"afs: Fix missing NULL pointer check in afs_break_some_callbacks()","id":"CVE-2026-72373","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"afs: Fix callback service message parsers to pass through -EAGAIN","id":"CVE-2026-72374"},"packages":[],"prev":{"headline":"afs: Fix lack of locking around modifications of net-\u003ecells_dyn_ino","id":"CVE-2026-72372"},"products":["Linux"],"published":"2026-08-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-16","vendors":["Linux"]},"summary":"A missing NULL pointer check in the Linux kernel AFS module can cause a system crash when an unknown volume is specified.","url":"https://insights.sbomify.com/CVE-2026-72373/"}
