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-2026-22992 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-22992/ (Markdown: https://insights.sbomify.com/CVE-2026-22992/index.md)","id":"CVE-2026-22992","markdown":"https://insights.sbomify.com/CVE-2026-22992/index.md","name":"CVE-2026-22992","record":{"aliases":["AZL-78473","BELL-CVE-2026-22992","DEBIAN-CVE-2026-22992","GHSA-3fqc-v7hh-4m8x","ROOT-OS-DEBIAN-12-CVE-2026-22992","ROOT-OS-DEBIAN-13-CVE-2026-22992","ROOT-OS-UBUNTU-2204-CVE-2026-22992","ROOT-OS-UBUNTU-2404-CVE-2026-22992","UBUNTU-CVE-2026-22992"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A missing error check in the Ceph monitor authentication handler can lead to a NULL pointer dereference and kernel crash.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"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":[{"id":"CWE-476","name":"NULL Pointer Dereference"},{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nlibceph: return the handler error from mon_handle_auth_done()\n\nCurrently any error from ceph_auth_handle_reply_done() is propagated\nvia finish_auth() but isn't returned from mon_handle_auth_done().
