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-2026-68157 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-2026-68157/ (Markdown: https://insights.sbomify.com/CVE-2026-68157/index.md)","id":"CVE-2026-68157","markdown":"https://insights.sbomify.com/CVE-2026-68157/index.md","name":"CVE-2026-68157","record":{"aliases":["BELL-CVE-2026-68157","DEBIAN-CVE-2026-68157","GHSA-mr29-956m-24vp","UBUNTU-CVE-2026-68157"],"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 null pointer dereference in the Linux kernel's libceph module allows attackers to cause a denial of service via malformed CRUSH map data.","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":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nlibceph: guard missing CRUSH type name lookup\n\nLocalized read selection can walk a parent bucket whose name exists in\nthe CRUSH map while its type has no matching entry in type_names.\nget_immediate_parent() then dereferences a NULL type_cn and passes an\ninvalid pointer into strcmp(), causing a null-ptr-deref.\n\nSkip such malformed parent buckets unless both the bucket name and type\nname metadata are present.
