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-2025-38089 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-2025-38089/ (Markdown: https://insights.sbomify.com/CVE-2025-38089/index.md)","id":"CVE-2025-38089","markdown":"https://insights.sbomify.com/CVE-2025-38089/index.md","name":"CVE-2025-38089","record":{"aliases":["AZL-64398","BELL-CVE-2025-38089","DEBIAN-CVE-2025-38089","GHSA-r4mq-hvhp-3h35","RHSA-2025:12976","RHSA-2025:12977","ROOT-OS-UBUNTU-2404-CVE-2025-38089","UBUNTU-CVE-2025-38089"],"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 remote attacker can crash the Linux kernel by sending a crafted RPC packet that triggers a null pointer dereference in the sunrpc module.","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":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/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\nsunrpc: handle SVC_GARBAGE during svc auth processing as auth error\n\ntianshuo han reported a remotely-triggerable crash if the client sends a\nkernel RPC server a specially crafted packet.

In other cases,\nit could create a memory scribble.\n\nThe server sunrpc code treats a SVC_GARBAGE return from svc_authenticate\nor pg_authenticate as if it should send a GARBAGE_ARGS reply. RFC 5531\nsays that if authentication fails that the RPC should be rejected\ninstead with a status of AUTH_ERR.\n\nHandle a SVC_GARBAGE return as an AUTH_ERROR, with a reason of\nAUTH_BADCRED instead of returning GARBAGE_ARGS in that case.
