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-2025-38477 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-2025-38477/ (Markdown: https://insights.sbomify.com/CVE-2025-38477/index.md)","id":"CVE-2025-38477","markdown":"https://insights.sbomify.com/CVE-2025-38477/index.md","name":"CVE-2025-38477","record":{"aliases":["AZL-65907","AZL-73046","BELL-CVE-2025-38477","DEBIAN-CVE-2025-38477","GHSA-79vc-v8qm-8x53","OESA-2025-2057","ROOT-OS-DEBIAN-11-CVE-2025-38477","ROOT-OS-DEBIAN-12-CVE-2025-38477","ROOT-OS-UBUNTU-2204-CVE-2025-38477","ROOT-OS-UBUNTU-2404-CVE-2025-38477","SUSE-SU-2025:03473-1","SUSE-SU-2025:03479-1","SUSE-SU-2025:03485-1","SUSE-SU-2025:03497-1","SUSE-SU-2025:03550-1","SUSE-SU-2025:03552-1","SUSE-SU-2025:03562-1","SUSE-SU-2025:03568-1","SUSE-SU-2025:03576-1","SUSE-SU-2025:03583-1","SUSE-SU-2025:20812-1","SUSE-SU-2025:20820-1","SUSE-SU-2025:20839-1","SUSE-SU-2025:20842-1","UBUNTU-CVE-2025-38477"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"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's QFQ scheduler allows attackers to trigger use-after-free or NULL dereference, potentially causing crashes or code execution.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sched: sch_qfq: Fix race condition on qfq_aggregate\n\nA race condition can occur when 'agg' is modified in qfq_change_agg\n(called during qfq_enqueue) while other threads access it\nconcurrently.
