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-2024-47664 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-2024-47664/ (Markdown: https://insights.sbomify.com/CVE-2024-47664/index.md)","id":"CVE-2024-47664","markdown":"https://insights.sbomify.com/CVE-2024-47664/index.md","name":"CVE-2024-47664","record":{"aliases":["AZL-50860","BELL-CVE-2024-47664","DEBIAN-CVE-2024-47664","GHSA-wccr-cp5j-5ggc","ROOT-OS-DEBIAN-12-CVE-2024-47664","ROOT-OS-UBUNTU-2204-CVE-2024-47664","UBUNTU-CVE-2024-47664"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel SPI driver","requires_auth":"low_privilege","summary":"A division by zero error in the Hisi Kunpeng SPI driver can cause a system crash if the firmware provides an invalid max frequency.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-369","name":"Divide By Zero"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nspi: hisi-kunpeng: Add verification for the max_frequency provided by the firmware\n\nIf the value of max_speed_hz is 0, it may cause a division by zero\nerror in hisi_calc_effective_speed().\nThe value of max_speed_hz is provided by firmware.\nFirmware is generally considered as a trusted domain.
