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-2021-20322 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-2021-20322/ (Markdown: https://insights.sbomify.com/CVE-2021-20322/index.md)","id":"CVE-2021-20322","markdown":"https://insights.sbomify.com/CVE-2021-20322/index.md","name":"CVE-2021-20322","record":{"aliases":["DEBIAN-CVE-2021-20322","GHSA-x37m-35qq-p254","SUSE-SU-2021:4057-1","SUSE-SU-2021:4075-1","UBUNTU-CVE-2021-20322"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"Remote attackers can bypass UDP source port randomization to scan open ports, compromising confidentiality and potentially integrity.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"linux_kernel","vendor":"linux"},{"product":"active_iq_unified_manager","vendor":"netapp"},{"product":"aff_a700s_firmware","vendor":"netapp"},{"product":"aff_baseboard_management_controller_firmware","vendor":"netapp"},{"product":"e-series_santricity_os_controller","vendor":"netapp"},{"product":"fas_baseboard_management_controller_firmware","vendor":"netapp"},{"product":"h300e_firmware","vendor":"netapp"},{"product":"h300s_firmware","vendor":"netapp"},{"product":"h410s_firmware","vendor":"netapp"},{"product":"h500e_firmware","vendor":"netapp"},{"product":"h500s_firmware","vendor":"netapp"},{"product":"h700e_firmware","vendor":"netapp"},{"product":"h700s_firmware","vendor":"netapp"},{"product":"hci_compute_node_firmware","vendor":"netapp"},{"product":"solidfire\\,_enterprise_sds_\\\u0026_hci_storage_node","vendor":"netapp"},{"product":"solidfire_\\\u0026_hci_management_node","vendor":"netapp"},{"product":"communications_cloud_native_core_binding_support_function","vendor":"oracle"},{"product":"communications_cloud_native_core_network_exposure_function","vendor":"oracle"},{"product":"communications_cloud_native_core_policy","vendor":"oracle"}],"cvss":{"score":7.4,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-330","name":"Use of Insufficiently Random Values"}],"description":"A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux kernel functionality was found to allow the ability to quickly scan open UDP ports.
