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-2019-18683 in the wild and no public exploit code.\n\nAffected product: Broadcom Fabric Operating System. 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-2019-18683/ (Markdown: https://insights.sbomify.com/CVE-2019-18683/index.md)","id":"CVE-2019-18683","markdown":"https://insights.sbomify.com/CVE-2019-18683/index.md","name":"CVE-2019-18683","record":{"aliases":["DEBIAN-CVE-2019-18683","GHSA-fgwh-54wv-865r","UBUNTU-CVE-2019-18683"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel vivid driver","requires_auth":"low_privilege","summary":"Local attackers can exploit race conditions in the vivid driver to trigger a use-after-free, leading to privilege escalation on systems with the driver loaded.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fabric_operating_system","vendor":"broadcom"},{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"},{"product":"8300_firmware","vendor":"netapp"},{"product":"8700_firmware","vendor":"netapp"},{"product":"a400_firmware","vendor":"netapp"},{"product":"a700s_firmware","vendor":"netapp"},{"product":"active_iq_unified_manager","vendor":"netapp"},{"product":"cloud_backup","vendor":"netapp"},{"product":"data_availability_services","vendor":"netapp"},{"product":"e-series_santricity_os_controller","vendor":"netapp"},{"product":"element_software","vendor":"netapp"},{"product":"h610s_firmware","vendor":"netapp"},{"product":"hci_management_node","vendor":"netapp"},{"product":"solidfire","vendor":"netapp"},{"product":"steelstore_cloud_integrated_storage","vendor":"netapp"},{"product":"leap","vendor":"opensuse"}],"cvss":{"score":7,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"},{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded.

These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads.
