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-2022-50339 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-2022-50339/ (Markdown: https://insights.sbomify.com/CVE-2022-50339/index.md)","id":"CVE-2022-50339","markdown":"https://insights.sbomify.com/CVE-2022-50339/index.md","name":"CVE-2022-50339","record":{"aliases":["DEBIAN-CVE-2022-50339","GHSA-6wf7-5hh8-x7vm","UBUNTU-CVE-2022-50339"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel Bluetooth","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel Bluetooth subsystem can lead to a denial of service by attempting to cancel uninitialized work.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"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\nBluetooth: avoid hci_dev_test_and_set_flag() in mgmt_init_hdev()\n\nsyzbot is again reporting attempt to cancel uninitialized work\nat mgmt_index_removed() [1], for setting of HCI_MGMT flag from\nmgmt_init_hdev() from hci_mgmt_cmd() from hci_sock_sendmsg() can\nrace with testing of HCI_MGMT flag from mgmt_index_removed() from\nhci_sock_bind() due to lack of serialization via hci_dev_lock().\n\nSince mgmt_init_hdev() is called with mgmt_chan_list_lock held, we can\nsafely split hci_dev_test_and_set_flag() into hci_dev_test_flag() and\nhci_dev_set_flag().
