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-2023-53828 in the wild and no public exploit code.\n\nAffected product: 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-2023-53828/ (Markdown: https://insights.sbomify.com/CVE-2023-53828/index.md)","id":"CVE-2023-53828","markdown":"https://insights.sbomify.com/CVE-2023-53828/index.md","name":"CVE-2023-53828","record":{"aliases":["BELL-CVE-2023-53828","DEBIAN-CVE-2023-53828","GHSA-jx2x-x589-6cw3","UBUNTU-CVE-2023-53828"],"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 Bluetooth","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel Bluetooth subsystem allows attackers to cause a denial of service or potentially execute code.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: hci_sync: Avoid use-after-free in dbg for hci_add_adv_monitor()\n\nKSAN reports use-after-free in hci_add_adv_monitor().\n\nWhile adding an adv monitor,\n    hci_add_adv_monitor() calls -\u003e\n    msft_add_monitor_pattern() calls -\u003e\n    msft_add_monitor_sync() calls -\u003e\n    msft_le_monitor_advertisement_cb() calls in an error case -\u003e\n    hci_free_adv_monitor() which frees the *moniter.\n\nThis is referenced by bt_dev_dbg() in hci_add_adv_monitor().\n\nFix the bt_dev_dbg() by using handle instead of monitor-\u003ehandle.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Bluetooth: hci_sync: Avoid use-after-free in dbg for hci_add_adv_monitor()","id":"CVE-2023-53828","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"f2fs: flush inode if atomic file is aborted","id":"CVE-2023-53829"},"packages":[],"prev":{"headline":"Bluetooth: L2CAP: Fix use-after-free in l2cap_disconnect_{req,rsp}","id":"CVE-2023-53827"},"products":["Linux"],"published":"2025-12-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel Bluetooth subsystem allows attackers to cause a denial of service or potentially execute code.","url":"https://insights.sbomify.com/CVE-2023-53828/"}
