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-2022-50034 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-2022-50034/ (Markdown: https://insights.sbomify.com/CVE-2022-50034/index.md)","id":"CVE-2022-50034","markdown":"https://insights.sbomify.com/CVE-2022-50034/index.md","name":"CVE-2022-50034","record":{"aliases":["DEBIAN-CVE-2022-50034","GHSA-7fcf-99gr-mjr2","UBUNTU-CVE-2022-50034"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB driver","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel's cdns3 USB driver allows attackers to cause a denial of service or potentially execute arbitrary code.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","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-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: cdns3 fix use-after-free at workaround 2\n\nBUG: KFENCE: use-after-free read in __list_del_entry_valid+0x10/0xac\n\ncdns3_wa2_remove_old_request()\n{\n\t...\n\tkfree(priv_req-\u003erequest.buf);\n\tcdns3_gadget_ep_free_request(\u0026priv_ep-\u003eendpoint, \u0026priv_req-\u003erequest);\n\tlist_del_init(\u0026priv_req-\u003elist);\n\t^^^ use after free\n\t...\n}\n\ncdns3_gadget_ep_free_request() free the space pointed by priv_req,\nbut priv_req is used in the following list_del_init().\n\nThis patch move list_del_init() before cdns3_gadget_ep_free_request().","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":"usb: cdns3 fix use-after-free at workaround 2","id":"CVE-2022-50034","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"use_after_free","year":"2022"},"n_packages":0,"n_references":5,"next":{"headline":"drm/amdgpu: Fix use-after-free on amdgpu_bo_list mutex","id":"CVE-2022-50035"},"packages":[],"prev":{"headline":"usb: host: ohci-ppc-of: Fix refcount leak bug","id":"CVE-2022-50033"},"products":["Linux"],"published":"2025-06-18","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-15","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel's cdns3 USB driver allows attackers to cause a denial of service or potentially execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2022-50034/"}
