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-2022-50568 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-2022-50568/ (Markdown: https://insights.sbomify.com/CVE-2022-50568/index.md)","id":"CVE-2022-50568","markdown":"https://insights.sbomify.com/CVE-2022-50568/index.md","name":"CVE-2022-50568","record":{"aliases":["DEBIAN-CVE-2022-50568","GHSA-4jrv-w6c6-f8r5","UBUNTU-CVE-2022-50568"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel USB gadget","requires_auth":"low_privilege","summary":"A use-after-free in the Linux kernel USB HID gadget driver allows local attackers to cause denial of service or escalate privileges by holding a device open during gadget deletion.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: f_hid: fix f_hidg lifetime vs cdev\n\nThe embedded struct cdev does not have its lifetime correctly tied to\nthe enclosing struct f_hidg, so there is a use-after-free if /dev/hidgN\nis held open while the gadget is deleted.\n\nThis can readily be replicated with libusbgx's example programs (for\nconciseness - operating directly via configfs is equivalent):\n\n\tgadget-hid\n\texec 3\u003c\u003e /dev/hidg0\n\tgadget-vid-pid-remove\n\texec 3\u003c\u0026-\n\nPull the existing device up in to struct f_hidg and make use of the\ncdev_device_{add,del}() helpers.
