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-2022-49980 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-2022-49980/ (Markdown: https://insights.sbomify.com/CVE-2022-49980/index.md)","id":"CVE-2022-49980","markdown":"https://insights.sbomify.com/CVE-2022-49980/index.md","name":"CVE-2022-49980","record":{"aliases":["AZL-70220","DEBIAN-CVE-2022-49980","GHSA-w97r-pxm9-vm23","ROOT-OS-DEBIAN-11-CVE-2022-49980","ROOT-OS-UBUNTU-2204-CVE-2022-49980","UBUNTU-CVE-2022-49980"],"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 USB gadget","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel USB gadget driver allows a use-after-free, potentially leading to system crashes or code execution.","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: gadget: Fix use-after-free Read in usb_udc_uevent()\n\nThe syzbot fuzzer found a race between uevent callbacks and gadget\ndriver unregistration that can cause a use-after-free bug:\n\n---------------------------------------------------------------\nBUG: KASAN: use-after-free in usb_udc_uevent+0x11f/0x130\ndrivers/usb/gadget/udc/core.c:1732\nRead of size 8 at addr ffff888078ce2050 by task udevd/2968\n\nCPU: 1 PID: 2968 Comm: udevd Not tainted 5.19.0-rc4-next-20220628-syzkaller #0\nHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google\n06/29/2022\nCall Trace:\n \u003cTASK\u003e\n __dump_stack lib/dump_stack.c:88 [inline]\n dump_stack_lvl+0xcd/0x134 lib/dump_stack.c:106\n print_address_description mm/kasan/report.c:317 [inline]\n print_report.cold+0x2ba/0x719 mm/kasan/report.c:433\n kasan_report+0xbe/0x1f0 mm/kasan/report.c:495\n usb_udc_uevent+0x11f/0x130 drivers/usb/gadget/udc/core.c:1732\n dev_uevent+0x290/0x770 drivers/base/core.c:2424\n---------------------------------------------------------------\n\nThe bug occurs because usb_udc_uevent() dereferences udc-\u003edriver but\ndoes so without acquiring the udc_lock mutex, which protects this\nfield.
