If\nthe probe subsequently fails, __hid_device_probe() releases driver\nresources and clears hdev->driver without first excluding those report\ncallbacks.\n\nFor example, a report may enter hidraw_report_event() while the failure\npath frees the associated hidraw object, leading to a use-after-free when\nthe report takes the object's list lock.\n\nStop input before performing failed-probe cleanup. This reacquires\ndriver_input_lock and waits for any report callback already in progress." } ], "metrics": [ { "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 8.8, "baseSeverity": "HIGH" }, "scenarios": [ { "lang": "en", "value": "AV:A - HID input reports that race __hid_device_probe() cleanup after hid_device_io_start() arrive from an adjacent Bluetooth HID peer via hidp_recv_intr_frame() → hidp_process_report() → hid_input_report(). nintendo_hid_probe() for HID_BLUETOOTH_DEVICE Joy-Con/Pro calls hid_hw_start(HID_CONNECT_HIDRAW) then hid_device_io_start() before joycon_init() can fail.\nAC:L - The attacker device both fails probe after hid_device_io_start() (nintendo joycon_init(), or mcp2221 mcp_set_i2c_speed() returning error with io still started) and sends interrupt reports so hidraw_report_event() runs on another CPU while hid_close_report()/hidraw_disconnect() free the object; both sides of the race are attacker-driven.\nPR:N - hid_device_probe() matches and probes the HID device with no host uid, capability, or user-namespace check. A Bluetooth HID peer needs no Linux account; CAP_NET_ADMIN is only required for bluetoothd HIDPCONNADD, not for the peripheral to deliver hidp interrupt frames.\nUI:N - hidp_session_dev_work() calls hid_add_device(), which runs hid_device_probe() automatically once the HIDP session exists; after hid_device_io_start(), interrupt reports are processed with no victim open, mount, or other action (pairing is an attacker prerequisite, not exploit-time UI).\nS:U - The use-after-free is of host-kernel hidraw and hid_report objects inside HID core cleanup; it does not cross a VM, IOMMU, or sandbox boundary.\nC:H - hid_report_raw_event() can enter hidraw_report_event() and take hidraw->list_lock on an object already freed by hidraw_disconnect()/hid_close_report() in the failed-probe path, a use-after-free that can be reused for an arbitrary kernel read.\nI:H - The same freed hidraw/hid_report object is written (list_lock, kmemdup into list buffers) and can be sprayed, yielding an arbitrary write or control-flow hijack primitive from the in-flight report callback.\nA:H - hidraw_report_event() taking the freed hidraw->list_lock, or hid_get_report() walking reports already freed by hid_close_report(), oopses or panics the kernel even when the UAF is not fully exploited." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
