"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: synchronize input before cleaning up a failed probe\n\nhid_device_io_start() allows reports to run concurrently with probe. 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."

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."
