Vulnerability from github – Published: 2026-09-17 18:32 – Updated: 2026-09-18 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

HID: synchronize input before cleaning up a failed probe

hid_device_io_start() allows reports to run concurrently with probe. If the probe subsequently fails, __hid_device_probe() releases driver resources and clears hdev->driver without first excluding those report callbacks.

For example, a report may enter hidraw_report_event() while the failure path frees the associated hidraw object, leading to a use-after-free when the report takes the object's list lock.

Stop input before performing failed-probe cleanup. This reacquires driver_input_lock and waits for any report callback already in progress.

Severity

8.8 (High)

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-\u003elist_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-\u003elist_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."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
