Title
HID: amd_sfh: free driver_data after destroying hid device
Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: amd_sfh: free driver_data after destroying hid device
HID driver callbacks aren't called anymore once hid_destroy_device() has
been called. Hence, hid driver_data should be freed only after the
hid_destroy_device() function returned as driver_data is used in several
callbacks.
I observed a crash with kernel 6.10.0 on my T14s Gen 3, after enabling
KASAN to debug memory allocation, I got this output:

"value": "AV:L - Both halves are local \u2014 the free comes from amd_sfh driver teardown (probe-failure `cleanup:` path or PCI unbind/module unload) and the use comes from `hid_hw_request()` driven through IIO sysfs on the local machine. No network or adjacent-network input reaches `amd_sfh_get_report()`.\nAC:L - An unprivileged process can keep HID callbacks continuously in flight by looping reads of the world-readable `in_*_raw` IIO attributes, and `amdtp_wait_for_response()`\u0027s 1500 ms wait plus `_hid_sensor_power_state()`\u0027s `msleep_interruptible()` leave a multi-millisecond window that is retried at will; reclaiming a 64-byte kmalloc slot from userspace is a standard, reliable spray.\nPR:L - The entire use side \u2014 `hid_hw_request()`/`hid_hw_wait()` into `amd_sfh_get_report()`/`amd_sfh_set_report()` \u2014 is reachable by any local user through 0444 IIO sysfs attributes, and the free side is hit by the probe-time `amd_sfh_hid_client_init()` cleanup path that runs on its own without any privileged action, so no root or real capability is needed by the attacker.\nUI:N - The attacker drives the HID callbacks and the heap grooming itself; the freeing teardown occurs from driver lifecycle events (probe cleanup, unbind) rather than from any action a victim user must be tricked into performing.\nS:U - The freed `struct amdtp_hid_data` and the objects reached through the stale `cli_data` pointer all belong to the kernel itself, so impact stays inside the kernel\u0027s own security authority with no VM, IOMMU, or sandbox boundary crossed.\nC:H - `hid-\u003edriver_data` is dereferenced after `kfree()`, so a resprayed kmalloc-64 slot supplies an attacker-chosen `cli_data`, and the subsequent reads of `cli_data-\u003enum_hid_devices`, `-\u003esensor_idx[i]`, `-\u003ein_data` and `-\u003ehid_sensor_hubs[i]` (fed back to userspace via `hid_input_report()` into IIO values) amount to arbitrary kernel memory disclosure.\nI:H - The same controlled `cli_data` yields writes at attacker-chosen addresses \u2014 `cli_data-\u003ereport_id[i] = report_id`, `-\u003erequest_done[i] = false`, `-\u003ecur_hid_dev = i`, and `list_add(\u0026new-\u003elist, \u0026req_list-\u003elist)` \u2014 while `schedule_delayed_work(\u0026cli_data-\u003ework, 0)` and `wake_up_interruptible(\u0026hid_data-\u003ehid_wait)` operate on freed/forged structures, giving a control-flow hijack primitive.\nA:H - The reported KASAN slab-use-after-free in `amd_sfh_get_report()` is immediately followed by a fatal `Oops: general protection fault, probably for non-canonical address`, so the bug reliably panics the kernel even without full exploitation."

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.
