"value": "AV:L - Both halves are local — 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()`'s 1500 ms wait plus `_hid_sensor_power_state()`'s `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 — `hid_hw_request()`/`hid_hw_wait()` into `amd_sfh_get_report()`/`amd_sfh_set_report()` — 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's own security authority with no VM, IOMMU, or sandbox boundary crossed.\nC:H - `hid->driver_data` is dereferenced after `kfree()`, so a resprayed kmalloc-64 slot supplies an attacker-chosen `cli_data`, and the subsequent reads of `cli_data->num_hid_devices`, `->sensor_idx[i]`, `->in_data` and `->hid_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 — `cli_data->report_id[i] = report_id`, `->request_done[i] = false`, `->cur_hid_dev = i`, and `list_add(&new->list, &req_list->list)` — while `schedule_delayed_work(&cli_data->work, 0)` and `wake_up_interruptible(&hid_data->hid_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."
