Consequently, if\nthe device is removed while aes_battery_work is still pending, then hard\ncrashes or \"Oops: general protection fault...\" are experienced when\nwacom_aes_battery_handler() is finally called. E.g., this happens with\nbuilt-in USB devices after resume from hibernate when aes_battery_work\nwas still pending at the time of hibernation.\n\nSo, take care to cancel aes_battery_work in wacom_remove()."

"value": "AV:A - The wacom driver binds any Bluetooth HID device presenting Wacom's vendor ID via `BT_DEVICE_WACOM(HID_ANY_ID)` and hid-core's forced `HID_GROUP_WACOM`, so an attacker within Bluetooth range supplying a crafted report descriptor and pen reports reaches the vulnerable path. This matches the adjacent-network scoring used for other Wacom HID report-processing flaws.\nAC:L - The attacker device controls every step — the report descriptor that sets WACOM_QUIRK_AESPEN, the pen report with sense=0 that arms the work, and the disconnect that frees `struct wacom` — and the 30-minute delay window guarantees the work is still pending at removal. No race must be won and no uncontrollable state is required.\nPR:N - Everything happens inside kernel HID transport and driver probe/report/remove handling; no user account, credential, or capability on the target is involved. The attacker only needs their device connected to the host.\nUI:N - Once the device is connected, arming the delayed work and then tearing down the link are entirely device-driven with no action by any user on the target. Consistent with prior Wacom HID CVEs scored UI:N.\nS:U - The use-after-free corrupts kernel heap memory and executes within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed devm-allocated `struct wacom` is a sprayable slab object whose contents are subsequently used as a workqueue pointer, work function pointer, and `hdev` pointer, giving an attacker who grooms the slab an arbitrary-read/kernel-memory-disclosure primitive.\nI:H - `process_one_work()` invokes `work->func()` read from the freed object and `devres_release_group()` walks stale list data invoking release callbacks, yielding control-flow hijack and arbitrary-write potential; the leftover armed timer in the timer wheel adds list-corruption write primitives.\nA:H - The commit explicitly reports \"hard crashes or 'Oops: general protection fault'\" when the pending work fires after device removal, and the attacker can trigger this repeatedly by reconnecting and disconnecting."
