"value": "AV:L - The exploitable window is opened by a local action that stops the device (`ip link set down`, suspend, rfkill, driver unbind) — a remote or adjacent Wi-Fi attacker can queue `c2hcmd_work` but cannot cause `rtl8xxxu_stop()`/`ieee80211_free_hw()` to run. This matches the AV:L scoring of the directly analogous `rtl8187_stop()` teardown UAF (CVE-2025-38604).\nAC:L - The attacker controls both sides of the race: Wi-Fi/BT-coex activity keeps C2H events and RA reports flowing so `schedule_work(&priv->c2hcmd_work)` fires continuously, and the attacker chooses the exact moment to trigger the stop/unbind, so the window can be hit repeatedly until won.\nPR:L - An ordinary local user in a normal desktop/embedded session can reach the teardown path via logind-mediated suspend or rfkill, and no capability is needed to generate the Wi-Fi traffic that keeps the work queued; consistent with PR:L used across the driver-teardown UAF class.\nUI:N - The attacker performs both the traffic generation and the interface stop themselves; no separate victim has to open a file, mount anything, or take any action.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The freed `rtl8xxxu_priv` slab object can be reclaimed and groomed by the attacker, and the work callback reads through it (`priv->fops`, `priv->udev->dev`, `priv->c2hcmd_queue`), yielding a use-after-free read primitive that can disclose arbitrary kernel memory.\nI:H - The stale work item writes into the freed object (skb dequeue/list manipulation on `c2hcmd_queue`, updates to `priv->ra_report` and `priv->bt_coex`), and the workqueue core manipulates the freed embedded `work_struct`, giving a controlled-write primitive on reclaimed heap memory that is leverageable for control-flow hijack.\nA:H - Even unexploited, the use-after-free reliably produces a kernel oops or panic when the work runs against freed memory, and it can be retriggered on every device stop."
