"value": "AV:L - The out-of-bounds write occurs in the local HCI device bring-up path (`hci_dev_open_sync` → `hdev->setup` → `btintel_bootloader_setup_tlv`), reached via local ioctl/rfkill/probe rather than from any over-the-air Bluetooth peer; the remote side of the link never controls the corrupting writes.\nAC:L - The out-of-bounds access is unconditional and deterministic — every firmware download clears and sets bits past the end of the `hci_dev` allocation, and every HCI command TX and vendor event RX repeats an OOB `test_bit` with no race or timing dependency.\nPR:L - An unprivileged local user with access to the Bluetooth stack drives the HCI traffic that repeatedly exercises the out-of-bounds flag reads, and any local trigger of device down/up re-runs the corrupting setup path; consistent with other btusb/btnxpuart driver memory CVEs scored PR:L.\nUI:N - No victim action is needed — the corruption happens automatically when the Intel PCIe Bluetooth controller is brought up, typically at boot by bluetoothd, and continues for the device lifetime.\nS:U - The out-of-bounds read/write stays within kernel heap memory under the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Out-of-bounds reads of `btintel_data` (flags bitmap and the `acpi_reset_method` pointer) pull kernel heap contents beyond the allocation, and the resulting heap corruption is of a class leverageable for arbitrary kernel memory disclosure.\nI:H - `set_bit`/`clear_bit`/`test_and_clear_bit` write past the end of the `hci_dev` allocation and a function pointer slot in that OOB region is later dereferenced and called, giving an attacker-influenceable heap write and control-flow primitive depending on adjacent slab layout.\nA:H - The out-of-bounds accesses trip KASAN/slab redzone checks and, where the 16-byte overrun crosses into a neighbouring slab object, corrupt unrelated kernel structures leading to oops or panic."
