"scenarios": [{"lang": "en", "value": "AV:A - The vulnerable path is Bluetooth HCI event handling (hci_le_cis_estabilished_evt \u2192 hci_conn_add_sysfs) reached when establishing LE Audio/CIS or related links with a nearby Bluetooth peer/controller, so exploitation requires adjacency rather than local shell or routable network access.\nAC:L - An attacker who can drive the HCI event sequence (malicious/buggy controller, or duplicate CIS Established / handle-colliding events) triggers the double device_add reliably; no race or attacker-uncontrollable timing is required.\nPR:N - A nearby Bluetooth peer needs no account or capability on the victim host; connection acceptance is performed by the victim\u2019s normal Bluetooth/LE Audio stack, not by attacker-held OS privileges.\nUI:N - Once Bluetooth is enabled and reachable for CIS/LE connections (common on phones and audio devices), the kernel processes the HCI events asynchronously without further victim action.\nS:U - Impact stays within the host kernel Bluetooth/driver-model authority; this is not a VM escape, IOMMU bypass, or other cross-scope boundary violation.\nC:H - Double device_add corrupts the kobject kset linked list; without list-debug BUG paths this is kernel memory corruption that can be leveraged for arbitrary read primitives, so confidentiality is High.\nI:H - The same list corruption yields classic unlink/write primitives against kernel list pointers, enabling integrity compromise and potential code execution under the required higher-severity rule.\nA:H - With list debugging the double add hits a kernel BUG/oops; without it, corrupted kset lists still cause crashes or hangs when devices are walked or removed, so availability is High."}]}], "affected": [{"product": "Linux", "vendor": "Linux",
