"value": "AV:L - The vulnerability is triggered entirely through a local AF_BLUETOOTH HCI control (mgmt) socket by sending a MGMT_OP_SET_MESH_RECEIVER command via sendmsg(); no over-the-air interaction is needed to reach or corrupt memory.\nAC:L - Both defects fire deterministically — any SET_MESH_RECEIVER with param_len > 6 causes the stack out-of-bounds read, and every successful completion hits the double list_del; the optional sock use-after-free variant is a race whose both sides (issuing the command and closing the mgmt fd) are fully attacker-controlled.\nPR:L - Requires a trusted mgmt socket (CAP_NET_ADMIN), the privilege level held by the ordinary non-root Bluetooth daemon on Linux desktops and by Android's sandboxed bluetooth process, so a compromised Bluetooth stack — itself remotely attackable — reaches this with low effective privilege.\nUI:N - The attacker issues the management command directly and no victim action, configuration change, or interaction is required.\nS:U - The out-of-bounds access, list corruption and freed-socket reuse all occur within the kernel's own security authority with no crossing of a VM, IOMMU or sandbox boundary.\nC:H - Up to 16 bytes of adjacent kernel stack are copied into the persistent hdev->mesh_ad_types filter and can be read back byte-by-byte through the mesh_device_found() advertisement-forwarding oracle, and the use-after-free on the released sock additionally exposes reclaimed slab contents.\nI:H - The second list_del writes through LIST_POISON pointers, and the premature sock_put lets mgmt_cmd_complete() write into a freed, sprayable hci_pinfo/sock object (sk_receive_queue, sk_data_ready), which is a control-flow hijack primitive rather than a bounded modification.\nA:H - The double list_del reliably oopses on poison-pointer dereference (or WARNs under CONFIG_DEBUG_LIST), the stack out-of-bounds read is a hard KASAN BUG, and the error path leaks the cmd, its parameters and a socket reference on every failure."
