Description
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sock: reject out-of-range OCF values
The raw HCI socket security filter has 128 OCF bits per supported OGF,
but masks the 10-bit OCF with 127 before looking up the command. An
unprivileged socket can therefore submit a reserved OCF that aliases an
allowlisted command modulo 128.
A conforming controller should reject reserved opcodes. Nevertheless,
the security decision must apply to the opcode that will actually be
sent, especially since controller-specific behavior is outside the host
stack's control.
Reject OCF values that cannot be represented by the security filter
instead of aliasing them onto an unrelated command.
