Bluetooth: hci_sock: reject out-of-range OCF values

State: Published
Severity: Not scored
Published: Oct 18, 2026
Updated: Oct 19, 2026
Reserved: Sep 25, 2026

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.
