This value is used as the read length for the ReceiverID\nlist without being clamped to the size of the destination buffer\nrx_id_list[177]. A malicious HDMI repeater could advertise a message\nsize larger than the buffer, causing an out-of-bounds write during the\nI2C read.\n\nClamp the read length in mod_hdcp_read_rx_id_list() to the size of the\nrx_id_list buffer, matching the approach already used in the DP branch.\n\n(cherry picked from commit
