In the Linux kernel, the following vulnerability has been resolved:

wifi: rtw88: fix the 'para' buffer size to avoid reading out of bounds

Set the size to 6 instead of 2, since 'para' array is passed to
'rtw_fw_bt_wifi_control(rtwdev, para[0], &para[1])', which reads
5 bytes:

void rtw_fw_bt_wifi_control(struct rtw_dev *rtwdev, u8 op_code, u8 *data)
{
...
SET_BT_WIFI_CONTROL_DATA1(h2c_pkt, *data);
SET_BT_WIFI_CONTROL_DATA2(h2c_pkt, *(data + 1));
...
SET_BT_WIFI_CONTROL_DATA5(h2c_pkt, *(data + 4));

Detected using the static analysis tool - Svace.
