In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: 8822b: Avoid WARNING in rtw8822b_config_trx_mode()
rtw8822b_set_antenna() can be called from userspace when the chip is powered off. In that case a WARNING is triggered in rtw8822b_config_trx_mode() because trying to read the RF registers when the chip is powered off returns an unexpected value.
Call rtw8822b_config_trx_mode() in rtw8822b_set_antenna() only when the chip is powered on.
