In the Linux kernel, the following vulnerability has been resolved: wifi: mwifiex: fix permanently busy scans after multiple roam iterations In order for the firmware to sleep, the driver has to confirm a previously received sleep request. The normal sequence of evets goes like this: EVENT_SLEEP -> adapter->ps_state = PS_STATE_PRE_SLEEP -> sleep-confirm -> SLEEP -> EVENT_AWAKE -> AWAKE. Before sending the sleep-confirm command, the driver must make sure there are no commands either running or waiting to be completed. mwifiex_ret_802_11_associate() unconditionally sets ps_state = PS_STATE_AWAKE when it processes the association command response, outside of the normal powersave management flow.
