Summary
In Qualcomm Android for MSM, Firefox OS for MSM, and QRD Android with all Android releases from CAF using the Linux kernel before security patch level 2018-04-05, in function wma_wow_wakeup_host_event(), wake_info->vdev_id is received from FW and is used directly as array index to access wma->interfaces whose max index should be (max_bssid-1). If wake_info->vdev_id is greater than or equal to max_bssid, an out-of-bounds read occurs.
