Details

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

wifi: ath11k: Add missing hw_ops->get_ring_selector() for IPQ5018

During sending data after clients connected, hw_ops->get_ring_selector() will be called. But for IPQ5018, this member isn't set, and the following NULL pointer exception will be occurred:
