Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
wifi: ath12k: change DMA direction while mapping reinjected packets<br />
<br />
For fragmented packets, ath12k reassembles each fragment as a normal<br />
packet and then reinjects it into HW ring. In this case, the DMA<br />
direction should be DMA_TO_DEVICE, not DMA_FROM_DEVICE. Otherwise,<br />
an invalid payload may be reinjected into the HW and<br />
subsequently delivered to the host.<br />
<br />
Given that arbitrary memory can be allocated to the skb buffer,<br />
knowledge about the data contained in the reinjected buffer is lacking.<br />
Consequently, there’s a risk of private information being leaked.<br />
<br />
