Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
wifi: ath11k: fix memory leak in WMI firmware stats<br />
<br />
Memory allocated for firmware pdev, vdev and beacon statistics<br />
are not released during rmmod.<br />
<br />
Fix it by calling ath11k_fw_stats_free() function before hardware<br />
unregister.<br />
<br />
While at it, avoid calling ath11k_fw_stats_free() while processing<br />
the firmware stats received in the WMI event because the local list<br />
is getting spliced and reinitialised and hence there are no elements<br />
in the list after splicing.<br />
<br />
