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