Description

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 …
