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

wifi: ath11k: fix error path leaks in some WMI WOW calls

Fix two instances where we used to directly return the result of ath11k_wmi_cmd_send(...). Because we did not check the return value, we also did not free the skb in the error path.
