Description
A flaw was found in the Linux kernel's ath11k Wi-Fi driver. Specifically, the ath11k_mac_setup_bcn_tmpl_ema() and ath11k_mac_setup_bcn_tmpl_mbssid() functions, responsible for setting up beacon templates, fail to release allocated memory when an error occurs during parameter setup. This oversight can lead to memory leaks, potentially resulting in a Denial of Service (DoS) over time as system resources are exhausted.
