CVE-2026-53113

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

wifi: ath11k: fix memory leaks in beacon template setup

The functions ath11k_mac_setup_bcn_tmpl_ema() and

ath11k_mac_setup_bcn_tmpl_mbssid() allocate memory for beacon templates

but fail to free it when parameter setup returns an error.

Since beacon templates must be released during normal execution, they

must also be released in the error handling paths to prevent memory

leaks.

Fix this by using unified exit paths with proper cleanup in the respective

error paths.

Compile tested only. Issue found using a prototype static analysis tool

and code review.
