CVE-2022-50663

A memory leak vulnerability was found in the stmmac network driver in the Linux kernel. When create_singlethread_workqueue() fails during probe, the previously allocated bitmap (priv->af_xdp_zc_qps) is not freed. This can lead to memory resource exhaustion if the error condition is repeatedly triggered.

This is a memory leak in the stmmac Ethernet driver's probe function. The leak occurs only when workqueue creation fails, which is an uncommon error condition. The impact is limited as it requires specific failure conditions during driver initialization.
