In the Linux kernel, the following vulnerability has been resolved:
net: stmmac: fix possible memory leak in stmmac_dvr_probe()
The bitmap_free() should be called to free priv->af_xdp_zc_qps
when create_singlethread_workqueue() fails, otherwise there will
be a memory leak, so we add the err path error_wq_init to fix it.

CVE-2022-50663 [MEDIUM] CWE-771 kernel: net: stmmac: fix possible memory leak in stmmac_dvr_probe()
kernel: net: stmmac: fix possible memory leak in stmmac_dvr_probe()
In the Linux kernel, the following vulnerability has been resolved:
net: stmmac: fix possible memory leak in stmmac_dvr_probe()
The bitmap_free() should be called to free priv->af_xdp_zc_qps
when create_singlethread_workqueue() fails, otherwise there will
be a memory leak, so we add the err path error_wq_init to fix it.
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.
Statement: This is a memory leak in the stmmac Ethernet driver's probe function. The leak occurs only
