CVE-2022-50663

Estado: AplazadaSin puntuar—

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.
