Doc Text:	A vulnerability was discovered in the Linux kernel's hns3 network driver. The hns3_nic_net_open() function is designed to be called only once per device instance. However, due to insufficient checks, multiple calls to this function are possible. This can lead to scenarios where hns3_nic_net_open() is invoked concurrently, potentially causing system crashes.
