Title
net: wangxun: fix kernel panic due to null pointer
Summary
In the Linux kernel, the following vulnerability has been resolved: net: wangxun: fix kernel panic due to null pointer When the device uses a custom subsystem vendor ID, the function wx_sw_init() returns before the memory of 'wx->mac_table' is allocated. The null pointer will causes the kernel panic.
Severity
