CVSS V2.0分值：
BaseScore：0.0 Low
Vector：CVSS：2.0/
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:net/smc: remove device from smcd_dev_list after failed device_add()If the device_add() for a smcd_dev fails, there s no cleanup step thatrolls back the earlier list_add(). The device subsequently gets freed,and we end up with a corrupted list.Add some error handling that removes the device from the list.

CVE-2021-47143

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

net/smc: remove device from smcd_dev_list after failed device_add()

If the device_add() for a smcd_dev fails, there's no cleanup step that
rolls back the earlier list_add(). The device subsequently gets freed,
and we end up with a corrupted list.

Add some error handling that removes the device from the list.
