CVE-2021-47143
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().
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
Description
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.
