Description Adam Mariš 2018-01-29 14:06:23 UTC
A flaw was found in the Linux kernel which allowed an attacker who is able to add or remove serial devices to exploit a race condition in the serial port handling.  This would cause the system to panic or possibly have unspecified other impact because the port->exists value can change after it is validated.
