CVE-2017-8925
Published: 12 May 2017
The omninet_open function in drivers/usb/serial/omninet.c in the Linux kernel before 4.10.4 allows local users to cause a denial of service (tty exhaustion) by leveraging reference count mishandling.
From the Ubuntu Security Team
It was discovered that the USB ZyXEL omni.net LCD PLUS driver in the Linux kernel did not properly perform reference counting. A local attacker could use this to cause a denial of service (tty exhaustion).
