CVE-2019-14763

Published: 7 August 2019

In the Linux kernel before 4.16.4, a double-locking error in drivers/usb/dwc3/gadget.c may potentially cause a deadlock with f_hid.

From the Ubuntu Security Team

Tuba Yavuz discovered that a race condition existed in the DesignWare USB3 DRD Controller device driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service.
