CVE-2018-20169
Published: 17 December 2018
An issue was discovered in the Linux kernel before 4.19.9. The USB subsystem mishandles size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c.
From the Ubuntu security team
Hui Peng and Mathias Payer discovered that the USB subsystem in the Linux kernel did not properly handle size checks when handling an extra USB descriptor. A physically proximate attacker could use this to cause a denial of service (system crash).
