CVE-2018-20169

Priority
Description
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.
Ubuntu-Description
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).
Notes
tyhicksThis issue requires physical access and, therefore, is being rated as
a low priority issue
