Description Andrej Nemec 2017-11-22 10:36:30 UTC 
The parse_hid_report_descriptor function in drivers/input/tablet/gtco.c in the Linux kernel before 4.13.11 allows local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device.
