Cvss 3 Severity Score

6.8 · Medium

Score breakdown

In parse_hid_report_descriptor in drivers/input/tablet/gtco.c in the Linux kernel through 5.2.1, a malicious USB device can send an HID report that triggers an out-of-bounds write during generation of debugging messages.

From the Ubuntu Security Team

It was discovered that the GTCO tablet input driver in the Linux kernel did not properly bounds check the initial HID report sent by the device. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
