Vulnerability details

The vulnerability allows a local attacker to cause an out-of-bounds write condition on a targeted virtual host system.

The vulnerability exists due to the out-of-bounds write error in the "parse_hid_report_descriptor" function in the "drivers/input/tablet/gtco.c" file. A local authenticated attacker can insert a malicious USB device that sends a crafted response to the targeted system and cause an out-of-bounds write condition.
