CVE-2016-2782 is a medium-severity vulnerability rated 4.6/10 on the CVSS scale. The treo_attach function in drivers/usb/serial/visor.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by inserting a USB device that lacks a (1) bulk-in or (2) interrupt-in endpoint.. EPSS estimates a 1.65% chance of exploitation in the next 30 days.
