CVE-2019-3819

Published: 25 January 2019

A flaw was found in the Linux kernel in the function hid_debug_events_read() in drivers/hid/hid-debug.c file which may enter an infinite loop with certain parameters passed from a userspace. A local privileged user ("root") can cause a system lock up and a denial of service. Versions from v4.18 and newer are vulnerable.

From the Ubuntu Security Team

Vladis Dronov discovered that the debug interface for the Linux kernel's HID subsystem did not properly validate passed parameters in some situations. A local privileged attacker could use this to cause a denial of service (infinite loop).
