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.

Weakness

The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
