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 (βrootβ) can cause a system lock up and a denial of
service. Versions from v4.18 and newer are vulnerable.
