NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-devel package and not the kernel-uek-devel package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

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.
