How to fix?

Upgrade Centos:8 kernel-rt-core to version 0:4.18.0-147.rt24.93.el8 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-core package and not the kernel-rt-core package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel before 5.0.15 allows a local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not end with a '\0' character.
