How to fix?

There is no fixed version for Centos:8 kernel-debug-modules-internal.

NVD Description

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

In the Linux kernel, the following vulnerability has been resolved:

USB: serial: fix ioctl hangup race

The tty ioctls can race with hangup and end up calling into a tty driver for a device that is already gone or powered down.

Serialise the callbacks using the tty port mutex and add the missing checks to make sure the port has not been hung up before accessing port driver data or hardware.

This specifically avoids dereferencing a NULL-pointer if a device is disconnected during lengthy break signalling.

Note that TIOCGICOUNT and TIOCMIWAIT do not access port driver data or hardware and are therefore not affected by the race.
