Upgrade RHEL:8 kernel-tools to version 0:4.18.0-553.22.1.el8_10 or higher.

NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-tools package and not the kernel-tools package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
Input: synaptics-rmi4 - fix use after free in rmi_unregister_function()
The put_device() calls rmi_release_function() which frees "fn" so the dereference on the next line "fn->num_of_irqs" is a use after free. Move the put_device() to the end to fix this.
