How to fix?

Upgrade Rocky-Linux:8 kernel-rt-debug-devel to version 0:4.18.0-553.22.1.rt7.363.el8_10 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-debug-devel package and not the kernel-rt-debug-devel package as distributed by Rocky-Linux. See How to fix? for Rocky-Linux: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.
