How to fix?

There is no fixed version for RHEL:8 kernel-ipaclones-internal.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-ipaclones-internal package and not the kernel-ipaclones-internal 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: appletouch - initialize work before device registration

Syzbot has reported warning in __flush_work(). This warning is caused by work->func == NULL, which means missing work initialization.

This may happen, since input_dev->close() calls cancel_work_sync(&dev->work), but dev->work initalization happens after input_register_device() call.

So this patch moves dev->work initialization before registering input device
