How to fix?

There is no fixed version for Centos: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 Centos. See How to fix? for Centos:8 relevant fixed versions and status.

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

KVM: x86: wean fast IN from emulator_pio_in

Use __emulator_pio_in() directly for fast PIO instead of bouncing through emulator_pio_in() now that __emulator_pio_in() fills "val" when handling in-kernel PIO. vcpu->arch.pio.count is guaranteed to be '0', so this a pure nop.

emulator_pio_in_emulated is now the last caller of emulator_pio_in.

No functional change intended.
