There is no fixed version for RHEL:7 kernel-bootwrapper.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-bootwrapper package and not the kernel-bootwrapper package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
pci_iounmap(): Fix MMIO mapping leak
The #ifdef ARCH_HAS_GENERIC_IOPORT_MAP accidentally also guards iounmap(), which means MMIO mappings are leaked.
Move the guard so we call iounmap() for MMIO mappings.
