[ol8_baseos_latest] kernel-4.18.0-425.19.2.el8_7.x86_64

This is the package which provides the Linux kernel for Red Hat Enterprise
Linux. It is based on upstream Linux at version 4.18.0 and maintains kABI
compatibility of a set of approved symbols, however it is heavily modified with
backports and fixes pulled from newer upstream Linux kernel releases. This means
this is not a 4.18.0 kernel anymore: it includes several components which come
from newer upstream linux versions, while maintaining a well tested and stable
core. Some of the components/backports that may be pulled in are: changes like
updates to the core kernel (eg.: scheduler, cgroups, memory management, security
fixes and features), updates to block layer, supported filesystems, major driver
updates for supported hardware in Red Hat Enterprise Linux, enhancements for
enterprise customers, etc.
