Use the kernel version string together with release documentation and package details to determine whether a capability is supported on your system.

Use the version string to identify the installed RHEL kernel package and to distinguish RHEL kernel builds from non-Red Hat kernels. To determine whether a specific capability is supported on your system, also review the following items:

• RHEL release notes and feature documentation for your major and minor release
• Hardware and software certification and support statements for your platform
• The installed kernel package details, for example, by using the dnf info kernel command

If you rely on vulnerability management or compliance tooling, remember that live kernel patches can fix some issues on the running kernel before a new kernel package is installed. Note that the version string from uname -r alone might not reflect that state.
